Description

Technical Field

[0001] The utility model relates to the technical field of spray bottles, and particularly relates to a spray bottle for external auditory canal. Background Art

[0002] When there are traumas or damages in the external auditory canal, spraying medicine into the external auditory canal is a common and effective treatment method. This treatment method usually requires the use of a spray bottle to spray the medicine on the trauma of the external auditory canal to promote the healing of the trauma. However, there are some problems in the actual use of the existing spray bottles for the ear canal. First of all, if the spray nozzle is placed outside the ear canal, the atomized liquid medicine is easy to spray onto other facial parts, which will not only cause waste of the medicine, but also may cause unnecessary irritation or damage to other facial parts. Secondly, if the spray nozzle extends into the ear canal, the friction between the spray tube and the ear canal is easy to cause ear canal injury and increase the discomfort of the patient. In addition, due to the gap between the spray tube and the ear canal, the liquid medicine is easy to overflow from the ear canal and adhere to other facial parts, resulting in waste of the medicine or adverse effects on the face.

[0003] For example, in the patent with the Chinese patent authorization announcement number CN210131246U and the name of "an external ear spray bottle", the external ear spray bottle includes a bottle body and a spray head installed on the bottle body. The spray head includes a spray tube, and the spray tube is a flexible hose that can be bent arbitrarily; a sealing head is provided at the end of the spray tube, and a spray hole is opened on the sealing head; a first suction tube is located in the bottle body and is communicated with the spray tube, and a cavity is provided at the bottom end of the first suction tube; a second suction tube is arranged on the cavity and penetrates the bottom of the cavity, and a counterweight block with a plurality of liquid suction holes is fixedly connected to the bottom of the second suction tube. The disadvantage is that when in use, the spray tube extends into the ear canal, and the liquid medicine is easy to overflow from the ear canal and thus adhere to other facial parts, resulting in waste of the medicine or damage to other facial parts. Summary of the Utility Model

[0004] Aiming at the deficiencies, the purpose of the utility model is to provide a spray bottle for external auditory canal, which can avoid the liquid medicine from overflowing from the ear canal, improve the treatment effect, reduce the discomfort of the patient, and make the spraying medicine treatment of the external auditory canal safer and more effective.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A spray bottle for external auditory canal, including a bottle body and a push-type spray head. One end of the push-type spray head close to the bottle body is provided with a liquid inlet tube that can extend into the bottle body. One side of the push-type spray head is rotatably connected with a spray tube. The liquid inlet tube is communicated with the spray tube. A spray hole is provided at the end of the spray tube far from the push-type spray head, and an ear cap is sleeved at the spray hole. The ear cap is detachably connected to the spray tube.

[0006] In this technical solution, the bottle body is combined with a push - type nozzle. One end of the nozzle is equipped with a liquid inlet pipe that can extend deep into the bottle body, ensuring the smooth suction of the liquid medicine. The side of the push - type nozzle is connected to a spray pipe through a rotational connection. The spray pipe is closely connected to the liquid inlet pipe, forming a complete liquid medicine transmission channel. The end of the spray pipe is provided with spray holes and is covered with an ear cap. The ear cap can closely fit the patient's ear canal, effectively preventing the liquid medicine from overflowing from the ear canal after being sprayed, so as to ensure that the liquid medicine can fully act on the affected area and significantly improve the treatment effect. At the same time, the fitting design of the ear cap also greatly reduces the discomfort of the patient during the treatment process, making the external ear canal spraying treatment safer and more effective. The design of the ear cap enables the nozzle to accurately insert into the ear hole during use, providing a convenient positioning function for the user, ensuring that the spray can accurately act on the external ear canal area, and improving the accuracy and convenience of use. The human ear canal is relatively short. If the nozzle is inserted too deep, it may damage the external ear canal. The presence of the ear cap plays an important limiting role. It limits the insertion depth of the nozzle, preventing potential injuries caused by excessive insertion. At the same time, when pressing the nozzle, the impact force generated by the spray may also cause damage to the eardrum. The limiting function of the ear cap effectively reduces this risk. For some patients with external ear diseases, they may be accompanied by eardrum perforation or damage. Without the limitation of the ear cap, the nozzle may be inserted too deep, resulting in the liquid medicine being sprayed into the middle ear through this perforation, increasing the risk and possibility of middle ear damage. The presence of the ear cap provides additional protection for such patients, reducing the risk of the liquid medicine entering the middle ear by mistake and ensuring the safety and effectiveness of the treatment.

[0007] The present utility model is further configured as follows: A swivel joint is provided between the push - type nozzle and the spray pipe, and a connecting rotating shaft is provided inside the swivel joint. The setting of the swivel joint between the push - type nozzle and the spray pipe enables the spray pipe to rotate freely by 360 degrees, providing great flexibility and convenience for the user. No matter what angle or position the patient's external ear canal is in, the spray pipe can be easily adjusted to the optimal spraying angle to ensure that the liquid medicine can be accurately sprayed, thereby effectively improving the treatment effect and bringing a more comfortable treatment experience to the patient.

[0008] The present utility model is further configured as follows: The push - type nozzle successively includes a button, a connecting part, and a combining part from top to bottom, and the cross - sectional areas of the button, the connecting part, and the combining part increase in sequence. Through this setting, not only does the nozzle look more stable and beautiful in appearance, but also a more stable holding feeling and operation experience are provided. When the user is using it, the button can be pressed more easily and accurately to achieve the smooth spraying of the liquid medicine, thereby further improving the treatment effect and comfort.

