In view of this, a first aspect embodiment of the present invention provides a purification apparatus, including: the main body part is provided with a purifying cavity for containing purifying materials; at least a portion of the heating assembly extends into the decontamination chamber to heat the decontamination material.

The purification device proposed by the present embodiment includes a main body portion and a heating assembly. Wherein, the inside of main part has the purification chamber, purifies the intracavity and fills purifier, alleviates indoor carbon dioxide concentration through purifier absorption carbon dioxide. And adopt heating element to heat purifying material for purifying material can release carbon dioxide when not possessing the ability of continuing to adsorb carbon dioxide, specifically to the outdoor carbon dioxide who releases of discharging, thereby makes purifying material have the ability of adsorbing carbon dioxide again, realizes the reuse to purifying material, prolongs purifier's live time.

In addition, the purifying material in the purifying cavity is heated by extending a part or the whole of the heating component into the purifying cavity. Compared with the prior art in which the heating device is arranged on one side of the solid amine to heat the solid amine and the purification material is required to be subjected to heat transfer to integrally heat the purification material, the heating assembly extends into the purification material, so that the heating assembly can directly heat the purification material at the periphery, and the purpose of heating the whole purification material from the inside of the purification cavity is achieved. On the one hand, the purification material is beneficial to being heated uniformly, so that the purification material is beneficial to releasing carbon dioxide uniformly, that is, the carbon dioxide is desorbed, and the phenomenon that the purification material is partially not fully released carbon dioxide due to low temperature to influence the reutilization of the purification material is avoided. On the other hand, the phenomenon that the heating assembly heats one side of the solid amine in a concentrated mode, and the part, close to the heating assembly, of the solid amine is damaged due to overhigh temperature, so that the performance of adsorption and desorption of carbon dioxide of the solid amine is reduced, and the service life of the solid amine is influenced. Moreover, because heating element directly stretches into and purifies intracavity portion, the purifying material on every side is heated from inside, still is favorable to realizing the quick desorption of carbon dioxide to purifier's purification efficiency improves. On the other hand, the heating component partially or completely extends into the purifying cavity, namely the heating component and the purifying cavity are combined into a whole, so that the volume of the purifying device is reduced, and the purifying device with small volume is conveniently applied to household appliances such as air conditioners, air purifiers and the like.

In one possible design, the heating assembly includes: the first heating parts are distributed in the purification cavity at intervals along the first direction.

In this design, the heating assembly includes a plurality of first heating portions, and the plurality of first heating portions are distributed at intervals in the purifying chamber, that is, the plurality of first heating portions extend into the purifying chamber in a distributed manner and are inserted into the purifying material. The purification material is beneficial to being uniformly heated, so that carbon dioxide is uniformly released at each position of the purification material, and the desorption efficiency of the purification material is improved. So that the purifying material can recover the function of adsorbing carbon dioxide more quickly, and further improve the purifying efficiency of the purifying device.

In one possible design, the heating assembly further comprises: and the two adjacent first heating parts are connected through one second heating part.

In this design, still include the second heating portion through making heating element to make every second heating portion connect two adjacent first heating portions, heat purifying material jointly through first heating portion and second heating portion, increased heating element's heating area, be favorable to improving purifying material's desorption efficiency, thereby improve purifier's purification efficiency.

Moreover, the second heating parts are connected with the adjacent first heating parts, so that the first heating parts can be connected in series through the second heating parts, if the first heating parts are electrically connected with the adjacent second heating parts, the heating assembly is favorably provided with two outgoing lines, a complex power supply line is not required to be provided for the first heating parts, and the structure of the purification device is simplified.

Further, the at least one second heating part and the plurality of first heating parts are integrally formed. The assembly steps of the heating assembly are simplified, and the purification device is favorable for quick forming. For example, all the first heating portions and all the second heating portions belong to a whole electrothermal film, or all the first heating portions and all the second heating portions belong to a continuously distributed liquid supply pipe.

In one possible design, the first heating portion includes a first electrothermal film.

In this design, through adopting the electric heat membrane to heat purifying material, because first electric heat membrane generates heat evenly, can be favorable to purifying material evenly to release carbon dioxide to purifying material evenly heating. On one hand, the purification material is prevented from partially releasing carbon dioxide insufficiently due to low temperature, and the reutilization of the purification material is prevented from being influenced. On the other hand, the damage of the purification material due to overhigh local temperature is avoided, and the performance attenuation of the purification material for adsorbing and desorbing carbon dioxide is influenced, so that the service life of the solid amine is influenced.

Specifically, by making the heating assembly include a plurality of first electric heating films, each of the first electric heating films is configured as one first heating portion. Also, a plurality of first electric heat membrane along first direction interval distribution in purifying the intracavity, can realize the layering heating to whole purifying material, be favorable to purifying material thermally equivalent.

In one possible design, the first heating part includes a first supply pipe that heats the purification material by the temperature of the liquid inside.

