In order to ensure the quality of the air blown into the room, the air is usually treated with the help of an air intake device first, so that the air cleanliness reaches a certain standard, and then the air is cooled or heated for use. Common air intake devices can generally perform dust removal and other purification treatments on outdoor air. The dust removal of air intake devices mostly adopts the principle of electrostatic adsorption, that is, dust-containing air is electrically separated when passing through a high-voltage electrostatic field. After the dust particles combine with negative ions and carry negative charges, they tend to discharge and deposit on the anode surface.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1~Figure 3 , which is the first embodiment of the present invention, provides an air-conditioning air intake device that can achieve the effect of dust removal and filtering of the air entering the air conditioner, and includes an air intake mechanism 100.

[0028] Specifically, the air inlet mechanism 100 includes a housing 101, an air inlet pipe 102 is installed on one side of the outside of the housing 101, and an air outlet pipe 103 is installed on the other side of the outside of the housing 101. The air inlet pipe 102 and the air outlet pipe 103 are both connected to the inside of the housing 101. At the same time, the end of the air outlet pipe 103 close to the inside of the housing 101 is connected to a fan 104. The fan 104 is arranged inside the housing 101. The negative pressure generated by the fan 104 can pass the external air through the air inlet mechanism 100 into the cooling or heating system of the air conditioner. The first partition is fixedly installed inside the housing 101. 105, and fixed plates 106 are installed on both sides of the first partition 105, the first partition 105 and the two fixed plates 106 together form a placement space, and a bypass passage 107 is arranged on the outer side of the fixed plate 106, and filters 108, discharge components 109 and dust removal components 110 are installed on the inner sides of the two fixed plates 106 in sequence, and multiple slots are reserved on the inner sides of the two fixed plates 106, and the filters 108, discharge components 109 and dust removal components 110 are arranged in corresponding slots in sequence, and a cover plate 111 is fixed on the top of the casing 101 by screws.

[0029] Furthermore, the discharge element 109 includes a perforated plate 109a with openings evenly distributed thereon, and a discharge grid 109b is arranged inside the openings of the perforated plate 109a. The high-voltage electric field formed by the discharge grid 109b can electrically separate the dust-containing gas passing through the perforated plate 109a, so that the dust particles are combined with negative ions and carry negative charges, so as to facilitate the subsequent cooperation with the dust removal element 110 to remove particulate matter.

[0030] The dust removal component 110 includes a cover shell 110a arranged between two fixed plates 106, and a connecting pipe 110b corresponding to the opening on the orifice plate 109a is integrally arranged on the outer wall of the cover shell 110a on the side close to the orifice plate 109a. The airflow passing through the discharge component 109 can enter the interior of the dust removal component 110 through the connecting pipe 110b. At the same time, an opening is also arranged on the other side of the cover shell 110a, so that the air processed by the dust removal component 110 can smoothly reach the chamber where the outlet pipe 103 and the fan 104 are located, and two groups of dust removal plates 110c are installed inside the cover shell 110a, and the dust removal plates 110c are arranged in an oblique symmetrical manner. At the same time, each dust removal plate 110c carries a positive charge, so that the negatively charged dust particles can be affected by the positive charge and tend to be deposited and collected on the dust removal plate 110c.

[0031] The first partition plate 105 is provided with a first air inlet 105a and a second air inlet 105b in sequence, and the first air inlet 105a and the second air inlet 105b are both provided with control valves to control the opening and closing of the first air inlet 105a and the second air inlet 105b. Meanwhile, the bypass passage 107 is a chamber between the fixed plate 106 and the casing 101. The first air inlet 105a is connected with the placement space formed by the first partition plate 105 and the two fixed plates 106, so that the air can be processed through the filter 108, the discharge element 109 and the dust removal element 110, and finally enter the chamber where the fan 104 is located. The second air inlet 105b is connected with the bypass passage 107, and can directly reach the location of the fan 104 through the bypass passage 107 to enter the cooling or heating system of the air conditioner.

