[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0047] The present utility model embodiment provides a nasal washer 1000, such as Figures 1 to 3 As shown, the nasal wash device 1000 includes a housing 10, an air pump 20, a nasal wash structure 40, a nozzle holder 30 and an external battery assembly 50. The housing 10 is provided with an installation cavity 11 and a liquid storage cavity 12. The liquid storage cavity 12 is arranged on one side of the installation cavity 11. The liquid storage cavity 12 is used to store nasal wash liquid. The nasal wash liquid can be physiological saline or medicinal saline. A first magnetic attraction member 13 is installed on the housing 10. The air pump 20 is installed in the installation cavity 11. The nasal wash structure 40 is arranged in the liquid storage cavity 12. The nasal washing structure 40 is connected to the air pump 20, and is used to use the air source provided by the air pump 20 to disperse the nasal washing liquid; the nozzle holder 30 is installed on the housing 10, and the nozzle holder 30 is connected to the nasal washing structure 40; the external battery assembly 50 is provided with a second magnetic component 51, and the second magnetic component 51 is attracted to the first magnetic component 13, so that the external battery assembly 50 can be detachably installed on the outside of the housing 10, and the external battery assembly 50 is electrically connected to the air pump 20 to supply power to the air pump 20.

[0048] The nasal washer 1000 of the present application can not only provide nasal washing for the user, but also is convenient for the user to carry, and its portability is better.

[0049] Specifically, the air pump 20 acts on the nose washing structure 40 to generate compressed air, guiding the nose washing liquid in the liquid storage chamber to flow into the nose washing structure 40 and be dispersed and sprayed out of the housing 10 by the nozzle holder 30, thereby providing the user with a nose washing function. In addition, the nose washing device 1000 uses an external battery assembly 50 installed outside the housing 10 to power the air pump 20. Compared with the embodiment of the nose washing device using a built-in battery in the prior art, the external battery assembly 50 can reduce the occupation of the internal space of the housing 10, and the external battery assembly 50 will not have a negative impact on the layout of the internal components of the housing 10, so as to improve the utilization rate of the internal space of the housing 10, and then when the housing 10 is manufactured, the size of the housing 10 is small and convenient to carry.

[0050] In addition, in the present application, the external battery assembly 50 is detachably connected to the housing 10. The user can place the external battery assembly 50 and the housing 10 as a whole according to the actual storage space size, or separate the two and place them separately, which is more flexible for users when traveling or carrying for daily use.

[0051] It is worth mentioning that the detachable connection between the external battery assembly 50 and the housing 10 is achieved by magnetic attraction between the first magnetic member 13 and the second magnetic member 51. The magnetic connection provides a quick and convenient connection method without complicated operations or additional tools. Just bring the two parts close together to automatically adsorb them together, making assembly and disassembly faster.

[0052] Reference Figure 3 and Figure 4 In one embodiment, a first conductive contact 14 is installed on the housing 10, the first conductive contact 14 is electrically connected to the air pump 20, and the first conductive contact 14 is exposed on the outer surface of the housing 10; the external battery assembly 50 includes a battery compartment 52 and a battery 53 installed in the battery compartment 52, and a second conductive contact 54 and a second magnetic member 51 are installed on the battery compartment 52, the second conductive contact 54 is electrically connected to the battery 53, and the second conductive contact 54 is exposed on the outer surface of the battery compartment 52, so that the first conductive contact 14 can be used in conjunction with the second conductive contact 54. In this way, when the first magnetic member 13 and the second magnetic member 51 are attracted to each other, the first conductive contact 14 and the second conductive contact 54 are directly in contact with each other, so that the electrical connection between the air pump 20 and the battery 53 is realized, and the battery 53 can power the air pump 20 more conveniently and quickly without complicated operations.

[0053] In this embodiment, the battery compartment 52 can provide protection for the battery 53 to prevent damage to the battery 53. The battery compartment 52 includes a cover plate and a shell, the second conductive contact 54 and the second magnetic member 51 are both arranged on the cover plate, and the shell is covered on the cover plate to enclose a space for accommodating the battery 53. The connection between the cover plate and the shell can be threaded or snap-fit, which is not limited here.

[0054] Reference Figure 3 In one embodiment, a mounting groove 15 is provided on the outer surface of the housing 10, and the first conductive contact 14 and the second magnetic member 51 are both provided at the bottom of the mounting groove 15. The battery compartment 52 is provided with a boss 521, and the first conductive contact 14 and the second magnetic member 51 are provided on the boss 521. The mounting groove 15 is adapted to the outer contour of the boss 521 to limit the mounting boss 521. Such a configuration makes it more convenient for the user to connect the external battery assembly 50 with the housing 10 and the connection can be more secure. Specifically, the outer periphery of the mounting groove 15 can facilitate the user to align. When connecting, it is only necessary to roughly align the outer contour of the boss 521 with the mounting groove 15, and the external battery assembly 50 can be quickly positioned and connected with the housing 10. In addition, since the boss 521 is accommodated in the mounting groove 15, the groove wall of the mounting groove 15 limits the boss 521, so that it is not easy to shift easily, and the connection reliability of the two is better.

