Description

Technical Field

[0001] This invention relates to the field of disinfection machine technology, specifically to a neck-hook portable air disinfection machine. Background Technology

[0002] Traditional air disinfection equipment has long been limited by its form and adaptability to different scenarios: early floor-standing disinfection machines were only suitable for fixed places such as hospitals and laboratories due to their large size and difficulty in movement; although rope-hanging products attempted to be portable, their center of gravity design defects caused neck pain and could not accurately cover the breathing area of ​​the mouth and nose. Based on this, the portable neck-hanging air disinfection machine that can be carried with you has emerged.

[0003] In existing technologies, portable neck-hook air purifiers are typically neck-hook negative ion air purifiers. Their operating principle is mainly based on negative ion generation technology combined with a portable design. The core function is to generate negative ions through a high-voltage electric field to purify the air in the wearer's breathing area. Through a built-in high-voltage electric field (usually using corona discharge or tip discharge technology), oxygen molecules in the air are ionized and decomposed into negatively charged O₂ molecules. 2- Negative ions, or ozone, require controlled ozone production during their generation to avoid irritating the human body. Negative ions combine with positively charged particulate matter in the air, increasing their mass and causing them to settle to the ground. They can also break down the molecular structure of pollutants, decomposing them into harmless carbon dioxide and water, thus achieving a disinfection effect.

[0004] However, some high-voltage discharge technology products generate trace amounts of ozone (concentration <0.1 mg / m³) when producing negative ions. 3 (Only safe products may cause respiratory irritation or headaches with prolonged close contact.) Inferior products may even have excessive electromagnetic radiation and generate a strong static electricity when touched; low-priced products use inferior materials and may release irritating odors and toxic volatile substances such as formaldehyde when operating at high temperatures, posing a potential hazard to the respiratory system.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] This embodiment discloses a neck-hanging portable air sterilizer.

[0023] Please see Figure 1-2The portable air sterilizer with a neck strap in this embodiment includes a housing 100, which is composed of a front housing 101, a rear housing 102, a buckle cover 103, and a hanging hole head 104. The front housing 101 and the rear housing 102 are fixedly assembled by a snap-fit ​​design to form a rectangular housing with an opening at one end. The buckle cover 103 is detachably installed at the opening of the rectangular housing to form a complete housing. The hanging hole head 104 is fixedly connected to the outer corner of the housing near the buckle cover 103 for threading a rope to hang around the neck. When wearing, the buckle cover 103 faces upward, and the wearing distance can be adjusted according to the length of the rope.

[0024] Please see Figure 2-3 Inside the casing, a battery 700 and a main control circuit board 600 are fixedly installed on the upper part. The main control circuit board 600 is located above the battery 700 and is fixedly connected to it. Functional modules are located on the upper side of the main control circuit board 600, including a power button 500, an indicator light 400, and a charging interface 900 from right to left. Holes are reserved on the casing for installing the functional modules. The power button 500, indicator light 400, and charging interface 900 all extend to the outside of the casing through the holes. The power button 500 is used to control the start and stop of the sterilizer (short press: power status indication; long press > 2s: start and stop control). The indicator light 400 has four lamps to display the power level (four levels of power display). The charging interface 900 is a Type-C charging interface (5V / 1A input) for connecting a charging data cable.

[0025] It should be noted that the functions of the functional modules are not limited to the types and number of functions in this embodiment. In other embodiments, corresponding control functions can be set according to actual needs. Similarly, the control method of the power button 500 is not limited to the control method in this embodiment. In other embodiments, the control method of the power button 500 can be: a short press to control start / stop, and a long press for >2 seconds to display the power level. The number of indicator lights 400 is not limited to the four in this embodiment. In other embodiments, the number of lights can be three, five, six, etc. The type of charging interface 900 is not limited to the Type-C charging interface in this embodiment. In other embodiments, the charging interface 900 can be a USB-A interface, a Micro USB interface, a Mini USB interface, etc. In short, in other embodiments, all possible types of functions and feasible control methods for each type of function are permitted.

