Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to a waterproof handheld atomizer. Background Technology

[0002] A nebulizer is used to atomize a test solution. It is a crucial component of an atomization system, and its performance significantly impacts the precision of the measurement and reduces chemical interference. Therefore, nebulizers are required to produce stable sprays, fine and uniform droplets, and high atomization efficiency.

[0003] Handheld nebulizers are used for home medical or personal protective humidification to change the humidity of the air.

[0004] Existing atomizers are composed of multiple parts after production. These parts are assembled to form a complete handheld atomizer. However, in order to connect the circuit board to the atomizing plate, existing handheld atomizers directly solder one end of the pin to the circuit board and pre-drill holes in the outer shell. During installation, the pin is inserted into the hole. However, directly inserting it into the hole of the outer shell cannot form a tight connection with the outer shell. This can cause water from the water tank to leak onto the circuit board, causing a short circuit and increasing the cost of use.

[0005] Furthermore, existing handheld atomizers require the pins on the circuit board to be inserted into pre-drilled holes in the outer casing during installation, which is time-consuming, laborious, and reduces work efficiency. Summary of the Invention

[0006] To address the aforementioned problems in existing technologies, a waterproof handheld atomizer is provided.

[0007] The specific technical solution is as follows:

[0008] Design a waterproof handheld atomizer, including a main body, an atomizing plate, and a spring-loaded pin. The top of the main body is connected to a main body cover by a snap-fit ​​mechanism. A water tank is opened inside the main body cover. A lamp post is connected to the inside of the main body cover by fasteners. The middle part of the spring-loaded pin is fixedly connected to one side of the main body cover. One end of the spring-loaded pin is connected to a circuit board, and the other end of the spring-loaded pin is provided with a pin contact. A water tank pin is fixedly connected to the bottom of the water tank, and one end of the water tank pin is provided with a water tank contact.

[0009] Preferably, the water tank is provided with a cover plate on top, one end of the cover plate is connected to the water tank by a hinge, the other end of the cover plate is connected to the water tank by a buckle, and the edge of the cover plate is connected to a rubber strip by adhesive.

[0010] Preferably, a mist nozzle is provided on one side of the water tank, and an atomizing plate is connected inside the mist nozzle by a fastener. The atomizing plate is connected to the end of the water tank pin away from the water tank contact point.

[0011] Preferably, the top of the main body cover is connected to the inner wall of the bottom of the water tank by a snap-fit ​​mechanism, the spring pins penetrate the main body cover, and the spring pins are symmetrically distributed.

[0012] Preferably, a battery compartment is provided inside the main body, and a circuit board is provided on one side of the battery compartment. The circuit board is connected to the inner wall of the main body by fasteners.

[0013] Preferably, the outer wall of the main body is connected to the display screen by fasteners, the display screen is connected to the circuit board by wiring, a switch button is provided below the display screen, the switch button is connected to the main body by fasteners, and the switch button is connected to the circuit board by fasteners.

[0014] Preferably, the water tank ejector pin is connected to the ejector pin contact via the water tank contact, and the water tank ejector pin and the spring ejector pin are mutually attached to each other via the water tank contact and the ejector pin contact.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] 1. By incorporating spring-loaded pins and water tank pins, and fixing the spring-loaded pins to the main body cover before assembly, a better seal is achieved between the spring-loaded pins and the cover, isolating the bottom of the water tank from the interior of the main body. The spring-loaded pins at the connection point between the spring-loaded pins and the main body cover are thinner, while the spring-loaded pins on both sides of the connection point are larger, effectively sealing and blocking the gaps at the connection. This prevents water from leaking through the connection between the pins and the main body cover and onto the circuit board, which could damage the circuit board if holes are pre-drilled in the housing and the pins are inserted into them. This demonstrates the safety of the device and reduces operating costs.

[0017] 2. By incorporating spring-loaded pins and water tank pins, when assembling the handheld atomizer, simply move the main body top cover to the top of the main body, engaging the top cover and the main body. Then, move the water tank so that its bottom engages with the top cover. Since the spring-loaded pin is connected to the main body top cover, one end of the spring-loaded pin is connected to the circuit board, and the other end connects to the water tank pin's water tank contact point, thus connecting the water tank and the circuit board inside the main body to complete the assembly. This simple and quick process effectively improves work efficiency. Attached Figure Description