[0055] In this embodiment, the installation groove 15 and the boss 521 are both in an arch shape to facilitate the user to identify the installation direction.

[0056] Reference Figures 2 to 4 In one embodiment, the housing 10 is further provided with an input interface 16, and the input interface 16 is electrically connected to the second conductive contact 54 and / or the air pump 20. With such a configuration, the power supply method of the nasal washer 1000 is more flexible. Specifically, the input interface 16 can be a USB interface, through which the air pump 20 can be directly powered or the battery 53 can be charged, and the user can choose a suitable power supply method according to actual needs. Moreover, the advantage of such a design is that when the battery 53 is low in power, it can be directly powered through the input interface 16 to ensure that the nasal washer 1000 continues to operate and extend its use time.

[0057] Reference Figure 5 In one embodiment, the housing 10 includes a base 17 and a liquid storage cup 18, the mounting cavity 11 is disposed in the base 17, the first magnetic member 13 is mounted on the base 17, the liquid storage cup 18 is detachably connected to the base 17, the liquid storage cavity 12 is disposed in the liquid storage cup 18, and the nozzle seat 30 is covered at the mouth of the liquid storage cup 18. With such a configuration, the detachable liquid storage cup 18 makes cleaning and maintenance more convenient. The user can easily remove the liquid storage cup 18 for cleaning, avoid residue or bacterial growth, and keep the nasal washer 1000 hygienic.

[0058] Preferably, in this embodiment, the liquid storage cup 18 can be made of a transparent material to facilitate the user to observe the remaining amount of the nasal wash solution in the liquid storage cup 18, so that the user can add it in time; further, the capacity scale number can be marked on the outside of the transparent liquid storage cup 18, for example, 5ml, 10ml, and 15ml are marked in sequence, so that the user can accurately add the amount of nasal wash solution according to the needs, ensure use on demand, and avoid waste.

[0059] There are many ways to detachably connect the liquid storage cup 18 and the base 17, see Figures 5 to 7 In the present application, a circular slot 171 is provided on the base 17, and a connecting platform 181 is provided on one side of the liquid storage cup 18 facing the circular slot 171; the outer contour of the connecting platform 181 is adapted to the circular slot 171, and a limiting protrusion 181a is provided on the outer peripheral surface of the connecting platform 181; a limiting groove 172 is provided on the groove wall of the circular slot 171, and the limiting groove 172 includes a receiving portion 172a and a limiting portion 172b, the receiving portion 172a is connected to the end of the base 17 facing the liquid storage cup 18, and the limiting portion 172b is connected to the position of the receiving portion 172a away from the liquid storage cup 18, and extends in the circumferential direction of the circular slot 171 to limit the installation of the limiting protrusion 181a. With such a configuration, the liquid storage cup 18 can be locked or unlocked with the base 17 by rotating, and the connection operation is more convenient and efficient.

[0060] Specifically, when the connecting platform 181 is inserted into the circular slot 171, the limiting protrusion 181a is inserted into the accommodating portion 172a and moves to the end of the accommodating portion 172a away from the liquid storage cup 18. The accommodating portion 172a can guide the limiting protrusion 181a to a predetermined position, so that the limiting protrusion 181a can subsequently cooperate with the limiting portion 172b. The connecting platform 181 is adapted to the circular slot 171 to facilitate its rotation along the circumference of the circular slot 171. The limiting protrusion 181a is transferred to the limiting portion 172b, and the limiting portion 172b limits the limiting protrusion 181a, so that the liquid storage cup 18 is firmly connected to the base 17.

[0061] Furthermore, the nasal washer 1000 further includes a positioning structure 60, which includes a clamping block 61 and a clamping groove 62. The clamping block 61 is disposed on one of the limiting protrusion 181a and the limiting portion 172b, and the clamping groove 62 is disposed on the other of the limiting protrusion 181a and the limiting groove 172. When the limiting protrusion 181a is accommodated in the limiting portion 172b, the clamping block 61 is clamped with the clamping groove 62. In this way, the clamping block 61 and the clamping groove 62 can prevent the limiting protrusion 181a from returning to the accommodating portion 172a, so as to further improve the reliability of the connection between the liquid storage cup 18 and the base 17.

[0062] Preferably, in the present application, the clamping block 61 has an arcuate surface 611 , and the arcuate surface 611 has a small contact area with the limiting portion 172 b of the limiting groove 172 , which can facilitate its insertion into the clamping groove 62 for clamping.

