Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable handheld nebulizer. Background Technology

[0002] Currently, the most common connection methods for various portable handheld atomizers on the market are "rail + magnetic" or "rail + spring clip". That is, the liquid container is connected to the atomizer main unit using a magnetic or clip structure, and the circuit connection is achieved through conductive metal spring pins or plugs.

[0003] The rail-guided magnetic atomizer connection method relies on magnets for fixing and locking, requiring very high permanent magnet strength. Furthermore, both the liquid container and the main unit require precisely matched magnets on both sides. This results in high magnet costs, directional magnet assembly, and a complex assembly process. Excessive magnetic force requires significant force to remove or replace the liquid container, which can easily cause it to slip out during disassembly, damaging the device's structure.

[0004] If ordinary magnets are used, they are easily demagnetized, or the magnet and iron attraction is insufficient. Insufficient magnetic force can lead to improper circuit connections or poor contact; during use, they are prone to detachment.

[0005] The guide rail + spring clip type atomizer connection relies on clips for fixing and locking, resulting in a complex spring clip structure and assembly process. The spring clip connects to the main unit, creating assembly gaps that allow water to easily leak into the main unit, failing to meet the new national standard for waterproof performance of household atomizers. To meet waterproof requirements, a separate drainage channel needs to be designed for the spring clip, or an elastic sealing structure needs to be added to the clip, further increasing assembly difficulty and equipment cost.

[0006] In addition, the above two methods are inconvenient for partial replacement of consumables. For fragile liquid containers, even if there is partial damage, the whole container needs to be replaced, which is not economical. Utility Model Content

[0007] The purpose of this invention is to provide a portable handheld nebulizer that separates the liquid container structure into a container base and a liquid storage tank. While ensuring the connection strength between the liquid container and the main unit, it is easy to disassemble, clean, and replace, allowing users to change to different models of tanks according to different drug usage scenarios to meet different dosage requirements.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable handheld atomizer, comprising a main unit and a liquid container, wherein:

[0009] The top of the host has a vertical first mounting hole, the upper left side wall of the host has a horizontal second mounting hole, and a liquid container placement cavity is formed inside the host at the position directly opposite the first and second mounting holes.

[0010] The liquid container consists of a container base and a liquid storage tank;

[0011] The right half of the container base is the liquid storage section, which is a horizontally arranged cylinder. The upper part of the liquid storage section has a vertical tank mounting port with internal threads. The middle part of the liquid storage section has a liquid storage cavity. The tank mounting port is connected to the liquid storage cavity. The left side of the liquid storage cavity is connected to the liquid outlet channel. An atomizing plate is installed in the mounting groove connected to the left side of the liquid outlet channel. The atomizing plate is powered by the main unit.

[0012] The left half of the container base is a connector for connecting an atomizing mouthpiece or atomizing mask. The right end of the connector has a mist outlet, which is connected to the mounting slot of the atomizing plate.

[0013] The bottom of the liquid storage tank has a liquid outlet, and the outer surface of the liquid outlet has external threads.

[0014] The liquid storage section of the container base is installed in the liquid container placement cavity of the main unit through the second mounting hole, and the bottom of the liquid storage tank is installed in the tank installation port of the liquid storage section through the first mounting hole and threadedly connected.

[0015] The beneficial effects of this utility model are as follows:

[0016] The liquid container structure is divided into two parts: a container base and a liquid storage tank. The liquid storage section of the container base is installed inside the liquid container placement cavity of the main unit. The liquid storage tank is then screwed onto the container base and locked in place, creating an interlocking structure between the liquid container and the nebulizer main unit. This ensures the connection strength between the liquid container and the main unit while facilitating disassembly and cleaning. The container base and liquid storage tank can be replaced individually, making partial replacement more economical. Furthermore, it allows users to easily replace the tank with different models to meet varying dosage requirements for different medication usage scenarios.

[0017] Furthermore, the right side wall of the liquid container placement cavity of the main unit slopes from the upper right to the lower left, causing the liquid container placement cavity to gradually narrow from top to bottom. The right end face of the liquid storage part of the container base also slopes from the upper right to the lower left, adapting to the shape and size of the liquid container placement cavity. This sloped structure can, to some extent, prevent the container base from rotating around its axial direction.

[0018] Furthermore, the outer wall of the liquid storage section of the container base is provided with a transverse guide rail groove, and the inner wall of the liquid container placement cavity of the main unit is fixedly installed or integrally formed with a guide rail that mates with the guide rail groove. The guide rail structure makes the installation of the container base smoother and the positioning more precise. After the container base is installed on the main unit, its top is completely aligned with the top, which facilitates quick and accurate installation of the liquid storage tank. Moreover, during use, the guide rail prevents the container base from rotating around its axis, further ensuring the overall stability of the device.

[0019] Furthermore, the top of the liquid storage tank has an opening, and a sealing cap is installed at the opening. The sealing cap is connected to the liquid storage tank via a flexible connecting strip. This facilitates adding liquid from the top of the liquid storage tank during use, making it more convenient to use.