[0032] During use, when the incoming air needs to be processed, the first air inlet 105a is opened and the second air inlet 105b is closed. At this time, the air flow first passes through the filter 108 for initial filtration, and then is ionized by the discharge element 109 to charge the dust particles, and finally enters the dust removal element 110. The dust particles are deposited on the dust removal plate 110c. The clean air passes through the dust removal element 110 and enters the cooling or heating system of the air conditioner through the air outlet pipe 103, thereby completing the dust removal of the external air. When the incoming air does not need to be processed, the second air inlet 105b is opened and the first air inlet 105a is closed, and the external air directly enters the cooling or heating system of the air conditioner through the bypass passage 107 and the air outlet pipe 103.

[0033] In summary, through the coordination of the bypass passage 107 and the path between the two fixed plates 106, the user can switch the working state of the air intake mechanism 100 as needed, thereby achieving energy-saving operation of the air intake mechanism 100 while meeting the user's needs for air purification.

[0034] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a cleaning mechanism 200 for the air-conditioning air inlet device, which solves the problem of excessive dust deposition on the surface of the dust removal plate 110c affecting the adsorption effect of the dust particles.

[0035] Specifically, the cleaning mechanism 200 includes a driving member 201 fixedly installed inside the dust removal member 110, and a cleaning member 202 is movably provided on the outside of the driving member 201, and a power member 203 is also provided at the end of the driving member 201. At the same time, an ash storage member 204 is also provided at the bottom of the casing 101, and a conversion member 205 is provided inside the ash storage member 204.

[0036] Furthermore, the driving member 201 includes a rotating seat 201a fixedly arranged on the inner wall of the cover shell 110a away from the connecting pipe 110b, and a driving rod 201b is rotatably inserted inside the rotating seat 201a, and a driving groove 201c is provided on the outer wall of the driving rod 201b, and a transfer interface 201d is provided in a circular array on the outer edge of the end surface of the driving rod 201b away from the rotating seat 201a, and a connecting head 201e is also integrally provided at the center of the end surface of the driving rod 201b relative to the transfer interface 201d.

[0037] The cleaning member 202 includes a movable frame 202a movably mounted on the outside of the driving rod 201b. The movable frame 202a is composed of a circular ring and cross bars fixedly arranged on both sides thereof. A driving head 202b is integrally arranged on the inner wall of the movable frame 202a. Scrapers 202c are fixedly connected to both sides of the movable frame 202a. The scrapers 202c on both sides are respectively fitted with the dust removal plates 110c arranged on their respective outer sides.

[0038] The power part 203 includes a sleeve 203a which is sleeved on the outside of the connecting head 201e. The outside of the sleeve 203a is integrally connected with a plurality of paddles 203b arranged in a circular array, and a plurality of transfer teeth 203c are also arranged in a circular array on the end surface of the sleeve 203a opposite to the connecting head 201e. At the same time, a top spring 203d is arranged between the sleeve 203a and the connecting head 201e. The top spring 203d can elastically support the sleeve 203a so that there is a certain distance between the adjacent end surfaces of the sleeve 203a and the driving rod 201b. A mating opening 203e is also reserved on the outer wall of the sleeve 203a.

[0039] The ash storage component 204 includes an ash storage chamber 204a connected to the interior of the dust removal component 110, and the bottom of the inner wall of the ash storage chamber 204a is symmetrically installed with an induction spring 204b, the top of the induction spring 204b is fixedly connected with a pressure plate 204c, and the surface of the pressure plate 204c is detachably installed with an ash storage box 204d.

[0040] The conversion member 205 includes a bracket 205a fixed to the pressing plate 204c, and a push plate 205b is integrally connected to the top of the bracket 205a.

[0041] Preferably, the driving groove 201c is spirally arranged along the outer wall of the driving rod 201b, and the driving head 202b on the inner wall of the movable clamp is slidably embedded in the driving groove 201c. Since the scrapers 202c at both ends of the movable frame 202a are in contact with the dust removal plate 110c, the movable frame 202a can only move horizontally along the axial direction of the driving rod 201b. Then, when the driving rod 201b rotates, the driving groove 201c arranged in a spiral manner pushes the driving head 202b, so that the movable frame 202a can perform stable horizontal movement along with the rotation of the driving rod 201b. Therefore, under the setting of the scraper 202c, the dust particles remaining on the dust removal plate 110c can be cleaned, thereby ensuring the normal dust removal use of the dust removal plate 110c in the subsequent process.

