Abstract
Description
Technical Field
[0001] The present application relates to the technical field of smart mattresses, and in particular to a dynamic negative ion-releasing bionic ecological mattress system. Background Art
[0002] With the rapid development of intelligent technology, its application areas are becoming increasingly extensive. In the home furnishing field, the use of intelligent technology on mattresses has become a trend. For example, pressure sensors are integrated into mattresses to monitor the user's posture and actively adjust the mattress's rebound strength. At the same time, because negative ions have beneficial functions such as improving sleep, anti-oxidation, and scavenging free radicals in the body, negative ion-related functional components are also integrated into mattresses. In the existing technology, the implementation of negative ion-releasing mattresses mainly adopts two methods: mineral powder mixing technology and electrode plate corona discharge technology. Among them, the mineral powder mixing technology is to grind minerals such as tourmaline and mix them into the fiber layer of a traditional mattress. The piezoelectric effect of the mineral spontaneously generates negative ions. This method has a low negative ion concentration. The electrode plate corona discharge technology actively ionizes the air through a high-voltage generator and an electrode plate system. Refer to patent CN212280716U. It can produce high-concentration small-particle negative ions (0.001–0.003μm) that can penetrate clothing and be absorbed by the human body.
[0003] During the control process, existing negative ion-releasing mattresses mainly determine the corresponding release amount based on the user's usage status. For example, no release is performed when not in use, the negative ion release concentration is increased during the sleeping stage, and the release amount is adaptively reduced during the deep sleep stage, thereby meeting different usage needs.
[0004] During actual use, the amount of negative ions in the space is affected by many factors. Therefore, the existing method of determining the release amount based solely on the user status cannot make the amount of negative ions in the space meet the set standards, and thus cannot achieve the best effect. Therefore, how to intelligently control the release amount of negative ions is the fundamental problem to be solved by the present invention. Summary of the Invention

[0057] The present application discloses a dynamic negative ion releasing bionic ecological mattress system, referring to Figure 1, including electrode plates, monitoring units and control units, wherein the electrode plates are used to generate high-concentration small-particle negative ions, and the technology for releasing negative ions is existing technology, which is not described in detail in this embodiment. The monitoring unit includes an environmental parameter sensor group, a micro negative ion sensor and a pressure sensor group. The environmental parameter sensor group includes a temperature and humidity sensor and a Pm2.5 sensor. Among them, two groups of temperature sensors are set, one group is used to monitor the ambient temperature of the space, and the other group is used to monitor the temperature of the electrode plate area.

Through the above process, on the basis of adjusting the negative ion release concentration according to the user's sleeping state, the negative ion release concentration is adjusted by the real-time monitored environmental parameters and negative ion concentration, which can ensure that the amount of released negative ions remains within the set numerical range after entering the space, thereby improving the effect of the negative ions. At the same time, when the negative ion concentration in the space environment itself is high, it can save energy consumption, thereby realizing intelligent control of the release amount of negative ions.
[0058] In one embodiment, a process for obtaining a negative ion baseline release concentration is provided, including: using formulas (2) to (3):

The acquisition process of formula (3) is set according to the relationship between negative ion concentration and humidity. In low humidity area (H<30%), due to insufficient ionization medium, hydrated ions form obstacles. In (30%≤H≤60%), water molecules reduce O2 ionization energy and increase collision ionization probability. In high humidity area (H≤>60%), cluster sedimentation is aggravated. Therefore, based on the above principles and test data, the reference function of negative ion concentration in humidity environment in formula (3) is obtained. Through the acquisition process of the above negative ion benchmark release concentration, the corresponding negative ion benchmark release concentration can be accurately determined according to the environmental state, so that the negative ion benchmark release concentration can correct the influence of the current temperature and humidity and Pm2.5 environment on the negative ion concentration, thereby ensuring that the number of negative ions in the final space is within the set range.

D Make adjustments to obtain the ideal negative ion concentration N after adjustment D1 , the ideal negative ion concentration N after adjustment D1 Substitute into formulas (1) to (3) to obtain the new negative ion baseline release concentration as the adjusted negative ion release concentration. Therefore, the adjusted negative ion release concentration can be dynamically adjusted according to the different sleep states of the user. Then, according to the real-time monitored negative ion concentration and the adjusted negative ion ideal concentration N D1 A comparative analysis is performed and the negative ion compensation concentration is determined based on the comparative analysis. Therefore, the negative ion compensation concentration can be dynamically adjusted according to the difference between the real-time monitoring result and the predicted result. The negative ion dynamic release concentration is determined based on the adjusted negative ion release concentration and the negative ion compensation concentration, thereby ensuring that the amount of released negative ions remains within the set numerical range after entering the space, thereby improving the effect of negative ions, saving energy consumption, and realizing intelligent control of the release amount of negative ions.

At the same time, the distribution of pressure positions is compared with preset distribution states of different postures to thereby identify the user's body posture, and judge the user's sleep state based on the number of changes in the user's body posture per unit time and the user's breathing rhythm, thereby enabling the judgment of the user's sleep state. It should be noted that the micro-motion detection process and the technology of judging the user's posture based on pressure are existing technologies in the field of smart mattresses and will not be further described here.

It is set according to the numerical range calculated based on the number of turns and the breathing state factor and the degree of influence in the empirical data. Therefore, the obtained user sleep state evaluation value λ can reflect the user's current sleep state. Then, the adjusted ideal negative ion concentration N is obtained based on the user's sleep state. D1 , and then dynamically adjust the amount of negative ions released according to the user's different sleep states.

By obtaining the negative ion compensation concentration ΔNi under the combined influence of the difference mean and the fluctuation influence, the dynamic release concentration of negative ions can be obtained more accurately, ensuring that the amount of released negative ions remains within the set numerical range when entering the space, thereby improving the effect of negative ions.
[0072] Therefore, through N set (t) = N st (t)+ΔNi(t) is used to calculate the dynamic release concentration of negative ions N set (t); where N st(t) is the adjusted negative ion release concentration calculated at the current time point. By controlling the electrode plate according to the dynamic release concentration of negative ions, it can ensure that the amount of released negative ions remains within the set numerical range after entering the space, thereby improving the effect of the negative ions. At the same time, when the negative ion concentration in the space environment is high, it can save energy consumption, thereby realizing intelligent control of the release amount of negative ions.
