Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a dust collecting module and a purifier. Background Art

[0002] As people's living standards improve, their requirements for quality of life are getting higher and higher, and air quality has become an important concern for people. Purifiers, as household appliances for indoor air purification, can effectively absorb, decompose or transform pollutants in the air, such as dust, bacteria, viruses, etc., thereby improving air quality.

[0003] The purifiers on the market that use the electric purification principle generally collect bacteria and viruses in the air on the surface of the filter and the dust collecting plate. After using it for a period of time, the whole machine will sound a cleaning reminder, requiring the user to take out the dust collection module and clean it by themselves to ensure the purification effect of the purifier.

[0004] This method of removing the dust collecting module and then cleaning it is time-consuming and laborious, and there is a risk of secondary infection of bacteria and viruses when cleaning the dust collecting module after long-term use, making the cleaning of the dust collecting module of the existing purifier very inconvenient. Summary of the invention

[0005] Based on this, the present invention aims at the problem that the dust collecting module of the existing purifier is inconvenient to clean, and proposes a dust collecting module and a purifier, which have the technical effect of being easy to clean.

[0006] A dust collection module, comprising:

[0007] A cleaning member having a water supply channel;

[0008] A dust collecting member is spaced apart from the cleaning member, and a dust collecting surface is formed on a side of the dust collecting member facing the cleaning member, and the dust collecting member is configured to adsorb bacterial particles in the air to the dust collecting surface; wherein the cleaning member has a cleaning state, and when the cleaning member is in the cleaning state, the water supply channel is opened, and the dust collecting surface is scrubbed with a first water flow rate.

[0009] Thereby, the bacteria and dust accumulated on the surface of the dust collecting surface for a long time are cleaned, thereby realizing the self-cleaning function of the dust collecting module, making the cleaning of the dust collecting module convenient and simple.

[0010] In one of the embodiments, the cleaning member further comprises an ionization portion;

[0011] The cleaning member has a disinfection state. When the cleaning member is in the disinfection state, the water supply channel opens a second water flow rate and forms water mist, and the ionization unit discharges in a controlled manner until the water mist particles are charged to disinfect the dust collecting surface, wherein the second water flow rate is less than the first water flow rate;

[0012] When the cleaning member is in the cleaning state, the ionization portion stops discharging.

[0013] In this way, the dust collection module provided by the present application can realize the integration of disinfection, sterilization and cleaning, and can be adaptively selected according to the needs in actual operation to meet the use needs. At the same time, because the second water flow rate is less than the first water flow rate, the cleaning part can flush the dust collection part with a large water flow, so that the dust collection module provided by the present application can also achieve good cleaning effect and high cleaning efficiency.

[0014] In one embodiment, the dust collection module further includes a flow regulating valve, which is arranged on the water supply channel and is used to control the water flow of the water supply channel. This facilitates the adjustment of the flow rate in the water supply channel, and ensures that water flows of different flow rates are provided when the cleaning element is in different states. When it is necessary to open the first flow rate, the flow regulating valve controls the water supply channel to spray a high-intensity pressure water column, which is sufficient to allow the water column to flush the dirt on the dust collecting surface. When it is necessary to open the second flow rate, the flow regulating valve controls the water supply channel to spray a small flow rate to form water mist particles. This enables the operation of disinfecting or cleaning the dust collecting surface.

[0015] In one of the embodiments, the dust collecting module includes a high voltage power supply, the high voltage power supply includes a voltage electrode and a ground electrode, the voltage electrode is electrically connected to the ionization part, and the ground electrode is electrically connected to the dust collecting part.

[0016] In one embodiment, when the cleaning member is in the disinfection state for a time longer than a predetermined working time, the cleaning member is controlled to switch from the disinfection state to the cleaning state. When the cleaning member is in the disinfection state for a time longer than a predetermined working time, it indicates that the disinfection time is too long and a certain thickness of dust may be accumulated on the dust collecting surface. At this time, the cleaning member is controlled to switch from the disinfection state to the cleaning state to thoroughly scrub the dust collecting surface to ensure that the dust collecting member is always kept clean.

[0017] In one embodiment, the dust collection module further comprises a controller, and the controller controls the cleaning element to switch between the disinfection state and the cleaning state, thereby realizing intelligent control of the cleaning element.

[0018] In one of the embodiments, the cleaning element is a high-pressure nozzle, the ionization portion is arranged inside the high-pressure nozzle along the axial direction of the high-pressure nozzle, and is used for performing tip discharge on a side of the high-pressure nozzle close to the dust collecting element.

[0019] In one embodiment, the ionization portion includes a plurality of carbon fibers or a plurality of metal wires.