[0026] Please see Figure 5A release mechanism is fixedly installed on the left side inside the casing, and a disposable consumable pack 200 is detachably installed on its right side. The disposable consumable pack 200 can be loaded and unloaded by opening the cover 103, thereby connecting the disposable consumable pack 200 with the release mechanism. The release mechanism is electrically connected to the main control circuit board 600. Therefore, the start and stop of the release mechanism can be controlled by the functional modules on the main control circuit board 600.

[0027] Please see Figure 6-7 Specifically, the release mechanism includes an aeration mechanism 300, which includes an aeration device 301 and an aeration device mounting base 302. The aeration device 301 is electrically connected to the main control circuit board 600 and is installed on the far left inside the housing. Its right aeration end is provided with an aeration output end 3011. The aeration device mounting base 302 is fixedly installed inside the housing 100 and is located on the right side of the aeration device 301. It is provided with an aeration pipe 3021. The aeration output end 3011 on the right side of the aeration device 301 is inserted into the aeration pipe 3021, thereby achieving position fixation.

[0028] The disposable consumable package 200 includes a rectangular compartment 201, with a closed end at the left end, which is sealed using ultrasonic welding. A mounting boss 2041 is provided on the inner side of the microporous array plate base 204, and a mounting hole 2042 communicating with the inside and outside of the compartment 201 is formed on the mounting boss 2041. An internal microporous array plate 203 is fixedly installed inside the mounting hole 2042. An end microporous array plate 202 communicating with the inside and outside of the compartment 201 is fixedly installed at the right end of the compartment 201. The micropores on both the internal microporous array plate 203 and the end microporous array plate 202 are formed using laser micro-hole processing technology. The 20µm-level permeable pore array facilitates the slow release of gas through a certain rate. The end microporous array plate 202 is located inside the cover 103, and the cover 103 is provided with an air outlet channel, allowing the end microporous array plate 202 to communicate with the outside of the housing 100. The chamber 201 stores disinfectant, which is liquid ClO2. When the disposable consumable package 200 is installed in the housing, the aeration pipe 3021 is inserted into the mounting hole 2042. When the aeration device 301 is started, it will aerate the chamber 201. The gas passes through the internal microporous array plate 203 to reach the inside of the chamber 201 and mixes with ClO2, thereby stimulating the high-purity liquid ClO2 to generate gaseous ClO2 and releasing it from the end microporous array plate 202. The released gaseous ClO2 passes through the air outlet channel on the cover 103 and reaches the air around the human mouth and nose, thereby disinfecting and sterilizing.

[0029] Furthermore, the mounting hole 2042 is provided with a sealing ring 205 and a sealing pressure ring 206 for fixing the sealing ring 205. When the aeration pipe 3021 is inserted into the mounting hole 2042, it will be inserted into the sealing ring 205, thereby improving the connection sealing between the aeration pipe 3021 and the mounting hole 2042 and improving the aeration input effect.

[0030] It should be noted that before the disposable consumable pack 200 is installed in the housing for use, pressure-sensitive films 207 are attached to both sides of it. That is, pressure-sensitive films 207 are attached to the outer sides of the microporous array plate base 204 and the end microporous array plate 202 to seal the compartment 201 and prevent the internal disinfectant from leaking. Therefore, the pressure-sensitive films 207 on both sides must be removed before it can be installed in the housing for use.

[0031] The working principle of this embodiment is as follows: When using the portable air sterilizer with a neck strap, hang the disinfectant around your neck with the cap 103 facing upwards. Adjust the length of the strap to control the distance between the air outlet and your mouth and nose to 5-10cm. When disinfection is required, tear off the pressure-sensitive films 207 at both ends of the disposable consumable pack 200 and insert it into the casing. Insert the aeration tube 3021 into the mounting hole 2042, then put on the cap 103. Press and hold the power button 500 to start the aeration device 301 to aerate the chamber 201. The gas passes through the internal microporous array plate 203 and reaches the interior of the chamber 201 to mix with ClO2, thereby stimulating the high-purity liquid ClO2 to generate gaseous ClO2, which is released from the end microporous array plate 202. The released gaseous ClO2 passes through the air outlet on the cap 103 and reaches the air around the mouth and nose, thereby disinfecting and sterilizing, and optimizing the purification efficiency of the breathing zone. This air sterilizer can be carried with you and can purify your personal breathing zone instantly.