[0025] 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.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Reference Figure 1-5A waterproof handheld atomizer includes a main body 1, an atomizing plate 6, and a spring-loaded pin 14. The top of the main body 1 is connected to a main body cover 4 by a snap-fit ​​mechanism. A water tank 2 is provided inside the main body cover 4. A lamp post 12 is connected to the inside of the main body cover 4 by fasteners. The middle of the spring-loaded pin 14 is fixedly connected to one side of the main body cover 4. One end of the spring-loaded pin 14 is connected to a circuit board 16, and the other end of the spring-loaded pin 14 has a pin contact 10. A water tank pin 15 is fixedly connected to the bottom of the water tank 2. One end of the water tank pin 15 has a water tank contact 13. By fixing the spring-loaded pin 14 to the main body cover 4 before assembly, a better seal can be achieved between the spring-loaded pin 14 and the cover, isolating the bottom of the water tank 2 from the interior of the main body 1. This prevents water from leaking through the connection between the pin and the main body cover 4 into the circuit board 16 and causing damage to the circuit board 16 if a hole is pre-drilled in the housing and the pin is inserted into the hole. This demonstrates the safety of the device and reduces the cost of use.

[0029] Furthermore, the top of the water tank 2 is provided with a cover plate 3. One end of the cover plate 3 is connected to the water tank 2 via a hinge, and the other end of the cover plate 3 is connected to the water tank 2 via a buckle. The edge of the cover plate 3 is connected to a rubber strip 9 by adhesive. The rubber strip is used to make the cover plate 3 and the water tank 2 better sealed. The cover plate 3 can be opened and closed by the buckle. The lamp post 12 on the main body top cover 4 can illuminate the inside of the water tank 2, making it easy for users to see when using it at night. At the same time, the lamp post 12 can emit light of different colors.

[0030] Furthermore, a mist nozzle 5 is provided on one side of the water tank 2. The mist nozzle 5 is connected to an atomizing plate 6 by fasteners. The atomizing plate 6 is connected to the end of the water tank pin 15 away from the water tank contact 13. The atomizing nozzle is used to guide the water mist after it is atomized by the atomizing plate 6. The atomizing plate 6 causes the water on it to drift to the outside in a mist form through its own high-frequency vibration.

[0031] Furthermore, the top of the main body cover 4 is connected to the bottom inner wall of the water tank 2 by a snap-fit ​​mechanism. The spring pins 14 penetrate the main body cover 4 and are symmetrically distributed. The water tank 2 is made of transparent plastic and is made of polycarbonate (PC) material, so that users can see the amount of water remaining without opening the cover 3.

[0032] Furthermore, a battery compartment 11 is provided inside the main body 1, and a circuit board 16 is provided on one side of the battery compartment 11. The circuit board 16 is connected to the inner wall of the main body 1 by fasteners. The battery compartment 11 is located on one side of the circuit board 16. The battery compartment 11 is used to hold AA batteries to power the components. When installing the spring pin 14 and the main body top cover 4, glue can be applied to the connection to seal it. At the same time, the connection between the plastic main body top cover 4 and the spring pin 14 can be melted and connected to the spring pin 14.

[0033] Furthermore, the outer wall of the main body 1 is connected to the display screen 7 by fasteners, the display screen 7 is connected to the circuit board 16 by wiring, and a switch button 8 is provided below the display screen 7. The switch button 8 is connected to the main body 1 by fasteners and to the circuit board 16 by fasteners. The switch button 8 is used to control the waterproof handheld atomizer.

[0034] Furthermore, the water tank ejector pin 15 is connected to the ejector pin contact 10 through the water tank contact 13. The water tank ejector pin 15 and the spring ejector pin 14 are attached to each other through the water tank contact 13 and the ejector pin contact 10. One end of the spring ejector pin 14, the ejector pin contact 10, is used to attach and connect with the water tank ejector pin 15, so that the atomizing plate 6 can be connected to the circuit board 16. The spring ejector pin 14 has a certain elasticity, which is an existing structure.

[0035] Working principle: When using this device, firstly, before assembly, fix the spring pin 14 to the main body top cover 4. This ensures a better seal between the spring pin 14 and the top cover, isolating the bottom of the water tank 2 from the interior of the main body 1. The spring pin 14 at the connection point between the spring pin 14 and the main body top cover 4 is thinner, while the spring pins 14 on both sides of the connection point are larger. This seals and blocks the gap at the connection point, preventing the need for pre-drilled holes in the housing. When the pin is inserted into the through hole, water will flow through the space between the pin and the main body top cover 4. When leakage occurs at the connection point onto the circuit board 16, and the handheld atomizer needs to be assembled, move the main body top cover 4 to the top of the main body 1 and engage the main body top cover 4 with the main body 1. Then move the water tank 2 so that the bottom of the water tank 2 engages with the top of the main body top cover 4. Since the spring pin 14 is connected to the main body top cover 4, one end of the spring pin 14 is connected to the circuit board 16, and the other end of the spring pin 14 is connected to the water tank contact 13 of the water tank pin 15 through the pin contact 10, so that the water tank 2 and the circuit board 16 inside the main body 1 are connected together, and the work can be completed.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