[0020] According to another aspect of the present invention, there is provided a purifier, comprising the dust collection module according to any one of the above embodiments, wherein the dust collection module is assembled in the housing;

[0021] The cleaning member further comprises an ionization unit, and the cleaning member has a disinfection state. When the cleaning member is in the disinfection state, the water supply channel opens a second water flow rate and forms water mist, and the ionization unit is controlled to discharge until the water mist particles are charged to disinfect the dust collecting surface, wherein the second water flow rate is less than the first water flow rate;

[0022] When the cleaning element is in the cleaning state, the ionization unit stops discharging;

[0023] The purifier has a function selection state. When the purifier is in the function selection state, the cleaning element is in the cleaning state or the disinfection state.

[0024] In one of the embodiments, the purifier also has a purification function, and when the purifier is in the purification function, the dust collection module is turned off.

[0025] The dust collecting module includes a cleaning part and a dust collecting part. The cleaning part has a water supply channel. The dust collecting part and the cleaning part are arranged at intervals, and the side of the dust collecting part facing the cleaning part forms a dust collecting surface. The dust collecting part is configured to adsorb bacterial particles in the air to the dust collecting surface, thereby completing the dust collecting operation and purifying the air. The cleaning part has a cleaning state. When the cleaning part is in the cleaning state, the dust collecting surface stops the dust collecting operation, the water supply channel is opened and the surface of the dust collecting surface is brushed with a first water flow rate, thereby cleaning the bacteria and dust accumulated on the surface of the dust collecting surface for a long time, thereby realizing the self-cleaning function of the dust collecting module, making the cleaning of the dust collecting module convenient and simple.

[0036] As described in the background technology, the cleaning problem of air purifiers based on the principle of electric purification has always been a pain point for air purifier users. The existing treatment methods in the market are generally that the purifier will sound a cleaning reminder after being used for a period of time, and the user needs to take out the dust collection module and clean it by himself. However, this treatment method is a troublesome and time-consuming problem for users to clean the module. If it is not taken out for cleaning for a long time, the dirty dust collection module will also cause the performance of the purifier to decay and cause ozone problems during use. Finally, the creepage caused by dirt and other phenomena may even cause the aging of the purifier material and reduce the service life of the purifier. Moreover, the bacteria and viruses collected in the air on the surface of the filter and the dust collecting plate will produce secondary infection bacteria if they are not cleaned for a long time, and manual cleaning in a high-bacteria environment will also produce the risk of secondary infection of bacteria and viruses, making the cleaning of the dust collection module of the purifier very troublesome and impossible to achieve convenient cleaning, while ensuring the safety of users.

[0037] To solve the above problems, see Figure 1 to Figure 2 An embodiment of the present invention provides a dust collecting module 10, including a cleaning member 11 and a dust collecting member 12. The cleaning member 11 has a water supply channel 111. The dust collecting member 12 is spaced apart from the cleaning member 11, and a dust collecting surface 121 is formed on the side of the dust collecting member 12 facing the cleaning member 11. The dust collecting member 12 is configured to adsorb bacterial particles in the air to the dust collecting surface 121, thereby completing the dust collecting operation and purifying the air. The cleaning member 11 has a cleaning state. When the cleaning member 11 is in the cleaning state, the dust collecting surface 121 stops the dust collecting operation, the water supply channel 111 is opened and the surface of the dust collecting surface 121 is brushed with a first water flow rate, thereby cleaning the bacteria and dust accumulated on the surface of the dust collecting surface 121 for a long time, thereby realizing the self-cleaning function of the dust collecting module 10, making the cleaning of the dust collecting module 10 convenient and simple.

[0038] It can be understood that the present application provides the cleaning part 11 to achieve self-cleaning of the dust collecting part 12, and there is no need to manually take out the dust collecting part 12 for manual brushing, and through the control of the cleaning part 11, the dust collecting part 12 can be cleaned at any time. In this way, there is no need to manually take it out for brushing, thereby avoiding the risk of secondary bacterial contamination and ensuring the safety of the user.

[0039] Furthermore, when the dust collecting part 12 is cleaned, a corresponding structure can be provided to recover the sewage flowing down from the dust collecting part 12 to complete the entire cleaning process, without the need to disassemble and take out the dust collecting part 12, and the structure is simple and easy to implement.

[0040] In one embodiment, the cleaning element 11 further includes an ionization unit 112, which can discharge or stop discharging in a controlled manner. When the cleaning element 11 is in a cleaning state, the ionization unit 112 stops discharging, thereby ensuring that the water supply channel 111 can provide a first water flow rate to flush the dust collecting surface 121.