In this design, the purifier material is heated by exchanging heat with the liquid in the first liquid supply tube. Since the temperature of the liquid, for example the boiling point of water, has a certain limit, for example 100 ℃, the maximum temperature of the liquid can be controlled by controlling the kind of the liquid. Tests show that when the purification material is solid amine, the desorption speed of carbon dioxide is low and the carbon dioxide cannot be completely desorbed when the temperature of the purification material is lower than 80 ℃; the re-adsorption period is long, and the performance of the purification material cannot be fully exerted. When the temperature of the purifying material is between 80 ℃ and 100 ℃, the desorption speed of the carbon dioxide is high, and the carbon dioxide can be completely desorbed. When the solid amine temperature is higher than 100 ℃, the purification material has the problem of oxidative decomposition. Since there is little possibility of arranging thermocouples throughout the purification material to detect the temperature at all locations, when there is local overheating (temperature exceeding 100 ℃), it is not effective to ensure safe and normal operation of the purification material. Furthermore, the purifying material is heated by adopting the temperature of the liquid, for example, the purifying material is heated by adopting hot water, the boiling point of the water is 100 ℃, and the temperature of the hot water is generally not higher than 100 ℃, so that the material failure caused by local overheating of the purifying material can be effectively prevented, and the failure of the purifying device is avoided. Moreover, the number of the temperature measuring devices is favorably reduced, only one temperature measuring device can be arranged in the first liquid supply pipe to detect the water temperature, and the temperature can be ensured not to exceed 100 ℃ all the time without temperature monitoring in the purifying material.

In a particular application, the first supply tube may be in direct communication with a heat source, such as a tap or the like that provides heated water. Of course, the first liquid supply pipe may be communicated with the liquid supply channel, and the liquid in the liquid supply channel is heated by the heating element, so that the temperature of the liquid in the first liquid supply pipe can effectively heat the purifying material.

Further, in a case where the heating assembly further includes a second heating part, the second heating part includes a second supply pipe that heats the purification material by a temperature of the liquid inside. And two adjacent first liquid supply pipes are communicated through a second liquid supply pipe.

Specifically, after all the first liquid supply pipes and all the second liquid supply pipes are communicated with each other, a liquid supply inlet and a liquid supply outlet are formed, so that the liquid supply inlet is communicated with the liquid outlet of the liquid supply channel, and the liquid supply outlet is communicated with the liquid inlet of the liquid supply channel. The liquid circulation flow can be realized, the purification material can be fully heated, the heating efficiency is improved, and the heating time is shortened.

In one possible design, the liquid supply passage includes a reservoir, and the heating element is for heating liquid in the reservoir; all the first liquid supply pipes and all the second liquid supply pipes are communicated with each other to form a liquid supply inlet and a liquid supply outlet; the liquid outlet of the liquid storage tank is communicated with the liquid supply inlet, and the liquid inlet of the liquid storage tank is communicated with the liquid supply outlet.

And under the desorption state, can close first valve body, close the second valve body, make the fan stop operation. At the moment, the heating assembly and the purifying material are communicated with the outside only through the second air outlet channel in a sealed space. Open heating element and the pump body, cooperate through heating element and pump body, constantly arrange the carbon dioxide that comes out the desorption to outdoor through second air-out passageway.

In one possible design, the purification device further comprises: the first temperature measuring device is arranged on one side of the purification cavity close to the air inlet channel, and/or the second temperature measuring device is arranged on one side of the purification cavity close to the first air outlet channel.

In this design, set up first temperature measuring device through the one side that is close to inlet air channel at the purification chamber, and/or set up second temperature measuring device in the one side that is close to first air-out passageway at the purification chamber, be favorable to according to purifying the temperature of material in the chamber, control heating element's running state avoids purifying the material high temperature and impaired to and avoid purifying the material temperature and cross lowly and unable abundant desorption carbon dioxide.

In one possible design, the purification material comprises a solid amine and the purification device is a carbon dioxide purification device.

An embodiment of the second aspect of the present invention provides a control method for a purification apparatus according to any one of the above technical solutions, including: responding to the desorption instruction, and controlling a heating assembly of the purification device to operate; and controlling the first valve body of the purification device and the second valve body of the purification device to be closed, stopping the fan of the purification device and operating the pump body of the purification device so as to enable the purification device to enter a desorption state.

The present embodiment proposes a control method of a purification apparatus. Specifically, when receiving the desorption instruction, respond to this desorption instruction, like control purifier's heating element operation, control purifier's first valve body is closed, control purifier's second valve body is closed, control purifier's fan stop operation and control purifier's pump body operation, at this moment, purifier gets into desorption state. Specifically, when the purification device enters the desorption state, the heating assembly and the purification material are both in a closed space, and only exhaust is carried out through the pump body. At this moment, through making heating element and pump body cooperate, the carbon dioxide that comes out the desorption constantly arranges to outdoor through the pump body, is favorable to the quick desorption of purifier to improve purifier's purification efficiency. Moreover, the adsorption and desorption processes can be repeatedly and circularly carried out, carbon dioxide gas generated by human activities can be effectively removed, and the indoor concentration is always maintained in a range that the human body feels comfortable.

In one possible design, the desorption instruction is generated based on a comparison result between a change in the carbon dioxide concentration detected by the carbon dioxide detection device of the purification device and a set value.

