Abstract
Description
Technical Field
[0001] This utility model relates to the field of aromatherapy technology, specifically a handheld aromatherapy tube. Background Technology
[0002] Current handheld aromatherapy devices generally adopt an integrated design of the tube and handheld part. The air intake structure is usually located on the side wall of the tube near the handheld part, with several through-holes for air introduction. The outer casing assembly typically uses a threaded connection to the tube, and opening and closing are controlled by rotation. These devices are mainly used for personal aromatherapy inhalation, relying on the wick to absorb the aromatherapy liquid and the airflow to carry volatile substances. During use, the user must hold the device and place the top of the tube over their mouth and nose to inhale the gas. In a typical structure, the bottom of the tube has an open cavity to accommodate the wick, and the airflow channel extends along the tube's axis to the wick area.
[0003] In the existing technology, the close proximity of the air intake and the handheld part can easily lead to fingers blocking or contaminating the air intake area during operation, affecting air cleanliness; the threaded outer cover requires multiple rotation operations to complete the installation and removal, which is not convenient in emergency use scenarios, and long-term use can easily lead to seal failure due to thread wear.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1 to 4This utility model provides a technical solution: a handheld aromatherapy tube, comprising: a tube body 1, an outer shell sleeve 2, a mounting base 3, an outer shell bottom cover 4, a dust cover 5, and a core rod 6. The bottom end of the tube body 1 is open; the outer shell sleeve 2 is fitted onto the outer side of the outer wall of the tube body 1; the top end of the mounting base 3 has a concave structure and is located at the bottom of the tube body 1; the outer shell bottom cover 4 is fitted onto the outer side of the outer wall of the mounting base 3, and its top end is connected to the outer shell sleeve 2; the dust cover 5 is detachably connected to the outer shell sleeve 2 by pressing and is fitted onto the outer side of the outer wall of the tube body 1; the core rod 6 is located inside the tube body 1.
[0019] It should be noted that when the dust cover 5 separates it from the inner sleeve 2 of the outer shell, the bottom cover 4 of the outer shell serves as a grip. The user holds the bottom cover 4 and places the top of the tube at the nostril. External air enters through the airflow channel of the tube and flows upward along the gap between the outer wall of the tube and the inner sleeve 2 of the outer shell. After the airflow enters the tube cavity through the opening at the bottom of the tube 1, it comes into contact with the aromatherapy liquid impregnated on the surface of the core rod 6. The mixed gas carrying aromatherapy molecules is inhaled into the nasal cavity through the opening at the top of the tube. After use, the dust cover 5 is pressed back to the top of the inner sleeve 2 of the outer shell. The dust cover 5 and the inner sleeve 2 of the outer shell can be sealed and protected by an elastic snap-fit structure. The core rod 6 can adsorb the aromatherapy liquid through capillary action.
[0020] Among them, the outer shell bottom cover 4, the outer shell middle cover 2 and the dust cover 5 can be made of electroplated aluminum or plastic shell. Electroplated aluminum improves the aesthetics of this device, while plastic shell reduces production costs. The core rod 6 can be made of cotton core or sponge.
[0021] In some examples, further, a number of partition strips 7 are provided on the lower part of the outer side of the outer wall of the tube body 1. The partition strips 7 are arranged in a circular array and are closely connected to the inner side of the outer wall and the inner side of the inner sleeve 2 of the outer shell.
[0022] It should be noted that the partition strip 7 divides the annular gap into multiple independent airflow channels. The outer wall of each partition strip 7 is in close contact with the inner wall of the inner sleeve 2 of the outer shell to form a radial seal. Under the action of negative pressure, the air rises along the axial airflow channels formed by each partition strip 7 and is finally drawn out from the top of the tube body 1.
[0023] In some examples, the mounting base 3 has a number of limiting seats 8 at the bottom of its concave structure. The limiting seats 8 overlap with the bottom end of the tube body 1, and multiple airflow channels are formed between the dividing strips 7 and the limiting seats 8.
[0024] In some examples, further, multiple airflow channels include a main channel 9 extending along the axis of the tube body 1, with an air inlet 10 at the top and a flow divider 11 at the bottom.
[0025] It should be noted that external air first enters the main channel 9, which extends along the axis of the tube body 1, through the air inlet 10 at the top of the main channel 9. Under the action of negative pressure, it flows downward along the main channel 9 to the diversion chamber 11 at the bottom. Through the diversion chamber 11, it finally enters the internal space of the tube body 1 and mixes with the aromatherapy.
[0026] In some examples, the mandrel 6 is further positioned between the tube 1 and the tube 6 to form a mixing chamber 12, and the top end of the tube 1 is configured as an air intake hole 13, which is connected to the mixing chamber 12.
[0027] It should be noted that after the airflow distributed by the diversion chamber 11 enters the tube body 1, it is mixed in the mixing chamber 12 formed by the core rod 6 and the inner wall of the tube body 1. During the upward process, the airflow makes full contact with the aroma liquid adsorbed by the core rod 6. The aroma molecules continue to volatilize and diffuse under the action of the airflow. The mixed aroma gas gathers at the air inlet 13 at the top of the tube body 1 to form a stable air column. It is evenly inhaled into the nasal cavity through the negative pressure. The mixing chamber 12 ensures that the volatile substances of the aroma liquid and the air are fully mixed, while maintaining the stability of the airflow.
[0028] This device features an extended handheld portion, a shortened air intake position, and an upper side air intake location away from hand contact. The press-type outer cover can be easily and quickly opened with a gentle pull.
[0029] In some examples, the top of the inner sleeve 2 is provided with a slope, and the interior of the dust cover 5 is provided with plastic fittings that are in direct contact with the outer wall of the inner sleeve 2.
[0030] It should be noted that when the dust cover 5 is assembled with the inner sleeve 2 of the outer shell by pressing, the plastic parts inside the dust cover 5 slide along the slope at the top of the inner sleeve 2 of the outer shell, and the slope guides the plastic parts to produce radial elastic deformation; at the end of the pressing stroke, the plastic parts form an interference contact with the outer wall of the inner sleeve 2 of the outer shell. When disassembling, an axial tensile force is applied to make the plastic parts slide in the opposite direction along the slope, and the restoring force generated by the elastic deformation causes the snap-fit structure to disengage.
