Description

An intelligent bathtub and method capable of detecting odor

technical field

The invention relates to the technical field of bathroom products, in particular to an intelligent bathtub capable of detecting odors and a method thereof.

Background technique

According to medical research, there are various glands distributed in our body, and these glands are mainly distributed in the armpits, navel and anus. If the outside temperature changes, or the endocrine disorder is caused by mental stress, the secretion of our glands will increase, and our body will emit some smell. In real life, when people do not pay attention to personal hygiene, bacteria will grow in their bodies after a long time, which will produce peculiar smell.

Modern medicine has confirmed that when a person suffers from a certain disease, the body emits a special smell, and different diseases produce different smells. For example: 1) The smell of rotten apples is common in diabetic patients. When a diabetic patient's condition worsens, due to the production of a large number of ketone bodies, it will emit a rotten apple-like smell. 2) Ammonia smell, often seen in patients with nephritis. When renal failure occurs, due to the abnormal metabolism, the content of creatinine and urea nitrogen in the body increases, and there is a special ammonia smell in the mouth. 3) sour taste, common in rheumatism. 4) The smell of blood - it can be seen in patients with bleeding gums, upper gastrointestinal bleeding and bronchiectasis. When people take a bath in the bathtub, these smells can be emitted more easily.

Therefore, be badly in need of a kind of bathtub that can detect the relevant smell that human body sends out when people bathe, and it is analyzed and processed.

detailed description

The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

As shown in Figures 1 and 2, the present invention provides a smart bathtub that can detect odors, including a cylinder body 1 and a plurality of odor sensors 2 arranged on the cylinder body. The embedded system module 4 is also connected with the wireless transmission module 5 and the storage module 6 . Among them, the odor sensor 2 is used to detect the odor emitted by the human body when bathing; the signal processing module 3 is used to realize analog-to-digital conversion; The disease information and preventive measures corresponding to the smell; the wireless transmission module 5 is used to realize the communication between the embedded system module and the mobile intelligent terminal. In this way, the odor sensor 2 is used to detect the gas generated by the user when taking a bath in the bathtub, and the detection result is handed over to the signal processing module 3 and the embedded system module 4 for analysis, and the analysis result is transmitted to the user's smart terminal in real time through the wireless transmission module 5, such as Mobile phones, tablets, and provide users with corresponding preventive measures.

Among them, the odor sensor 2 is preferably a microfluidic detector, and four are provided, including odor sensors for detecting ammonia, hydrogen sulfide, ethanol and odor, which are respectively used for detecting corresponding gases.

Preferably, the embedded system module 4 adopts the LPC2214 processor of the model NXP company, and the LPC2214 is based on a microcontroller supporting real-time simulation and tracking of a 16/32-bit ARM7TDMI-S CPU, and has a high-speed embedded 256K byte Flash memory. A 128-bit wide memory interface and a unique acceleration architecture enable 32-bit code to run at maximum clock rates. Applications with tight control over code size can use 16-bit Thumb mode to reduce code size by more than 30% with little loss in performance.

Preferably, the signal processing module 3 adopts a TI MSP430F169 processor. The processor has ultra-low power consumption, supports three low-power consumption modes, and has powerful processing capabilities. The MSP430 series single-chip microcomputer is a 16-bit single-chip microcomputer with a reduced instruction set (RISC) structure, and one clock cycle can execute one instruction at 8MHz. When working under the crystal oscillator, the command speed can reach 8MIPS, and it also has high-performance analog technology and rich on-chip peripheral modules. In addition, it has a convenient and efficient development environment. At present, the MSP430 series has three types of devices: OTP type, FLASH type and ROM type. The FLASH type is widely used in China.

Preferably, the microfluidic detector is a semiconductor element, and the change of gas concentration is reflected by the change of its resistance value. The models TGS824, MQ825, TGS822, and TGS2600 are used to detect ammonia, hydrogen sulfide, ethanol, and odor respectively. The corresponding detection symptoms are the tendency of the user to have renal failure, gingivitis, alcoholism, and liver failure. When this type of sensor is working, it is only sensitive to the smell it detects, and it is not sensitive to other smells or gases. Therefore, after heating to a certain temperature, when the gas to be measured is in contact with the sensitive parts, a part of the molecules of the gas to be measured evaporate and adsorb In sensitive parts, it has the advantages of simple manufacture, fast response and high sensitivity.

The smell emitted by the user when taking a bath in the bathtub is collected by the microfluidic sensor. When the metal oxide crystal such as SnO ₂ in the sensor is heated to a certain high temperature in the air, the electrons on the surface of the crystal are transferred to a negative electrode adsorbed on the surface of the crystal. The charge on the oxygen of the crystal results in a positive charge left in a space charge layer. In this way, the surface potential energy forms a potential barrier, which impedes the flow of electrons. When ammonia gas appears, the surface concentration of negatively charged oxygen decreases, resulting in a decrease in the potential barrier of the grain boundary, and the reduced potential barrier reduces the resistance of the sensor, and the sensor resistance changes in a certain range of gas concentration The relationship equation between and the change of reducing gas concentration can be expressed as:

Rs＝-A[C] ^-α

Among them, Rs is the sensor resistance, A is a constant, [C] is the gas concentration, and α is the slope of the Rs curve.

The present invention also discloses a detection method based on the above-mentioned smart bathtub capable of detecting odors, which includes the following steps:

Step 1, each odor sensor 2 collects corresponding odor information, transmits the odor information to the embedded system module 4, and stores it in the storage module 6;

Step 2, the embedded system module 4 judges whether the number of acquisitions of the odor information corresponding to each odor sensor 2 reaches the threshold value of the number of times, and the threshold value of the number of times is set to seven times, if so, go to step 3; otherwise, the corresponding odor sensor 2 continues To collect odor information;

Step 3, the embedded system module 4 judges whether the multiple odor information collected continuously is in a state of continuous increase, and each increase is greater than the amplitude threshold, and the amplitude threshold is set to 0.05mV. If so, read the corresponding odor information from the storage module 6. The disease information and prevention information are sent to the smart mobile terminal by the wireless transmission module 5; otherwise, the corresponding odor sensor 2 continues to collect odor information.

The invention detects various odors emitted by the human body during bathing by adding an odor sensor to the existing bathtub, and predicts related diseases according to the detection results, thereby improving the intelligence of the bathtub, and the present invention The invention is simple in structure, convenient in operation, has a lot of market adaptability, and is convenient for popularization and application.