[0041] Furthermore, the cleaning member 11 also has a disinfection state. When the cleaning member 11 is in the disinfection state, the water supply channel 111 opens the second water flow and forms water mist. At this time, the ionization unit 112 discharges and ionizes the air in a controlled manner, generating active groups such as hydroxyl groups, which are adsorbed in the water mist, so that the water mist particles are charged. When the charged water mist particles are spread onto the dust collecting surface 121, the active groups cause the proteins and nucleic acids in the bacterial microorganisms to undergo chemical reactions, which can destroy the microorganisms and disrupt the survival functions of the microorganisms, making them inactive, thereby achieving the effect of killing viruses and bacteria. In this way, the dust collecting surface 121 is disinfected, killing a large number of bacterial particles adsorbed on the dust collecting surface 121.

[0042] In this way, the dust collection module 10 provided in the present application can realize the integration of disinfection, sterilization and cleaning, and in actual operation, an adaptive selection can be made according to the needs to meet the use requirements.

[0043] Moreover, the second water flow rate is smaller than the first water flow rate, and the cleaning member 11 can flush the dust collecting member 12 with a large force of water flow, so that the dust collecting module 10 provided in the present application can also achieve good cleaning effect and high cleaning efficiency.

[0044] In one embodiment, in order to ensure that when the cleaning member 11 is in a disinfection state, the water supply channel 111 opens a second water flow rate, and when the cleaning member 11 is in a cleaning state, the water supply channel 111 opens a first water flow rate, the dust collection module 10 also includes a flow regulating valve 13, and the flow regulating valve 13 is arranged on the water supply channel 111 to control the water flow rate of the water supply channel 111, so as to conveniently adjust the flow rate in the water supply channel 111, and ensure that when the cleaning member 11 is in different states, water flows of different flow rates are provided. When the first water flow rate is required, the flow regulating valve 13 controls the water supply channel 111 to spray a high-intensity pressure water column, which is sufficient to flush the dirt on the dust collection surface 121. When the second water flow rate is required, the flow regulating valve 13 controls the water supply channel 111 to spray a sufficiently small second water flow rate to form water mist particles. Thereby, the dust collection surface 121 is disinfected or cleaned.

[0045] In one embodiment, the dust collection module 10 further includes a water source 14 , and the water supply channel 111 is connected to the water source 14 . The water source 14 is used to supply water into the water supply channel 111 and provide power to drive the water of the water source 14 into the water supply channel 111 and then flow out.

[0046] In one embodiment, the dust collecting module 10 includes a high voltage power supply 15, which includes a voltage electrode and a grounding electrode. The voltage electrode is electrically connected to the ionization part 112 through a wire, and the grounding electrode is electrically connected to the dust collecting part 12 through a wire. When the high voltage power supply 15 gives a high voltage to the ionization part 112 in the cleaning part 11, the ionization part 112 ionizes the air through corona discharge, and sprays water mist in the cleaning part 11 at the same time. Due to the discharge diffusion and particle collision, the water mist particles in the air will be charged and become charged particles. Since the dust collecting part 12 is grounded, the charged water mist particles will be evenly distributed on the dust collecting surface 121 of the dust collecting part 12, and the charged particles will react with the viruses and bacteria adsorbed on the plate, and finally achieve the purpose of disinfection and sterilization.

[0047] Specifically, the cleaning element 11 is a high-voltage nozzle, and the ionization part 112 is arranged inside the high-voltage nozzle along the axial direction of the high-voltage nozzle, and is used to perform tip discharge on the side of the high-voltage nozzle close to the dust collecting element 12. In order to ensure the discharge effect, the ionization part 112 can be composed of multiple filaments with a very small curvature radius, such as carbon fiber, thin metal wire, etc., and is electrically connected to the voltage pole of the high-voltage power supply 15 through a wire, and is placed at the central axis of the high-voltage nozzle for tip discharge.

[0048] In one of the embodiments, when the cleaning member 11 is in the disinfection state for more than a predetermined working time, it indicates that the disinfection time is too long, and a certain thickness of dust may accumulate on the surface of the dust collecting surface 121. At this time, the cleaning member 11 is controlled to switch from the disinfection state to the cleaning state to thoroughly scrub the dust collecting surface 121 to ensure that the dust collecting member 12 is always kept clean.

[0049] In one embodiment, the dust collection module 10 further includes a controller, and the controller controls the cleaning member 11 to switch between a disinfection state and a cleaning state, thereby realizing intelligent control of the cleaning member 11 .

[0050] According to another aspect of the present application, see Figure 3 The present application also provides a purifier 100 , comprising a shell 20 and a dust collecting module 10 according to any one of the above embodiments, wherein the dust collecting module 10 is assembled in the shell 20 .