In this design, when the change in the carbon dioxide concentration detected by the carbon dioxide detection device is less than or equal to the set value, that is, when the carbon dioxide concentration detected by the carbon dioxide detection device is no longer decreasing, it indicates that the purification material has failed to continue adsorbing carbon dioxide, and a desorption instruction may be generated to stop the useless adsorption function and perform desorption. When the change of the carbon dioxide concentration detected by the carbon dioxide detection device is higher than a set value, the purification material can still adsorb carbon dioxide and can continue to adsorb the carbon dioxide.

Specifically, the carbon dioxide detection device detects the concentration of carbon dioxide at set intervals, and the change value of the concentration of carbon dioxide detected by the carbon dioxide detection device is the difference between the former detection value and the latter detection value.

In one possible design, the control method further includes: controlling the heating assembly to stop heating based on the condition that the temperature value detected by the first temperature measuring device of the purifying device and/or the second temperature measuring device of the purifying device is greater than or equal to the first set temperature value; controlling the heating assembly to continue heating based on the condition that the temperature value detected by the first temperature measuring device of the purifying device and/or the second temperature measuring device of the purifying device is less than or equal to a second set temperature value; wherein, the first set temperature value is greater than the second set temperature value.

In the design, when the temperature value detected by any one of the first detection device and the second detection device is greater than or equal to the first set temperature value, the temperature of the purification material is very high, and the purification material is easily damaged. And when any temperature value that detects was less than the second when setting for the temperature value in first detection device and the second detection device, it is lower to explain purifying material's temperature this moment, and unable abundant desorption carbon dioxide heats through control heating element, is favorable to purifying material to realize quick desorption. Moreover, the temperature of the purifying material is kept between the first set temperature value and the second set temperature value, so that the purifying material can maintain a long-time better desorption state, and the rapid desorption of the purifying material is facilitated.

In one possible design, the control method further includes: controlling the heating assembly to stop running in response to the adsorption instruction; and controlling the first valve body and the second valve body to be opened, the fan to be operated and the pump body to be stopped so as to enable the purification device to enter an adsorption state.

In this design, when receiving the adsorption instruction, respond to this adsorption instruction, for example control heating element stop operation, control first valve body and second valve body and open, control fan operation and pump body stop operation to get into the suction state. Specifically, in the adsorption state, the fan can suck the gas containing high-concentration carbon dioxide in the room into the purification cavity, and the gas is adsorbed by the purification material in the purification cavity and then discharged back to the room. Because the purification material can quickly adsorb carbon dioxide, the concentration of the carbon dioxide in the room can be continuously reduced.

A third aspect of the present invention provides a control device for a purification device, including: a memory having a computer program stored thereon; a controller that executes a computer program to implement the steps of the control method of the purification apparatus according to any one of the above-described embodiments.

The present embodiment proposes a control device of a purification device, which includes a memory and a controller, wherein the controller executes a computer program to implement the steps of the control method of the purification device according to any one of the second aspect. Therefore, the control device of the purification device has all the beneficial technical effects of any one of the above control methods of the purification device, and the detailed description is omitted here.

Detailed Description

So that the manner in which the above recited aspects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A purification apparatus according to some embodiments of the present invention is described below with reference to fig. 1 to 8.

The first embodiment is as follows:

as shown in fig. 2, a purification apparatus includes a main body 110 and a heating assembly. The main body 110 has a purification chamber 120 therein, and the purification chamber 120 is filled with a purification material, and the purification material adsorbs carbon dioxide to reduce the concentration of carbon dioxide in the room. And adopt heating element to heat purifying material for purifying material can release carbon dioxide when not possessing the ability of continuing to adsorb carbon dioxide, specifically to the outdoor carbon dioxide who releases of discharging, thereby makes purifying material have the ability of adsorbing carbon dioxide again, realizes the reuse to purifying material, prolongs purifier's live time.

The related art purification apparatus is shown in fig. 1, and includes a purification chamber 120 ', a heating assembly 130 ' disposed at one side of the purification chamber 120 '; the air purifier also comprises an air inlet channel 160 ', a first air outlet channel 170 ' and a second air outlet channel 210 ' which are communicated with the purifying cavity; and a fan 190 'disposed in the first air outlet channel 170', a first temperature measuring device 240 'disposed at a side of the purifying chamber 120' close to the air inlet channel 160 ', a second temperature measuring device 250' disposed at a side of the purifying chamber 120 'close to the first air outlet channel 170', and a pump body 220 'disposed on the second air outlet channel 210'.

Fig. 6 shows temperature values detected by the first temperature measuring device 240 ' and the second temperature measuring device 250 ' under different heating powers (200W to 500W) of the heating assembly 130 ' in the related art. Due to the small flow rate (10L/min to 100L/min) of the pump 220 ', the suction force is weak, and the heat convection and conduction capability generated by the heating assembly 130' is weak, so that the temperature difference between the end of the purifying material close to the air inlet channel 160 'and the end close to the first air outlet channel 170' is very large (up to 50 ℃), which may cause the purifying material close to the air inlet channel 160 'to be oxidized, decomposed and failed due to over-high temperature, while the purifying material close to the first air outlet channel 170' may not be effectively and completely desorbed due to insufficient temperature. In this case, the lifetime and performance of the purification material are greatly affected.