[0020] Furthermore, at least one environmental communication hole is provided on the side wall of the connector of the container base. This allows for airflow compensation when the user breathes, connecting to ambient air.

[0021] Furthermore, the bottom of the liquid storage chamber of the liquid storage unit is inclined from right to left, and the bottom of the liquid outlet channel is flush with the bottom of the left side of the liquid storage chamber. This allows the liquid to automatically gather at the bottom liquid outlet channel, achieving full atomization and reducing the amount of liquid residue.

[0022] Furthermore, the specific connection method for the atomizing plate to be powered by the main unit is as follows:

[0023] A spring-loaded connector is installed on the right end face of the liquid storage section of the container base. A female connector that mates with the spring-loaded connector is installed on the right side wall of the liquid container placement cavity of the main unit. The atomizing plate is connected to the spring-loaded connector via a wire. The atomizing controller inside the main unit is connected to the female connector via a wire. Attached Figure Description

The upper part of the liquid storage section 201 has a vertical tank installation port 201a with internal threads. The middle part of the liquid storage section 201 has a liquid storage cavity 201b. The tank installation port 201a is connected to the liquid storage cavity 201b. The left side of the liquid storage cavity 201b is connected to the liquid outlet channel 201c.

[0037] The bottom of the liquid storage chamber 201b is inclined with the right side higher than the left side, and the bottom of the liquid outlet channel 201c is flush with the bottom left side of the liquid storage chamber 201b.

[0038] An atomizing plate 4 is installed in the mounting slot that connects to the left side of the liquid outlet channel 201c; the atomizing plate 4 is powered by the main unit 1.

[0039] The left half of the container base 2 is a connector 202 for connecting an atomizing mouthpiece or atomizing mask. The right end of the connector 202 has a mist outlet 202a, which is connected to the mounting groove of the atomizing plate 4. Four symmetrically arranged environmental communication holes 202b are also provided on the side wall of the connector 202.

[0040] The bottom of the liquid storage tank 3 has a liquid outlet 3a, and the outer surface of the liquid outlet 3a has external threads;

[0041] The top of the liquid storage tank 3 has an opening, and a sealing cover 5 is installed at the opening. The sealing cover 5 is connected to the liquid storage tank 3 by a flexible connecting strip 6.

[0042] The liquid storage section 201 of the container base 2 is installed in the liquid container placement cavity 1c of the main unit 1 through the second mounting hole 1b. The bottom of the liquid storage tank 3 passes through the first mounting hole 1a and is threadedly connected to the tank installation port 201a of the liquid storage section 201.

[0043] In this embodiment, the right side wall of the liquid container placement cavity 1c of the host 1 slopes from the upper right to the lower left, and the right end face of the liquid storage part 201 of the container base 2 also slopes from the upper right to the lower left, adapting to the shape and size of the liquid container placement cavity 1c. The outer wall of the liquid storage part 201 of the container base 2 is provided with two symmetrically arranged transverse guide rail grooves 201d, and two guide rails 101 that cooperate with the guide rail grooves 201d are fixedly installed or integrally formed on the inner wall of the liquid container placement cavity 1c of the host 1.

[0044] In this embodiment, the specific connection method of the atomizing plate 4 being powered by the host 1 is as follows:

[0045] A spring-loaded connector 7 is installed on the right end face of the liquid storage section 201 of the container base 2. A female connector 8 that mates with the spring-loaded connector 7 is installed on the right side wall of the liquid container placement cavity 1c of the main unit 1. The atomizing plate 4 is connected to the spring-loaded connector 7 by a wire. The wire passes through a separately formed wiring channel in the liquid storage section 201. The atomizing controller in the main unit 1 is connected to the female connector 8 by a wire.

[0046] The internal circuit structure of the atomizing controller and other components inside the main unit 1 adopts the common circuit of existing portable handheld atomizer main units, which is not within the scope of improvement of this utility model, and will not be described in detail here.

[0047] The usage and working principle of this embodiment are as follows:

[0048] First, the liquid storage section 201 of the container base 2 is passed through the second mounting hole 1b and installed in the liquid container placement cavity 1c of the main unit 1 under the guidance of the guide rail 101. Then, the bottom of the liquid storage tank 3 is passed through the first mounting hole 1a and connected to the tank installation port 201a of the liquid storage section 201 by threads.

[0049] After the container base 2 is installed in place, the spring pin of the spring pin connector 7 contacts the contact point of the female connector 8, realizing the electrical connection between the main unit 1 and the atomizing plate 4. When the main unit 1 is turned on, the atomization controller inside the main unit 1 sends an electrical signal of a specific frequency to the atomizing plate 4, driving the atomizing plate 4 to vibrate, thereby realizing the atomization of the medicine.

[0050] Add the medicine into the storage tank 3 through the top opening of the storage tank 3, and cover it with the sealing cap 5. The medicine enters the storage chamber 201b of the container base 2, passes through the liquid outlet channel 201c to reach the atomizing plate 4 and is atomized. The mist is sprayed out from the mist outlet 202a, and finally enters the external atomizing mouthpiece or atomizing mask through the connecting nozzle 202 and is inhaled by the user.