[0009] The utility model is further configured as follows: a limiting protrusion is provided on the adapter, the limiting protrusion and the nozzle are located on the same side of the adapter, and the limiting protrusion is close to the outer wall of the button and is located above the connecting portion. The limiting protrusion and the nozzle are located on the same side of the adapter, so that the limiting protrusion can be close to the outer wall of the button and accurately located above the connecting portion, which not only ensures a stable connection between the nozzle and the push-type spray head, but also provides additional support and fixing, so that the user can more easily and accurately control the angle and direction of the nozzle during use, improves the overall use experience of the spray bottle, and makes the external auditory canal spray treatment more convenient and efficient.

[0010] The utility model is further configured such that: when the axis of the nozzle is parallel to the axis of the bottle body, the lower surface of the limiting protrusion abuts against the upper surface of the connecting portion. When the axis of the nozzle remains parallel to the axis of the bottle body, the lower surface of the limiting protrusion abuts against the upper surface of the connecting portion, effectively preventing accidental pressing, ensuring that only when necessary, the user can easily and accurately press the button to spray the liquid medicine after rotating the nozzle to a certain angle. Not only does it improve the convenience of use, but more importantly, it significantly enhances the safety of the spray bottle, avoids unnecessary waste of liquid medicine or potential risks caused by misoperation, and provides patients with a more secure and reliable treatment experience.

[0011] The utility model is further configured as follows: the inner wall of the joint is provided with an internal thread, the bottle mouth of the bottle body is provided with an external thread, and the internal thread is adapted to the external thread. This configuration not only ensures a tight connection between the push-type spray head and the bottle body, effectively preventing leakage of the liquid medicine, but also enables the user to easily and conveniently install and disassemble the spray head during use, thereby improving the overall use experience of the spray bottle and making external auditory canal spray treatment more convenient and efficient.

[0012] The utility model is further configured as follows: a through hole for passing the liquid inlet pipe is provided in the center of the connecting part and the joint part. This configuration not only ensures that the liquid medicine can flow smoothly from the bottle into the push-type spray head, providing a stable liquid medicine supply for the spraying process, but also makes the overall structure more compact and reasonable. When using it, the user can perform external auditory canal spraying treatment more conveniently and efficiently without worrying about problems such as poor liquid medicine supply or nozzle blockage, thereby obtaining a more comfortable and reliable treatment experience.

[0013] The present utility model is further configured as follows: The outer wall of the joint part is provided with a friction structure that facilitates screwing the push - type nozzle tightly onto or off the bottle body. With this configuration, not only can the user install or disassemble the nozzle more easily and labor - saving, but also the tight connection between the nozzle and the bottle body is ensured, effectively preventing the leakage of the liquid medicine. At the same time, the existence of the friction structure also provides a good hand feeling, enabling the user to more intuitively feel the stability of the nozzle during use, thus obtaining a more reassuring and comfortable treatment experience.

[0014] The present utility model is further configured as follows: The connecting rotating shaft is located at the upper end of the button, and the button is marked with a marking arrow. The rotating shaft is ingeniously placed at the upper end of the button, making the rotation operation of the push - type nozzle smoother and more natural, bringing a comfortable use experience to the user. In addition, the button is marked with a clear marking arrow, which ingeniously indicates the position of the spray hole, enabling the user to accurately align with the external auditory canal during use for precise spraying of the medicine, improving the overall usability of the spray bottle and making the external auditory canal spraying treatment simpler, faster, and more efficient.

[0015] The present utility model is further configured as follows: The material of the ear cap is rubber. The soft material of the ear cap also greatly reduces the discomfort of the patient during the treatment process, making the external auditory canal spraying treatment safer and more effective.

[0016] The advantages of the present utility model are: (1) The end of the spray tube is provided with a spray hole and is covered with an ear cap. The ear cap can closely fit the patient's ear canal, effectively preventing the liquid medicine from overflowing from the ear canal after being sprayed, thus ensuring that the liquid medicine can fully act on the affected area and significantly improving the treatment effect; (2) The fitting design of the ear cap greatly reduces the discomfort of the patient during the treatment process, making the external auditory canal spraying treatment safer and more effective; (3) When the axis of the spray tube is parallel to the axis of the bottle body, the lower surface of the limit protrusion abuts against the upper surface of the connecting part, effectively preventing accidental pressing.

The ear cap 42 can closely fit the patient's ear canal, effectively preventing the liquid medicine from overflowing from the ear canal after being sprayed, thereby ensuring that the liquid medicine can fully act on the affected area and significantly improving the treatment effect. At the same time, the fitting design of the ear cap 42 also greatly reduces the discomfort of the patient during the treatment process, making the external ear canal spraying treatment safer and more effective. The design of the ear cap 42 enables the nozzle to accurately insert into the ear hole during use, providing a convenient positioning function for the user, ensuring that the spray can accurately act on the external ear canal area, and improving the accuracy and convenience of use. The human ear canal is relatively short. If the nozzle is inserted too deep, it may damage the external ear canal. The presence of the ear cap 42 plays an important limiting role. It limits the insertion depth of the nozzle, preventing potential damage caused by excessive insertion. At the same time, when pressing the nozzle, the impact force generated by the spray may also cause damage to the eardrum. The limiting function of the ear cap 42 effectively reduces this risk. For some patients with external ear diseases, they may be accompanied by eardrum perforation or damage. Without the limitation of the ear cap, the nozzle may be inserted too deep, causing the liquid medicine to be sprayed into the middle ear through this perforation, increasing the risk and possibility of middle ear damage. The presence of the ear cap provides additional protection for such patients, reducing the risk of the liquid medicine accidentally entering the middle ear and ensuring the safety and effectiveness of the treatment.