The present embodiment heats the decontamination material within the decontamination chamber 120 by extending a portion or all of the heating element 130 into the decontamination chamber 120. Compared with the prior art in which the heating device is arranged on one side of the solid amine to heat the solid amine and the purification material needs to be heated up integrally by heat transfer, the heating assembly 130 extends into the purification material, so that the heating assembly 130 can directly heat the purification material around, and the whole purification material is heated from the inside of the purification chamber 120. On the one hand, the purification material is beneficial to being heated uniformly, so that the purification material is beneficial to releasing carbon dioxide uniformly, that is, the carbon dioxide is desorbed, and the phenomenon that the purification material is partially not fully released carbon dioxide due to low temperature to influence the reutilization of the purification material is avoided. On the other hand, the phenomenon that the heating assembly 130 heats one side of the solid amine in a concentrated manner, and the part of the solid amine close to the heating assembly 130 is damaged due to overhigh temperature, so that the performance of adsorbing and desorbing carbon dioxide of the solid amine is reduced, and the service life of the solid amine is influenced can be effectively avoided. As shown in FIG. 7, the difference between the temperature values detected by the first temperature measuring device 240 and the second temperature measuring device 250 is significantly reduced (less than 10 ℃) at different heating powers (200W to 500W). Moreover, because the heating assembly 130 directly extends into the interior of the purifying cavity 120, the surrounding purifying materials are heated from the interior, and the rapid desorption of carbon dioxide is facilitated, so that the purifying efficiency of the purifying device is improved. On the other hand, since the heating assembly 130 partially or completely extends into the purifying chamber 120, that is, the heating assembly 130 and the purifying chamber 120 are integrated, the volume of the purifying apparatus can be reduced, so that the purifying apparatus with small volume can be conveniently applied to household electrical appliances such as air conditioners, air purifiers, and the like.

In a particular application, the purification material comprises a solid amine and the purification device is a carbon dioxide purification device.

Further, the heating assembly 130 includes a plurality of first heating portions, and the plurality of first heating portions are distributed at intervals in the purifying chamber 120, that is, the plurality of first heating portions extend into the purifying chamber 120 in a distributed manner and are inserted into the purifying material. The purification material is beneficial to being uniformly heated, so that carbon dioxide is uniformly released at each position of the purification material, and the desorption efficiency of the purification material is improved. So that the purifying material can recover the function of adsorbing carbon dioxide more quickly, and further improve the purifying efficiency of the purifying device.

In a specific application, the plurality of first heating parts are distributed at intervals in a plumb direction or a horizontal direction.

Specifically, in the case where each of the first heating sections extends entirely in the plumb direction, the plurality of first heating sections are distributed at intervals in the horizontal direction. In the case where the entire first heating sections extend in the horizontal direction, the plurality of first heating sections are arranged at intervals in the plumb direction. Which is beneficial to heating the purifying material more uniformly. Of course, each of the first heating portions may also extend obliquely with respect to the vertical line.

Further, the heating assembly 130 further includes second heating parts, and each second heating part connects two adjacent first heating parts. Through first heating portion and second heating portion heat the purifying material jointly, increased heating element 130's heating area, be favorable to improving purifying material's desorption efficiency to improve purifier's purification efficiency.

Moreover, because the second heating parts are connected with the adjacent first heating parts, the plurality of first heating parts can be connected in series through the second heating parts, and if the first heating parts are electrically connected with the adjacent second heating parts, the heating assembly 130 can be integrally provided with two outgoing lines, a complex power supply line is not required to be provided for the plurality of first heating parts, and the structure of the purification device is simplified.

Further, the at least one second heating part and the plurality of first heating parts are integrally formed. The assembly steps of the heating assembly 130 are simplified, which facilitates the rapid molding of the purification apparatus. For example, all the first heating portions and all the second heating portions belong to a whole electrothermal film, or all the first heating portions and all the second heating portions belong to a continuously distributed liquid supply pipe.

Example two:

on the basis of the first embodiment, as shown in fig. 3, in order to effectively solve the problem of uniformity of heating of the purification material, heating of the purification material by the electrothermal film is further limited. Because the first electric heating film 131 generates heat uniformly, the purifying material can be heated uniformly, and carbon dioxide can be released uniformly by the purifying material. On one hand, the purification material is prevented from partially releasing carbon dioxide insufficiently due to low temperature, and the reutilization of the purification material is prevented from being influenced. On the other hand, the damage of the purification material due to overhigh local temperature is avoided, and the performance attenuation of the purification material for adsorbing and desorbing carbon dioxide is influenced, so that the service life of the solid amine is influenced.

In a specific embodiment, as shown in fig. 3, the heating assembly 130 includes a plurality of first heating parts 131, and each of the first heating parts 131 is configured as one first heating part. Also, the first electric heating films 131 are distributed in the purifying cavity 120 at intervals along the first direction, so that layered heating of all the purifying materials can be realized, and uniform heating of the purifying materials is facilitated.

