Description

TECHNICAL FIELD

[0001] The present application relates to the field of nasal cavity cleaning, in particular to a nasal washing device. BACKGROUND

[0002] Nasal cavity is another important channel for human body to communicate with the outside world besides oral cavity. In fact, its use frequency is much higher than oral cavity, because people need to breathe every moment. Since the environment around us is not pure. These impurities and harmful substances are blocked in the nasal cavity by the filtering function of the nasal cavity when inhaled into the human body, so that they cannot enter the lungs, but if these impurities and harmful substances are not cleaned in time and stay in the nasal cavity for a long time, more bacteria may be produced to cause nasal cavity lesions. Nasal washing device can well improve the lesions in the nasal cavity. Nasal washing device can dilute secretions. Nasal secretions of patients with rhinitis are often a lot, especially the viscous secretions which will block the nostrils. When washing the nose, the saline enters from one nostril and is discharged from the other nostril. After the secretions are washed away, the nose will be much smoother. Removing bacteria in the nasal cavity, when people come back from the outside world, they will bring back various bacteria, allergens, etc. At this time, flushing the nasal cavity with saline can improve the physiological environment inside the nose, help the nose to expel bacteria and avoid the occurrence of inflammation. Alleviating inflammatory response, saline can play a good repair role on the swelling and edema of nasal cavity tissue. Long-term adherence can also prevent the occurrence of sinusitis and nasal polyps. Most of the nasal washing devices on the market need to soak the nasal washing liquid with nasal washing salt when used. When opening the nasal washing salt, the hands will directly touch the internal salt body, which is not sanitary. And in the process of disassembling, it is easy to spill or stick on the hands, resulting in insufficient concentration of the mixed nasal washing liquid, which cannot clean the nasal cavity. The whole process of disassembling the nasal washing salt and mixing the nasal washing liquid is troublesome, and it is very tedious to repeat the operation when washing the nasal cavity multiple times, which is not efficient and convenient.

[0035] As shown in the accompanying Figures 1-12As shown, the embodiment discloses a nasal irrigator, which comprises a shell 1, a salt storage structure 2 arranged in the shell 1, and an opening structure 3 arranged in the shell 1. The opening structure opens the salt storage structure inside the shell, so that the salt in the salt storage structure mixes with the liquid inside the shell, and then cleans the inside of the nasal cavity. The use is simple and the operation is convenient. The shell 1 comprises a cover body 11 and a cup body 12 arranged below the cover body 11 and used for containing liquid. The cover body 11 is provided with a nasal tube assembly 111. The nasal tube assembly 111 is in communication with the inside of the cup body 12. The salt storage structure 2 comprises at least one salt bin 21 used for storing salt. The salt bin 21 can move away from or close to the cup body 12 along with the cover body 11. The opening structure 3 comprises a bag breaking piece 31 capable of opening the salt bin 21. The bag breaking piece 31 is arranged in the cup body 12. When the cover body 11 drives the salt bin 21 to move close to the cup body 12 and contact the bag breaking piece 31, the salt in the salt bin 21 enters the cup body 12 and mixes with the liquid. In actual application, when the nasal irrigator is not used, the liquid is contained in the cup body, and the salt in the salt bin will not enter the cup body. No matter how the nasal irrigator is placed, the liquid in it will not soak the salt in the salt bin, so that the salt can be in a sealed and dry environment without operation. When used, the salt will not be lost when not used, which is convenient and simple to operate. The bag breaking piece opens the salt bin simply and conveniently, and is efficient and convenient. When the nasal irrigator is used, the user holds the cover body to drive the salt bin to move, contacts and presses the cover body to the bag breaking piece, so that the bag breaking piece pierces the salt bin, the salt falls into the liquid in the cup, the liquid with the salt is shaken before washing the nasal cavity, and then flows out through the nasal tube assembly to clean the nasal cavity. In specific embodiments, the number of salt bins can be one or more. When there are multiple salt bins, the bag breaking piece and the salt bin positions correspond to each other during opening. When the salt bin moves relative to the bag breaking piece, both are on a movement track, so that the bag breaking piece does not pierce multiple salt bins at a time. The movement relationship between the cover body and the cup body is a pulling or pressing process. The salt bin moves away from or close to the bag breaking piece along with the cover body during the process, the bag breaking piece breaks the salt bin, and then the salt mixes with the liquid.

[0036] As an embodiment of the present application, wherein the salt storage structure 2 further comprises a connecting piece 22 capable of being fixed with the cover 11 and driving the salt bin 21 to move with the cover 11, a fixing plate 23 for fixing the salt bin 21 and being connected with the connecting piece 22, the salt bin 21 is arranged on the fixing plate 23 away from the connecting piece 22, the connecting piece 22 is connected with the salt bin 21 away from the cover 11, when the connecting piece 22 drives the salt bin 21 to move towards the cup 12 and contact with the bag breaking piece 31, the salt in the salt bin 21 enters the cup 12 and mixes with the liquid. The connecting piece connects the salt bin with the cover, which ensures that the salt bin can move with the cover when the cover is moved. In actual application, one end of the connecting piece is fixed with the cover, and the other end is connected with the fixing plate for fixing the salt bin. The size of the connecting piece needs to meet the requirement that when the cover moves towards the cup and the end of the salt bin away from the fixing plate contacts with the bag breaking piece, the cover can just close with the cup to avoid the liquid in the neti pot flowing out, and at the same time, the salt can enter the cup and mix with the liquid smoothly. In specific embodiments, the number of salt bins can be not only one, but also multiple. Multiple salt bins can be fixed at the lower end of the fixing plate, which ensures that each salt bin can contact with the bag breaking piece and break the bag, and the salt in the salt bin can mix with the liquid in the cup. In specific embodiments, the fixing plate and the connecting piece are fixedly connected, and the connecting piece drives the salt bin to move. In another embodiment, the fixing plate and the connecting piece are detachably connected, and the fixing plate drives the salt bin to be detachable relative to the connecting piece, which can be replaced for convenient use.