[0051] The cleaning member 11 has a water supply channel 111 and an ionization unit 112. The cleaning member 11 has a cleaning state. When the cleaning member 11 is in the cleaning state, the dust collecting surface 121 stops collecting dust, the ionization unit 112 stops discharging, and the water supply channel 111 opens a first water flow rate to scrub the surface of the dust collecting surface 121, thereby cleaning the bacteria and dust accumulated on the surface of the dust collecting surface 121 for a long time, thereby realizing the self-cleaning function of the dust collecting module 10. The cleaning member 11 also has a disinfection state. When the cleaning member 11 is in the disinfection state, the water supply channel 111 opens a second water flow rate to form water mist, and the ionization unit 112 discharges in a controlled manner until the water mist particles are charged to disinfect the dust collecting surface 121.

[0052] The purifier 100 has a function selection state. When the purifier 100 is in the function selection state, the cleaning part 11 is in a cleaning state or a disinfection state. In this way, the purifier 100 provided in the present application can realize the self-disinfection and self-cleaning functions of the dust collection module 10 while realizing air purification, so that the cleaning of the dust collection module 10 is simple and the disinfection, sterilization and cleaning are integrated.

[0053] Among them, the second water flow rate is smaller than the first water flow rate, and the cleaning element 11 can flush the dust collecting element 12 with a large force of water flow, so that the purifier 100 provided in the present application can also achieve good cleaning effect and high cleaning efficiency.

[0054] In one embodiment, the purifier 100 also has a purification function. When the purifier 100 is in the purification function, the dust collecting module 10 is turned off. At this time, the dust collecting piece 12 is electrically connected to the voltage pole of the high-voltage power supply 15 through the discharge tungsten wire 30. The dust collecting plate is a metal structure such as mesh metal and sheet metal. At this time, the discharge tungsten wire 30 works, and the high-voltage power supply 15 provides high voltage to the discharge tungsten wire 30, so that the charged polluted particles in the air can be collected by the dust collecting surface 121 of the dust collecting piece 12. At this time, the electrical connection between the high-voltage power supply 15 and the ionization unit 112 is closed, and the ionization unit 112 does not work.

[0055] In this way, the purifier 100 provided by the present application can realize the function selection. When the user's requirement for the purifier 100 is not to purify the polluted air in the air, the purifier 100 is controlled to enter the function selection state. After entering the function selection state, according to the actual use situation, the cleaning part 11 is selected to enter the disinfection state or the cleaning state, so as to self-disinfect or self-clean the dust collecting module 10. When the user's demand is only to purify the air, the purifier 100 is controlled to enter the purification function. At this time, the voltage pole of the dust collecting part 12 and the high-voltage power supply 15 are connected, and the cleaning part 11 is turned off so that it does not work, so that the polluted particles such as viruses in the air are absorbed by the dust collecting part 12.

[0056] Furthermore, the controller includes a main circuit board, and the main circuit board has a control program for controlling the purifier 100. The specific control steps are as follows:

[0057] The user selects whether the purifier 100 needs to enter the purification function;

[0058] If the selection is yes, the controller controls the purifier 100 to enter the purification function, so that the voltage pole of the high-voltage power supply 15 is electrically connected to the dust collecting part 12, and the cleaning part 11 is closed at this time. In this way, the viruses and other pollutant particles present in the air entering the purifier 100 through the air inlet are absorbed by the dust collecting part 12, and then adsorbed onto the dust collecting surface 121, completing the purification function.

[0059] When the purifier 100 performs the purification function for a long time, a large number of virus molecules and dust particles are adsorbed on the dust collecting part 12 and need to be cleaned.

[0060] The user selects whether the purifier 100 needs to enter the purification function;

[0061] If not, the controller controls the purifier 100 to enter the function selection state. At this time, the high-voltage electrical connection between the high-voltage power supply 15 and the dust collecting member 12 is cut off, and the user controls the dust collecting module 10 again.

[0062] If the user chooses to clean the dust collecting part 12, the cleaning part 11 enters the cleaning state, the flow regulating valve 13 adjusts the water supply channel 111 to supply a first water flow, and closes the electrical connection between the high-voltage power supply 15 and the cleaning part 11 and the dust collecting part 12, and the large-flow water column fully flushes the surface of the dust collecting surface 121 to achieve self-cleaning of the dust collecting part 12.

[0063] If the user chooses to disinfect the dust collecting part 12, the cleaning part 11 enters the disinfection state, the flow regulating valve 13 adjusts the water supply channel 111 to open the second water flow to form water mist, and turns on the high-voltage power supply 15 so that the ionization part 112 obtains high voltage, the dust collecting part 12 is grounded, and the ionization part 112 ionizes the air through corona discharge, and sprays water mist in the cleaning part 11 at the same time. Due to the discharge diffusion and particle collision, the water mist particles in the air will be charged and become charged particles. The charged water mist particles are evenly distributed on the dust collecting surface 121 of the dust collecting part 12, and the charged particles interact with the viruses and bacteria adsorbed on the plate, and finally achieve the purpose of disinfection and sterilization.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