In another specific embodiment, as shown in fig. 3, the second heating portion is made to include a second electrothermal film 132. And the first electric heating film 131 and the second electric heating film 132 are integrally formed and electrically connected. Make a plurality of first electric heat membrane 131 and at least one second electric heat membrane 132 constitute a bigger integral type electric heat membrane of whole area jointly in fact, be favorable to making heating element 130 whole have two lead-out wires can, need not to provide complicated power supply line for a plurality of first heating portions, simplify purifier's structure.

Example three:

unlike the second embodiment, as shown in fig. 4, the first heating part includes the first liquid supply pipe 135, and the first liquid supply pipe 135 heats the purification material by the temperature of the liquid inside.

In this embodiment, the purification material is heated by exchanging heat with the liquid in the first liquid supply tube 135. Since the temperature of the liquid, for example the boiling point of water, has a certain limit, for example 100 ℃, the maximum temperature of the liquid can be controlled by controlling the kind of the liquid. It is verified that, in the case that the purifying material is solid amine, as shown in fig. 5, when the temperature of the purifying material is lower than 80 ℃, the desorption speed of carbon dioxide is slow and the carbon dioxide cannot be completely desorbed; the re-adsorption period is long, and the performance of the purification material cannot be fully exerted. When the temperature of the purifying material is between 80 ℃ and 100 ℃, the desorption speed of the carbon dioxide is high, and the carbon dioxide can be completely desorbed. When the solid amine temperature is higher than 100 ℃, the purification material has the problem of oxidative decomposition. Since there is little possibility of arranging thermocouples throughout the purification material to detect the temperature at all locations, when there is local overheating (temperature exceeding 100 ℃), it is not effective to ensure safe and normal operation of the purification material. Furthermore, the purifying material is heated by adopting the temperature of the liquid, for example, the purifying material is heated by adopting hot water, the boiling point of the water is 100 ℃, and the temperature of the hot water is generally not higher than 100 ℃, so that the material failure caused by local overheating of the purifying material can be effectively prevented, and the failure of the purifying device is avoided. Moreover, the number of temperature measuring devices is advantageously reduced, and it is sufficient to arrange a temperature measuring device in the first liquid supply tube 135 to detect the water temperature, and it is possible to ensure that the temperature does not exceed 100 ℃ all the time without temperature monitoring in the purification material.

In particular applications, the first supply tube 135 may be in direct communication with a heat source, such as a faucet or the like that provides heated water. Of course, the first liquid supply tube 135 can also be connected to the liquid supply channel, and the liquid in the liquid supply channel can be heated by the heating element 134, so that the temperature of the liquid in the first liquid supply tube 135 can effectively heat the purification material.

Further, as shown in fig. 4, in the case that the heating assembly further includes a second heating part, the second heating part includes a second supply pipe 136, and the second supply pipe 136 heats the purification material by the temperature of the liquid inside. And makes two adjacent first liquid supply tubes 135 communicate with each other through one second liquid supply tube 136. Since the first supply pipe 135 and the second supply pipe 136 heat the purification material together, the heating effect and the heating uniformity are improved.

Specifically, as shown in fig. 4, a plurality of first liquid supply pipes 135 and at least one second liquid supply pipe 136 may be connected to form an integrated liquid supply line. That is, the integrated liquid supply line is bent several times to form a plurality of straight extension sections and at least one bent section, each straight extension section is configured as a first liquid supply pipe 135, and each bent section is configured as a second liquid supply pipe 136. The plurality of first supply tubes 135 and the at least one second supply tube 136 are conveniently formed and formed at a high speed. The integrated liquid supply line has a liquid supply inlet and a liquid supply outlet.

Further, the heating assembly further includes a liquid supply passage communicating with all of the first liquid supply tubes 135 and the second liquid supply tubes 136; a heating element 134, the heating element 134 for heating the liquid in the liquid supply passage.

In a specific application, the liquid in the liquid supply channel can be heated in real time, so that the liquid with higher temperature can enter the first liquid supply pipe 135 and the second liquid supply pipe 136 in real time to heat the purifying material; it is also possible to preheat the liquid in the liquid supply passage and then supply the liquid at a higher temperature into the first liquid supply pipe 135 and the second liquid supply pipe 136.

Specifically, as shown in fig. 4, all of the first liquid supply tubes 135 and all of the second liquid supply tubes 136 are connected to each other to form a liquid supply inlet and a liquid supply outlet, such that the liquid supply inlet is connected to the liquid outlet of the liquid supply channel, and the liquid supply outlet is connected to the liquid inlet of the liquid supply channel. Can realize that liquid circulation flows, be favorable to continuously providing liquid to the feed pipe, be favorable to the abundant heating purifying material, improve heating efficiency, it is long when shortening the heating.

