[0032] As Figures 1-8 shown, a kind of extendable nasal aspirator according to the first aspect embodiment of the present utility model includes a housing 100, a catheter assembly 200, and a nasal aspirating assembly 300. A pump body assembly 410 is provided in the housing 100. The catheter assembly 200 passes through the housing 100 and the head end of the catheter assembly 200 is docked with the pump body assembly 410. The nasal aspirating assembly 300 has a storage cavity 310 and an air extraction port 320. The nasal aspirating assembly 300 has an insertion nose part 330, and a nasal mucus suction port 340 is arranged in the insertion nose part 330. The storage cavity 310 is respectively communicated with the air extraction port 320 and the nasal mucus suction port 340. The tail end of the catheter assembly 200 is docked with the air extraction port 320.

[0033] Among them, the housing 100 can be in a disc shape or a column shape, such as a disc shape, a cuboid shape or other irregular shapes. The housing 100 is used to be placed on a plane, and the nasal suction assembly 300 can be in a long handle shape for easy user grip. The pump assembly 410 can be a conventional liquid pumping pump or a gas pumping pump. The extraction end of the pump assembly 410 is directly or indirectly connected to the head end of the conduit assembly 200, so as to apply pressure to the nasal discharge port 340 through the conduit assembly 200 to suck nasal mucus.

[0034] Specifically, a control panel 420 can also be provided on the surface of the housing 100. The control panel 420 is provided with push buttons or a touch screen, etc. A circuit board 430 is provided inside the housing 100. A controller is provided on the circuit board 430. The controller is respectively connected to the control panel 420 and the pump assembly 410. The user can input control instructions on the control panel 420, and the controller then controls the start / stop or speed regulation of the pump assembly 410 according to the control instructions.

[0035] The nasal insertion part 330 can be in a conical shape to facilitate insertion into the nostril.

[0036] For the extendable nasal suction device of the present utility model, the pump assembly 410 is arranged inside the housing 100. The pump assembly 410 is connected to the nasal suction assembly 300 through the conduit assembly 200. The nasal suction assembly 300 has a nasal insertion part 330. The user can hold the nasal suction assembly 300 close to the nostril and insert the nasal insertion part 330 into the nostril. A storage cavity 310 is arranged inside the nasal suction assembly 300. When the pump assembly 410 operates to provide suction, nasal mucus will enter the storage cavity 310 from the nasal discharge port 340 for storage. Since the nasal suction assembly 300 only needs to be provided with the storage cavity 310, the volume can be smaller, which is convenient for the user to hold and operate. And the length of the conduit assembly 200 can be selected, and the nasal suction assembly 300 can be extended to any area. This design is flexible and convenient to use, meeting the user's usage requirements.

[0037] In some embodiments of the present utility model, the conduit assembly 200 is made of a flexible material. Specifically, the conduit assembly 200 can be selected from rubber, resin or flexible alloy. The conduit assembly 200 can be bent at will, which is convenient for the user to move to various positions and can be inserted into the nostril more accurately.

[0038] In some embodiments of the present utility model, as Figure 3 shown, a winding structure 500 is provided on the housing 100, and the conduit assembly 200 can be wound around the winding structure 500.

[0039] The catheter assembly 200 has a certain length. When the nasal aspirator is no longer in use or when the user is relatively close to the housing 100 during use, the catheter assembly 200 can be at least partially wound around the winding structure 500, which facilitates storage, saves space, and is not likely to damage the catheter assembly 200.

[0040] In some embodiments of the present utility model, as Figure 3 , 7 shown, the winding structure 500 includes a baffle 510 and a support column 520. One end of the support column 520 is connected to the housing 100, and the other end of the support column 520 is connected to the baffle 510. The wall surface of the baffle 510, the outer peripheral wall of the support column 520, and the outer wall surface of the housing 100 define a limiting groove 530. The catheter assembly 200 can be wound around the support column 520 and the catheter assembly 200 is located in the limiting groove 530.

[0041] The support column 520 protrudes from the surface of the housing 100 and forms a support for the baffle 510. The edge of the baffle 510 protrudes from the peripheral wall of the support column 520. The catheter assembly 200 is wound around the support column 520, and the wall surface of the baffle 510 can prevent the catheter assembly 200 from slipping out of the end of the support column 520.

[0042] In some embodiments of the present utility model, as Figure 7 , 8 shown, a buffer chamber 110 is further provided in the housing 100. The housing 100 is provided with a nasal mucus inlet 120 and a nasal mucus outlet 130 that communicate with the buffer chamber 110. The first end of the catheter assembly 200 is docked with the nasal mucus inlet 120, and the pump body assembly 410 is docked with the nasal mucus outlet 130.

[0043] Generally speaking, when nasal mucus enters the pump body assembly 410, it is rather troublesome to clean the pump body assembly 410. Therefore, the catheter assembly 200 is usually made of a transparent material. When the user is performing nasal aspiration, if it is observed that nasal mucus enters the catheter assembly 200, it indicates that the storage chamber 310 is full, and the user can stop the nasal aspiration operation and clean the nasal aspirator to prevent nasal mucus from entering the pump body assembly 410.