[0063] Reference Figure 8 and Fig. 9 In one embodiment, the liquid storage cup 18 is also provided with a waste liquid chamber 182, which is used to collect waste liquid after cleaning the nasal cavity. The waste liquid chamber 182 is separated and arranged on one side of the liquid storage chamber 12; the nozzle seat 30 includes a connecting seat 31 and a first hollow cone 32 arranged in the center of the connecting seat 31, and the connecting seat 31 is covered at the cup mouth of the liquid storage cup 18. The top surface of the first hollow cone 32 is provided with a spray port 321, and the spray port 321 is connected with the nasal washing structure 40 so that the nasal washing liquid can be sprayed from the spray port 321 to act on the user. A collecting port 33 is provided on the connecting surface of the connecting seat 31 and the first hollow cone 32, and the collecting port 33 is connected with the waste liquid chamber 182. With such arrangement, the waste liquid ejected by the user after nasal washing falls onto the inclined surface of the first hollow cone 32 by its own gravity. The inclined surface of the first hollow cone 32 can drain the waste liquid to the collection port 33 and smoothly flow into the waste liquid cavity 182, so that the user can easily pour out the waste liquid and clean the waste liquid cavity 182, thereby maintaining the cleanliness of the entire nasal wash device 1000 and improving the user experience.

[0064] Reference Figure 8 and Fig.10 In one embodiment, the nasal washing structure 40 includes a second hollow cone 41 and a third hollow cone 42. The second hollow cone 41 is arranged in the liquid storage cavity 12, and the third hollow cone 42 is sleeved on the second hollow cone 41. The top surface of the second hollow cone 41 is provided with an air inlet 411 connected to the air pump 20, and the third hollow cone 42 is provided with an air outlet 421 connected to the air inlet 411. The air inlet 411 and the air outlet 421 are arranged opposite to each other, and the air outlet 421 is connected to the nozzle seat 30. The outer wall of the second hollow cone 41 and the inner wall of the third hollow cone 42 are spaced apart to form a guide channel 43. One end of the guide channel 43 is connected to the liquid storage cavity 12, and the other end of the guide channel 43 is connected to the air inlet 411 and the air outlet 421. With such arrangement, the air pump 20 generates compressed air to generate negative pressure between the air inlet 411 and the guide channel 43, sucking up the nasal wash liquid to flow from the guide channel 43 to the air outlet 421, and then sprayed out from the spray port 321, thereby achieving the nasal wash function.

[0065] Specifically, the second hollow cone 41 is disposed at the center of the liquid storage cup 18 and is integrally formed with the liquid storage cup 18 to facilitate manufacturing and reduce the number of parts. The third hollow cone 42 is sandwiched between the first hollow cone 32 and the second hollow cone 41 to facilitate assembly and provide a stable connection.

[0066] Preferably, in the present application, the bottom of the liquid storage cup 18 is in an inverted cone shape, and the bottom end of the second hollow cone 41 is located at the bottom of the liquid storage cup 18, so that the nasal wash liquid can always be at one end of the guide channel 43 surrounded by the second hollow cone 41 and the third hollow cone 42, which is convenient for the nasal wash liquid to be sucked away and the nasal wash liquid can be fully utilized.

[0067] Reference Figure 8 and Fig.11 In one embodiment, a partition plate 183 is provided inside the liquid storage cup 18, and the partition plate 183 is arranged between the waste liquid chamber 182 and the liquid storage chamber 12. A slot 311 is provided on the side of the nozzle seat 30 facing the liquid storage cup 18, and the partition plate 183 is at least partially accommodated in the slot 311. When the nozzle seat 30 is covered on the liquid storage cup 18, the partition plate 183 is accommodated in the slot 311 to limit and fix the nozzle seat 30 to prevent the nozzle seat 30 from rotating relative to the liquid storage cup 18. Since the nozzle seat 30 is in direct contact with the user's nostrils, the advantage of this design is that the nozzle seat 30 cannot rotate relative to the liquid storage cup 18, which means that the nozzle seat 30 will not rotate and rub against the nostrils, so as to ensure the user's comfort during the nasal washing process. Specifically, the slot 311 is arranged on the connecting seat 31, so that when the connecting seat 31 is covered on the liquid storage cup 18, the slot 311 can be quickly aligned and engaged with the partition plate 183.

[0068] In addition, the nozzle seat 30 cannot rotate relative to the liquid storage cup 18, so that the collecting port 33 will not rotate with it, which can effectively prevent the rotation of the nozzle seat 30 from causing the collecting port 33 and the waste liquid chamber 182 to be misaligned, or the collecting port 33 is directly connected to the liquid storage chamber 12, resulting in the waste liquid cannot be collected normally.

[0069] Reference Fig.10 In one embodiment, a soft rubber-coated part 34 is provided on the side of the nozzle holder 30 facing away from the liquid storage cup 18. The soft rubber-coated part 34 can provide a better touch when the nozzle holder 30 contacts the user's nostrils, making it more comfortable to use. The soft rubber-coated part 34 can also better fit the nostrils to improve the nasal washing effect.