In a specific embodiment, as shown in fig. 4, the liquid supply channel includes a liquid storage tank 133, and the heating element 134 heats the liquid in the liquid storage tank 133, and particularly, the heating element 134 may be disposed in the liquid storage tank 133 to ensure the heating effect. Moreover, a liquid supply inlet and a liquid supply outlet are formed after all the first liquid supply pipes 135 and all the second liquid supply pipes 136 are communicated with each other, so that the liquid outlet of the liquid storage box 133 is communicated with the liquid supply inlet, and the liquid inlet of the liquid storage box 133 is communicated with the liquid supply outlet, so that liquid circulation flow can be realized, the purification material can be fully heated, the heating efficiency is improved, and the heating duration is reduced.

In another embodiment, the liquid supply passage is a third liquid supply tube (not shown), and the heating element 134 heats the third liquid supply tube directly.

In a specific application, the heating assembly further comprises a pump means for pumping the liquid in the liquid supply channel to the first liquid supply tube 135 and/or the second liquid supply tube 136.

Example four:

unlike the second embodiment, as shown in fig. 4, the heating assembly 130 includes a liquid storage tank 133, a heating element 134, and a plurality of first liquid supply pipes 135. Wherein the heating element 134 is capable of heating the liquid in the reservoir 133; a first end of each first supply pipe 135 is communicated with the outlet of the tank 133, a second end of each first supply pipe 135 is communicated with the inlet of the tank 133, and each first heating part includes one first supply pipe 135.

In this embodiment, by heating the water in the storage tank 133 by using the heating element 134 and supplying the hot water to the first liquid supply pipe 135, the purifying material is heated by the first liquid supply pipe 135, and the boiling point of the water is 100 ℃, the hot water generally does not exceed the temperature of 100 ℃, so that the material failure caused by local overheating of the purifying material can be effectively prevented, and the failure of the purifying device can be avoided. Moreover, the number of the temperature measuring devices is favorably reduced, only one temperature measuring device can be arranged in the 135 pipelines of the first liquid supply pipe to detect the water temperature, and the temperature can be ensured not to exceed 100 ℃ all the time without monitoring the temperature in the purifying material.

Specifically, each heating part is made to include one first liquid supply pipe 135. The first end and the second end of each first liquid supply tube 135 are communicated with the liquid storage tank 133, so that the liquid storage tank 133 and the first liquid supply tubes 135 can form a circulation loop, which is beneficial to the liquid storage tank 133 to continuously provide liquid to the plurality of first liquid supply tubes 135.

In one embodiment, each of the first liquid supply tubes 135 is a flat tube, and has a larger contact area with the purification material, thereby facilitating uniform heating of the purification material.

In another specific application, the first supply tube 135 is a stainless steel tube.

Further, the heating element 134 is a heating wire or a PTC thermistor.

In a specific embodiment, as shown in fig. 3, the second supply pipe 136 is used to connect two adjacent first supply pipes 135, such that the second supply pipe 136 is communicated with the adjacent first supply pipes 135. The plurality of first supply pipes 135 and the at least one second supply pipe 136 may be connected to form an integrated supply line. That is, the integrated liquid supply line is bent several times to form a plurality of straight extension sections and at least one bent section, each straight extension section is configured as a first liquid supply pipe 135, and each bent section is configured as a second liquid supply pipe 136. The plurality of first supply tubes 135 and the at least one second supply tube 136 are conveniently formed and formed at a high speed.

Further, the heating assembly 130 further comprises a pump device (not shown) for pumping the liquid in the liquid storage tank 133 to the plurality of first liquid supply pipes 135.

Example five:

on the basis of any of the above embodiments, as shown in fig. 2 to 4, a plurality of first partition plates 140 are further defined and spaced in the purification chamber 120, and the plurality of first partition plates 140 partition the space in the purification chamber 120 to separate the purification materials. Compared with the condition that a large amount of purification materials are stacked in one cavity and the stacking density is high under the action of gravity, the purification materials are favorably and uniformly filled in the separated small cavities, so that the wind resistance is favorably reduced, and the purification efficiency of the purification device is improved.

In addition, by providing the plurality of first heating parts to the plurality of first partition plates 140, it is advantageous to ensure the mounting stability of the first heating parts.

Further, as shown in fig. 2 to 4, a plurality of first partition plates 140 are spaced apart in the plumb direction in the purge chamber 120. Since the purification material is uniformly spread on the plurality of first partition plates 140 by gravity and on the first heating part on the upper surfaces of the plurality of first partition plates 140, it is advantageous to uniformly heat the purification material.

In a specific application, in the case that the first heating part includes the first electrothermal films 131, each of the first electrothermal films 131 is disposed on one of the first partition plates 140, and since the first electrothermal films 131 have the characteristics of fast temperature rise and uniform heating, it is advantageous to uniformly heat the purification material.

Wherein, the first electric heating film 131 may be disposed on the upper surface of the first partition plate 140; or may be provided on both the upper surface of the first barrier 140 and the lower surface of the first barrier 140. For example, the first electric heating film 131 is alternately wound on the first barrier 140 in a horizontal direction.

In another specific application, in the case where the first heating part includes the first supply pipe 135, it is advantageous to ensure the installation stability of the plurality of first supply pipes 135 by disposing the plurality of first supply pipes 135 on the plurality of first partitions 140.