[0032] Example 2

[0033] This embodiment discloses a neck-hanging portable air sterilizer.

[0034] The only difference between the neck-hanging portable air sterilizer in this embodiment and the neck-hanging portable air sterilizer in Embodiment 1 is that the disposable consumable pack 200 and the release mechanism are different; the other structures are exactly the same.

[0035] Please see Figure 8-9 Specifically, the difference between the disposable consumable pack 200 in this embodiment and the disposable consumable pack 200 in embodiment 1 is that the disinfectant in the disposable consumable pack 200 in this embodiment includes agent A and agent B, which are separated by a water-soluble membrane. Agent A is the stabilizer sodium chlorite, and agent B is the activator citric acid. The two can be mixed and reacted according to the chemical reaction ratio to generate liquid ClO2.

[0036] Please see Figure 10-11 The difference between the release mechanism in this embodiment and that in Embodiment 1 is that the release mechanism in this embodiment further includes a heating mechanism 800. The heating mechanism 800 includes a first conductive copper pillar 801, a second conductive copper pillar 802, a third conductive copper pillar 803, and a fourth conductive copper pillar 804. One end of the first conductive copper pillar 801 and the second conductive copper pillar 802 are connected to the main control circuit board 600, and the other end of each pillar extends through and to the outside of the aeration device fixing base 302 and is provided with an electrical contact. The third conductive copper pillar 804... One end of each of the conductive copper pillars 3 and 4 is located inside the chamber 201 and is connected to a heating wire 805, which is a nickel-chromium wire with a resistance of 2Ω±0.5. The other end of each of them passes through and extends to the outside of the aeration device fixing seat 302 and is provided with an electrical contact. The contact of the conductive copper pillar 1 801 is connected to the contact of the conductive copper pillar 3 803, and the contact of the conductive copper pillar 2 802 is connected to the contact of the conductive copper pillar 4 804. The heating mechanism 800 is used to mix the disinfectant inside the chamber 201.

[0037] The working principle of this embodiment is as follows: When using the portable air sterilizer with a neck strap, hang the sterilizer around your neck with the cap 103 facing upwards. Adjust the length of the strap to control the distance between the air outlet and your mouth and nose to 5-10cm. When sterilization is required, remove the pressure-sensitive films 207 from both ends of the disposable consumable pack 200 and insert it into the casing. Insert the aeration tube 3021 into the mounting hole 2042. Simultaneously, connect the contacts of conductive copper pillar one 801 and conductive copper pillar three 803, and connect the contacts of conductive copper pillar two 802 and conductive copper pillar four 804. Then, put on the cap 103 and press and hold the power button 500 to start the aeration mechanism 300 and the heating mechanism 800. The nickel-chromium wire (heating wire 805) in the heating mechanism 800 is connected to the circuit and heats up to 300°C within 5 seconds, melting the water-soluble film to release the AB agent. The AB agent mixes to generate liquid ClO2. At the same time, the aeration mechanism 300 aerates the chamber 201. The gas passes through the internal microporous array plate 203 to reach the interior of the chamber 201 and mixes with ClO2, thereby stimulating the high-purity liquid ClO2 to generate gaseous ClO2 and releasing it from the end microporous array plate 202. The released gaseous ClO2 passes through the air outlet channel on the cover 103 to reach the air around the human mouth and nose, thereby disinfecting and sterilizing, and optimizing the purification efficiency of the breathing zone. This air sterilizer can be carried with you and can purify your personal breathing zone instantly.