Part of the structure or the whole of the salt bin can be placed in the mounting member, the mounting base is sealingly and fixedly connected with the opening end side wall of the cup, in the specific embodiment, the mounting base is fixed with the side wall of the cup by ultrasonic fusion. The containing base arranged below the mounting base is arranged deep into the cup, the breaking member is arranged at the bottom of the containing base, the salt in the salt bin enters the liquid through the discharging passage at the bottom of the containing base, in the specific embodiment, the diameter of the discharging passage is greater than or equal to the diameter of the salt bin, so that the salt in the salt bin can enter the liquid in the cup smoothly, avoiding the salt residue, and ensuring that the salt in the salt bin enters the liquid completely after the salt bin is broken. In the specific embodiment, the breaking member is arranged at the moving direction of the single salt bin, and the salt can directly enter the cup through the discharging passage after the salt bin is broken by the breaking member, in the case of multiple salt bins, the positions of the salt bins need to be adjusted to ensure that the breaking end of the salt bin, the breaking member and the discharging passage are in the same straight line in the moving direction of the salt bin.

In a specific embodiment, the shape of the fixed plate is circular, and each salt bin is arranged circumferentially at the lower end of the fixed plate. The circular fixed plate can ensure that the sizes of each salt bin are consistent, so that the internal salt body capacity reaches a unified standard, and can also maximize the number of salt bins arranged at the lower end of the fixed plate, increase the use frequency, and be more convenient. In addition to the most preferred circular shape, the shape of the fixed plate can also be any other shape, not limited to circular. In a specific embodiment, each salt bin is arranged circumferentially around the lower end of the fixed plate, and a gap is arranged between the initial salt bin and the last salt bin. This gap is the placement channel. The placement channel is used to accommodate the broken bag piece when the salt bin is not needed. The neti pot has only a use state or a non-use state. When needed, the salt bin is aligned with the broken bag piece and moved relatively to achieve broken bag. When not needed, the broken bag piece is placed in the placement channel to avoid damaging the salt bin and causing salt body waste. In a specific embodiment, the side wall of the salt bin is made of a relatively hard material to better withstand stress when the cover is moved and contacts the broken bag piece, and to open the closure. The closure can be made of a waterproof and moisture-proof material, such as a PE film. In a specific embodiment, the sealing piece is made of a soft material such as silicone or rubber. The sealing piece is used to seal the liquid in the cup to prevent the liquid from leaking out between the fixed plate and the mounting seat. In actual application, when the neti pot is not used, the broken bag piece is placed in the placement channel, the cup cover drives the salt bin to move towards the cup body, the sealing piece abuts and seals with the mounting seat to prevent the liquid in the cup from flowing out through the gap between the fixed plate and the mounting seat. When the neti pot is used, the salt bin needs to be aligned with the broken bag piece first, and then the salt bin is driven to move towards the broken bag piece until the sealing piece abuts with the mounting seat and the broken bag piece breaks the salt bin. The salt body mixes with the liquid for use.

[0039] As an embodiment of the present application, wherein the breaking piece 31 is arranged on the bottom of the accommodating seat 322, the cover 11 comprises an upper cover 112 and a lower cover 113 arranged on the lower end of the upper cover 112, the upper cover 112 is capable of moving away from the lower cover 113, the end of the lower cover 113 away from the upper cover 112 is capable of being detachably connected with the cup body 12, the connecting piece 22 is capable of being fixed with the upper cover 112, the upper cover 112 is capable of moving the salt bin 21 away from or close to the accommodating seat 322, when the upper cover 112 moves the salt bin 21 away from the accommodating seat 322, the upper cover 112 is capable of rotating the salt bin 21 relative to the lower cover 113; when the upper cover 112 moves the salt bin 21 corresponding to the longitudinal position of the breaking piece 31, the upper cover 112 moves the salt bin 21 to close to the accommodating seat 322, the breaking piece 31 pierces the closing piece 25, and the salt body in the salt bin 21 enters the cup body 12 to mix with the liquid. The upper cover and the lower cover can be separated from each other, and the lower cover is connected with the cup body. In an embodiment, the lower cover and the cup body can be detachably connected. Through the detachable connection between the lower cover and the cup body, the cup body can be conveniently cleaned, or the liquid mixed with the salt body in the cup can be replaced. The connecting piece is fixed inside the upper cover, and the connecting piece is driven by the upper cover to drive the salt bin during the movement of the upper cover relative to the lower cover. The salt bins are arranged circumferentially at the lower end of the fixed plate. In actual application, the upper cover drives the salt bin to rotate inside the lower cover. Through the rotation of the upper cover, the multiple salt bins arranged circumferentially at the lower end of the fixed plate can be opened in turn. Specifically, the upper cover drives the salt bin to move away from the breaking piece, rotates by a certain angle to make the salt bin, the breaking piece and the discharging channel on the same movement track, moves close to the breaking piece to make the breaking piece pierce the closing piece, so that the salt body enters the cup body through the discharging channel to realize the mixing of the salt body and the liquid.