In a specific embodiment, as shown in fig. 3 and 4, the purification apparatus further includes a plurality of second partitions 150, the plurality of second partitions 150 are spaced apart in the purification chamber 120 along the second direction, and the plurality of first partitions 140 and the plurality of second partitions 150 are distributed across and partition the purification chamber 120 into a plurality of sub-chambers.

In this embodiment, the plurality of second partition plates 150 are distributed at intervals in the purification chamber 120, and the plurality of second partition plates 150 and the plurality of first partition plates 140 are distributed in a crossed manner, that is, the space in the purification chamber 120 is divided into smaller small cavities by the plurality of first partition plates 140 and the plurality of second partition plates 150, so that the purification material is more uniformly filled in the divided small cavities, thereby being beneficial to reducing wind resistance and improving purification efficiency of the purification apparatus.

In a specific application, the plurality of second partitions 150 are spaced apart in the horizontal direction. At this time, the air intake direction of the purification apparatus is a direction perpendicular to the paper surface inward as in fig. 3 and 4.

Example six:

on the basis of any of the above embodiments, as shown in fig. 2, the purifying device further includes an air inlet channel 160, a first air outlet channel 170, and a second air outlet channel 210, which are communicated with the purifying cavity 120. In the adsorption state, the heating assembly 130 may be in a heating stop state, the pump body 220 may be in a running stop state, the first valve body is opened to open the air inlet channel 160, the second valve body 180 is opened to open the first air outlet channel 170, and the blower 190 is started. So that the fan 190 can suck the indoor gas containing high-concentration carbon dioxide into the purifying chamber 120, and the gas is exhausted back to the indoor through the first air outlet channel 170 after being adsorbed by the purifying material in the purifying chamber 120. Because the purification material can quickly adsorb carbon dioxide, the concentration of the carbon dioxide in the room can be continuously reduced.

In the desorption state, the first valve body can be closed, and the second valve body 180 can be closed, so that the fan 190 stops operating. At this time, the heating assembly 130 and the purifying material are in a sealed space and are communicated with the outside only through the second outlet air channel 210. Open heating element 130 and pump body 220, cooperate through heating element 130 and pump body 220, constantly discharge the carbon dioxide that comes out the desorption to outdoor through second air-out passageway 210.

In a particular application, the pump body 220 is a vacuum pump.

In a specific embodiment, as shown in fig. 2, the purification device further includes a carbon dioxide detecting device 230 disposed in the first air outlet channel 170 and/or the air inlet channel 160.

In this embodiment, by providing the carbon dioxide detection device 230 in the first air outlet channel 170 and/or the air inlet channel 160, the concentration of carbon dioxide is detected by the carbon dioxide detection device 230, which is beneficial to determining whether the purification material can further adsorb carbon dioxide according to the detection result, and is beneficial to controlling the purification device to enter the desorption state when the concentration of carbon dioxide is detected not to be reduced any more.

In another specific embodiment, as shown in fig. 2, by disposing the first temperature measuring device 240 on a side of the purifying chamber 120 close to the air inlet channel 160 and/or disposing the second temperature measuring device 250 on a side of the purifying chamber 120 close to the first air outlet channel 170, it is beneficial to control an operation state of the heating assembly 130 according to a temperature of the purifying material in the purifying chamber 120, so as to prevent the purifying material from being damaged due to an excessively high temperature, and prevent the purifying material from being damaged due to an excessively low temperature and being unable to sufficiently desorb carbon dioxide.

In a specific application, the first temperature measuring device 240 and the second temperature measuring device 250 are disposed on opposite sides of the purification chamber 120.

Example seven:

as shown in fig. 8, a control method of a purification apparatus includes:

step 302, responding to the desorption instruction, and controlling the heating component 130 of the purification device to operate; and controlling the first valve body 180 of the purification device and the second valve body 180 of the purification device to be closed, stopping the fan 190 of the purification device and operating the pump body 220 of the purification device so as to enable the purification device to enter a desorption state.

The present embodiment proposes a control method of a purification apparatus. Specifically, when receiving the desorption instruction, the desorption instruction is responded, such as the operation of the heating assembly 130 of the purification device, the closing of the first valve body of the purification device, the closing of the second valve body 180 of the purification device, the stop of the fan 190 of the purification device, and the operation of the pump body 220 of the purification device, at this time, the purification device enters the desorption state. Specifically, when the purification apparatus enters the desorption state, the heating assembly 130 and the purification material are both in a closed space, and only the pump body 220 exhausts the gas to the outside. At this moment, through making heating element 130 and pump body 220 cooperate, the carbon dioxide that comes out the desorption constantly arranges to outdoor through pump body 220, is favorable to the quick desorption of purifier to improve purifier's purification efficiency. Moreover, the adsorption and desorption processes can be repeatedly and circularly carried out, carbon dioxide gas generated by human activities can be effectively removed, and the indoor concentration is always maintained in a range that the human body feels comfortable.

Example eight:

in the above embodiment, the control method of the purification apparatus further includes: the desorption command is generated based on the comparison result between the change in the carbon dioxide concentration detected by the carbon dioxide detection device 230 of the purification device and the set value.

