Description

Technical Field

[0001] This utility model belongs to the field of formaldehyde removal instrument technology, and in particular relates to an intelligent formaldehyde removal instrument. Background Technology

[0002] A formaldehyde removal device is a specialized device for removing indoor formaldehyde. It uses specific technologies such as photocatalysis, negative ions, or adsorption to decompose or adsorb formaldehyde in the air, reducing indoor formaldehyde concentration. Its advantages include targeted formaldehyde removal and real-time air purification.

[0003] Common formaldehyde removal devices often suffer from drawbacks such as sensor interference from backflow affecting detection accuracy, lack of protection against liquid intrusion, and low detection efficiency. Specifically, the formaldehyde sensor's airflow path is located in a single cavity without isolation structure, and the backflow of air after adsorption treatment can easily affect the sensor's detection accuracy. At the same time, motor vibration and airflow disturbance cause data drift. The air inlet lacks drainage design, and condensation of ambient moisture or accidental liquid intrusion can corrode the circuit or contaminate the sensor. The airflow directly impacts the sensor surface, and insufficient diffusion leads to response delay. Furthermore, the rapid flow of air results in a short detection time, making it difficult to accurately measure formaldehyde concentration. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an intelligent formaldehyde removal instrument. The problems solved are that common formaldehyde removal instruments suffer from high accuracy due to external factors, low detection efficiency, and lack of waterproof structure.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a top shell of a formaldehyde removal device, an air intake module in the middle of the top shell of the formaldehyde removal device, a drainage structure on the outside of the air intake module, and a columnar double-layer cavity at the bottom of the air intake module, wherein the top and bottom of the double-layer cavity are designed to be connected by pipes.

[0006] Furthermore, the air intake module includes an air intake nozzle and a connecting pipe fixedly connected to its bottom, and a plurality of circular holes are provided through the outer surface of the air intake nozzle.

[0007] Furthermore, the top shell of the formaldehyde removal device is connected to the air intake module by screws and clips, and the connecting pipe is connected to the double-layer cavity.

[0008] Furthermore, the double-layer cavity includes a cylindrical cavity and a horizontally arranged annular circular plate inside it. A mesh cylinder is vertically arranged at the inner diameter of the annular circular plate, and a formaldehyde sensor is installed on the annular circular plate.

[0009] Furthermore, the annular circular plate divides the cylindrical cavity into an upper detection cavity and a lower installation cavity. The cylindrical cavity is a two-part assembly structure that is sealed together. The annular circular plate is fixedly connected to the bottom of the upper cylindrical cavity assembly. The annular circular plate and the mesh cylinder are integrally injection molded, and the mesh cylinder has several through holes. The top of the mesh cylinder is fixedly connected to the top wall of the cylindrical cavity.

[0010] Furthermore, the formaldehyde sensor is electrically connected to the main control module.

[0011] Furthermore, the drainage structure includes a groove through which the connecting pipe passes in the middle, and a drainage pipe fitting is installed at the bottom of the groove.

[0012] Furthermore, the recessed height does not exceed twice the height of the air intake nozzle.

[0013] Furthermore, a connecting piece is fixedly provided on the inner side of the bottom of the top shell of the formaldehyde removal device for connecting with the cylindrical shell of the formaldehyde removal device.

[0014] Furthermore, the inner side of the cylindrical cavity at the bottom of the annular plate is used to install the air intake blade.

[0015] Furthermore, the intake blades and motor are mounted on the inner side of the cylindrical cavity via a bracket and electrically connected to the main control module.

[0016] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0017] 1. In this utility model, the annular circular plate physically isolates the detection chamber from the outside world, preventing the backflow of the exhaust gas after adsorption from interfering with the sensor and affecting the detection accuracy. The mesh cylinder extends the gas contact path and forms turbulence when the airflow diffuses through the air holes, thereby extending the sensor detection time.

[0018] 2. In this utility model, the groove and the drain pipe form a condensate drainage channel to discharge liquid in a timely manner, prevent liquid from entering the detection chamber, and reduce the failure rate.

[0019] 3. In this utility model, the columnar design of the double-layer cavity optimizes space utilization, and the annular circular plate in the middle for isolation also serves as a sensor support, reducing additional fixing components. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Combination Figures 1 to 4 The formaldehyde removal device shown includes a top shell 1, an air intake module 2 in the middle of the top shell 1, a drainage structure 3 on the outside of the air intake module 2, and a columnar double-layer cavity 4 at the bottom of the air intake module 2. The top and bottom of the double-layer cavity 4 are designed with pipe connections.

[0028] The air intake module 2 includes an air intake nozzle 21 and a connecting pipe 22 fixedly connected to its bottom. Several round holes are provided through the outer surface of the air intake nozzle 21.

[0029] The top shell 1 of the formaldehyde removal device is connected to the air intake module 2 by screws and clips.

[0030] The double-layer cavity 4 includes a cylindrical cavity 41 and an annular circular plate 42 arranged horizontally inside it. A mesh cylinder 43 is vertically arranged at the inner diameter of the annular circular plate 42, and a formaldehyde sensor 44 is installed on the annular circular plate 42.

[0031] The annular circular plate 42 divides the cylindrical cavity 41 into an upper detection cavity and a lower installation cavity. The cylindrical cavity 41 is a two-part assembly structure that is sealed together. The annular circular plate 42 is fixedly connected to the bottom of the upper cylindrical cavity 41 assembly. The annular circular plate 42 and the mesh cylinder 43 are integrally injection molded, and the mesh cylinder 43 has several air holes through it. The top of the mesh cylinder 43 is fixedly connected to the top wall of the cylindrical cavity 41.

[0032] The formaldehyde sensor 44 is electrically connected to the main control module.

[0033] The drainage structure 3 includes a groove 31 through which the connecting pipe 22 passes in the middle, and a drainage pipe fitting 32 is installed at the bottom of the groove 31.

[0034] The recess 31 should be recessed to a height no greater than twice the height of the air intake nozzle 21.

[0035] A connecting piece is fixedly provided on the inner bottom of the top shell 1 of the formaldehyde removal instrument for connecting with the cylinder shell of the formaldehyde removal instrument.

[0036] The inner side of the cylindrical cavity 41 at the bottom of the annular plate 42 is used to install the air intake blade.

[0037] The intake blades and motor are mounted on the inner side of the cylindrical cavity 41 via a bracket and are electrically connected to the main control module.

[0038] Working principle: During use, external air is drawn in through the round hole of the air intake nozzle 21 and enters the double-layer cavity 4 through the connecting pipe 22. Some of the gas passes through the air holes of the mesh cylinder 43 and enters the upper detection cavity, forming turbulence and fully contacting the surface of the formaldehyde sensor 44 to improve the detection sensitivity. The remaining gas is driven by the paddle to the subsequent purification module.

[0039] After the humid gas adsorbed and gathered near the air intake nozzle 21 turns into condensate, it sinks into the groove 31 of the drainage structure 3 due to gravity. The limiting design height of the groove 31 is ≤2 times the height of the nozzle to ensure that the liquid will not enter the air intake nozzle 21. The collected condensate is discharged through the drainage pipe 32 and the pipe to prevent the liquid from entering the detection chamber.

[0040] The formaldehyde sensor 44 collects the concentration data of formaldehyde in the air entering the detection chamber in real time and transmits it to the main control module through an electrical signal. The main control module dynamically adjusts the speed of the air intake blades and the purification intensity to achieve closed-loop control.