[0044] However, sometimes the user fails to observe in time that nasal mucus enters the catheter assembly 200. Therefore, the buffer chamber 110 can pre-store the nasal mucus. After the nasal mucus enters the buffer chamber 110 from the first end of the catheter assembly 200, the nasal mucus will not immediately enter the pump body assembly 410, providing the user with sufficient reaction time.

[0045] Specifically, the buffer cavity 110 can be formed between the support column 520 and the housing 100. The support column 520 is hollow inside, and the housing 100 is concave. The support column 520 is connected to the housing 100 to enclose the buffer cavity 110. An inlet for nasal mucus 120 is formed by opening on the peripheral wall of the support column 520, and an outlet for nasal mucus 130 is formed by opening at the position of the housing 100 corresponding to the buffer cavity 110.

[0046] In some embodiments of the present utility model, as Figure 7 、 8 shown, the housing 100 is provided with a cleaning port communicating with the buffer cavity 110. One end of the support column 520 is detachably connected to the housing 100 to be able to close or open the cleaning port.

[0047] When it is necessary to clean the nasal mucus, the housing 100 and the support column 520 can be separated from each other, so as to open the cleaning port for easy cleaning. The housing 100 and the support column 520 can be connected by a threaded structure or a snap structure. The housing 100 can protrude to form a connecting ring at the edge of the cleaning port, and the support column 520 can be sleeved on the connecting ring to make the connection tight. A sealing ring made of an elastic material can be arranged between the outer peripheral wall of the connecting ring and the inner peripheral wall of the support column 520, so as to ensure good airtightness and prevent nasal mucus leakage.

[0048] After the nasal mucus enters the storage cavity 310, in order to prevent a small amount of nasal mucus from being discharged from the air extraction port 320 under the pressure of the pump body assembly 410, in some embodiments of the present utility model, as Figure 4 、 5 shown, the nasal suction assembly 300 is provided with an extension member 600 in the storage cavity 310. A nasal mucus guiding channel 610 is arranged inside the extension member 600. An input port 620 and an output port 630 communicating with the nasal mucus guiding channel 610 are arranged at both ends of the extension member 600. The output port 630 is docked with the air extraction port 320, and the input port 620 protrudes from the inner wall surface of the storage cavity 310.

[0049] The extension member 600 protrudes from the inner wall surface of the storage cavity 310, so that the input port 620 is higher than the inner wall surface of the storage cavity 310. The stored nasal mucus needs to be higher than the height at which the extension member 600 protrudes from the inner wall surface of the storage cavity 310 in the storage cavity 310 before the nasal mucus can enter the nasal mucus guiding channel 610 from the input port 620, and is discharged into the catheter assembly 200 through the nasal mucus guiding channel 610, the output port 630, and the air extraction port 320. It can be from Figure 4 、 5As can be seen, the air extraction port 320 and the snot suction port 340 are respectively located at two ends of the nose suction assembly 300. In the use state, the snot suction port 340 is above the gravity direction, while the air extraction port 320 is below the gravity direction. And due to the presence of the extension member 600, the input port 620 is set at a position near the middle of the storage cavity 310, and snot that has not reached a certain stockpile is not likely to flow out from the input port 620.

[0050] In some embodiments of the present utility model, such as Figure 4 , 5 shown, the extension member 600 is tubular, the input port 620 is arranged on the peripheral wall of the extension member 600, and the extension member 600 is sleeved with retaining ring members 640 at both the front and rear ends of the input port 620 along the length direction of the extension member 600.

[0051] The retaining ring member 640 is annular and sleeved on the extension member 600, and there are at least two retaining ring members 640, which are arranged at both the front and rear ends of the extension member 600 at the input port 620 along the length direction of the extension member 600. Thus, due to the blocking of the retaining ring member 640, snot with a small stockpile is not likely to enter the input port 620. In addition, in the use state, the snot suction port 340 is above the gravity direction, while the air extraction port 320 is below the gravity direction, and snot entering from the snot suction port 340 is not likely to drip onto the input port 620 and then enter the input port 620.

[0052] In some embodiments of the present utility model, such as Figure 5 shown, the nose suction assembly 300 includes a bottom cover 350 and a top cover 360, and the bottom cover 350 and the top cover 360 are detachably connected to define the storage cavity 310.

[0053] The snot suction port 340 can be arranged on the top cover 360, while the air extraction port 320, the extension member 600, etc. can be arranged on the bottom cover 350. The top cover 360 and the bottom cover 350 can be sleeved with each other and connected through a threaded structure and a snap structure. Separating the bottom cover 350 and the top cover 360 can open the storage cavity 310, so as to discharge the snot in the storage cavity 310 and clean the nose suction assembly 300.

[0054] In some embodiments of the present utility model, such as Figure 1 , 2 shown, the extendable nose suction device further includes a finger sleeve set 700. The finger sleeve set 700 includes an assembly port 710 and a finger sleeve port 720. The nose suction assembly 300 can be inserted into the assembly port 710 so that the nose suction assembly 300 is detachably connected to the finger sleeve set 700, and the finger sleeve port 720 is used for sleeving on a finger.

[0055] The user's finger can pass through the finger sleeve opening 720, and then hold the nasal aspirator assembly 300, which makes the holding more firm and the use more convenient.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0057] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