In this embodiment, when the change in the carbon dioxide concentration detected by the carbon dioxide detection device 230 is less than or equal to the set value, that is, when the carbon dioxide concentration detected by the carbon dioxide detection device 230 does not decrease any more, it indicates that the purification material cannot adsorb carbon dioxide any more, a desorption command may be generated, and the useless adsorption function may be stopped, and desorption may be performed. When the change in the carbon dioxide concentration detected by the carbon dioxide detection device 230 is higher than the set value, it can be said that the purification material can still adsorb carbon dioxide and can continue to adsorb carbon dioxide.

Specifically, the carbon dioxide detecting device 230 detects the change in the carbon dioxide concentration at every predetermined time, and the change in the carbon dioxide concentration detected by the carbon dioxide detecting device 230 is the difference between the previous detection value and the next detection value.

Of course, in another specific embodiment, the desorption command may be received by the purification apparatus, such as generated by the user by activating a button of the purification apparatus.

Example nine:

on the basis of the sixth or seventh embodiment, the control method of the purification apparatus further includes: controlling the heating component 130 to stop heating based on the condition that the temperature value detected by the first temperature measuring device 240 and/or the second temperature measuring device 250 of the purification device is greater than or equal to the first set temperature value; controlling the heating assembly 130 to continue heating based on the condition that the temperature value detected by the first temperature measuring device 240 of the purification device and/or the second temperature measuring device 250 of the purification device is less than or equal to the second set temperature value; wherein, the first set temperature value is greater than the second set temperature value.

In this embodiment, when the temperature value detected by any one of the first detection device and the second detection device is greater than or equal to the first set temperature value, it is indicated that the temperature of the purification material is already high at this time, and the purification material is easily damaged. And when any temperature value that detects was less than the second when setting for the temperature value in first detection device and the second detection device, it is lower to explain purifying material's temperature this moment, and unable abundant desorption carbon dioxide heats through control heating element 130, is favorable to purifying material to realize quick desorption. Moreover, the temperature of the purifying material is kept between the first set temperature value and the second set temperature value, so that the purifying material can maintain a long-time better desorption state, and the rapid desorption of the purifying material is facilitated.

In a specific embodiment, the first set temperature value and the second set temperature value range from 80 ℃ to 100 ℃. For example, the first set temperature value is 100 ℃ and the second set temperature value is 80 ℃; or the first set temperature value is 98 deg.c and the second set temperature value is 83 deg.c. This is not to be taken as an example.

Example ten:

on the basis of the sixth embodiment, the seventh embodiment, or the eighth embodiment, the control method of the purification apparatus further includes: controlling the heating assembly 130 to stop operating in response to the adsorption instruction; and controlling the first and second valve bodies 180 to be opened, the blower 190 to be operated, and the pump body 220 to be stopped, so that the purification apparatus enters an adsorption state.

In this embodiment, when receiving the suction command, the suction command is responded, such as controlling the heating assembly 130 to stop operating, controlling the first and second valve bodies 180 to open, controlling the fan 190 to operate, and controlling the pump body 220 to stop operating, so as to enter the suction state. Specifically, in the adsorption state, the fan 190 can suck the gas containing high-concentration carbon dioxide in the room into the purification chamber 120, and the gas is adsorbed by the purification material in the purification chamber 120 and then discharged back into the room. Because the purification material can quickly adsorb carbon dioxide, the concentration of the carbon dioxide in the room can be continuously reduced.

Example eleven:

hereinafter, an operation mode of the purification apparatus according to an embodiment of the present invention will be described in detail.

1) An adsorption process:

the heating assembly 130 and the pump body 220 are in a closed state. The first valve body 180 and the second valve body 180 are opened, and the blower fan 190 is started. At this time, the fan 190 sucks the air containing high concentration carbon dioxide in the room into the purification device, and the air is treated by the purification material (such as solid amine) and then discharged back to the room through the first air outlet channel 170. The solid amine can quickly adsorb carbon dioxide, so that the concentration of carbon dioxide in a room is reduced continuously.

2) A desorption process:

when the carbon dioxide detecting device 230 detects that the concentration of carbon dioxide in the air in the first air outlet channel 170 does not decrease any more, the desorption process is started. The first valve body 180 and the second valve body 180 are closed, and the blower 190 is closed. At this time, the heating element 130 and the solid amine are in a sealed space, and are communicated with the outdoor only through the second air outlet channel 210. The heating assembly 130 and the pump body 220 are turned on. When the detected temperature of any one of the first temperature measuring device 240 or the second temperature measuring device 250 is higher than 100 ℃, the heating assembly 130 is closed for over-temperature protection; when the highest temperature of the first temperature measuring device 240 and the second temperature measuring device 250 is lower than 80 ℃, the heating assembly 130 is restarted. Thus, the temperature of the solid amine is always kept at the optimal desorption condition between 80 ℃ and 100 ℃. In the desorption process, the pump body 220 continuously discharges the desorbed carbon dioxide gas to the outside through the second air outlet channel 210.

The adsorption and desorption processes are repeatedly and circularly carried out, so that carbon dioxide gas generated by human activities can be effectively removed, and the indoor concentration is always maintained in a range that the human body feels comfortable.