[0042] Preferably, the transfer tooth 203c is meshed with the transfer interface 201d, and the undulation direction of the transfer tooth 203c is the same as the rotation direction of the paddle 203b, that is, the extension direction from the lowest point to the highest point of the transfer tooth 203c is the same as the rotation direction of the paddle 203b. This arrangement can ensure the stable meshing of the transfer tooth 203c and the transfer interface 201d in the rotation direction of the paddle 203b, so that when the transfer tooth 203c is meshed with the transfer interface 201d, the drive rod 201b can be rotated with the rotation of the sleeve 203a, so that the sleeve 203a drives the drive rod 201b, thereby realizing the horizontal movement of the cleaning member 202 to clean the dust removal plate 110c. At the same time, when the transfer tooth 203c is disengaged from the transfer interface 201d, the power member 203 is in an idling state and stops driving the drive member 201.

[0043] The push plate 205b is wedge-shaped and is located in the mating opening 203e. The width of the push plate 205b gradually increases from bottom to top. When the dust in the ash box 204d accumulates to a certain amount, the induction spring 204b is compressed by the gravity of the ash box 204d. At this time, the ash box 204d and the pressure plate 204c drop synchronously, so that the push plate 205b is relatively displaced downward relative to the mating opening 203e. As a result, the upper end of the push plate 205b squeezes the mating opening 203e, so that the power member 203 as a whole squeezes the top spring 203d to move in the direction of the driving member 201, and along with the rotation of the power member 203, the transfer tooth 203c is engaged with the transfer interface 201d. At this time, the power of the power member 203 is transferred to the driving member 201, thereby realizing the driving of the driving member 201.

[0044] When in use, the dust removal element 110 electrostatically adsorbs the dust particles contained in the air, and the deposited dust particles fall into the ash storage box 204d through the dust removal plate 110c. As the dust particles in the ash storage box 204d continue to increase, it indicates that the dust removal element 110 has been working for a long time. After working for a long time, dust particles are easily attached to the surface of the dust removal plate 110c, which affects the subsequent dust removal effect. Therefore, the use of the dust removal plate 110c can be judged by the collection status of the dust particles in the ash storage box 204d. State, when the dust particles inside the ash storage box 204d exceed a certain amount, the ash storage box 204d squeezes the induction yellow under the action of gravity, driving the pressure plate 204c and the conversion member 205 to drop synchronously, and at this time, through the cooperation between the push plate 205b and the matching port 203e, the power member 203 completes the power connection with the driving member 201, so that the driving member 201 drives the cleaning member 202 to move and clean the dust removal plate 110c, so as to ensure the efficient dust removal effect of the dust removal plate 110c.

[0045] In summary, the use status of the dust removal plate 110c is estimated by the change in the overall weight of the ash storage box 204d, and the power connection between the power component 203 and the driving component 201 is controlled by means of the gravity of the ash storage box 204d. Therefore, the dust removal plate 110c can be automatically cleaned through the cleaning component 202, thereby ensuring the long-term use effect of the dust removal component 110.

[0046] Example 3, reference Figure 1 to Figure 8 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a cleaning mechanism 200 for the air-conditioning air inlet device, which solves the installation and disassembly problems of the ash storage box 204d, and includes a limiting member 206.

[0047] Specifically, the limiting member 206 includes a limiting plate 206a hingedly arranged on one side of the pressing plate 204c, and a supporting spring 206b is arranged between one end of the limiting plate 206a and the pressing plate 204c.

[0048] Furthermore, the support spring 206b can elastically support the limiting plate 206a, thereby ensuring the stability of the limiting plate 206a when limiting the movement of the ash storage box 204d.

[0049] When in use, the upper end of the limit plate 206a is pressed against the ash box 204d under the elastic force of the support spring 206b on its lower end, thereby cooperating with the ash storage chamber 204a to achieve the purpose of limiting the ash box 204d. When the ash box 204d decreases due to the increase in weight caused by the collection of dust particles, the limit plate 206a moves downward synchronously and contacts the bottom of the ash storage chamber 204a and flips over, thereby releasing the restriction on the ash box 204d, making it convenient for the user to take out the ash box 204d for cleaning. When the ash box 204d is reinstalled, the pressure plate 204c is pressed first to ensure the smooth installation of the ash box 204d. After the installation is completed, the ash box 204d and the pressure plate 204c are quickly reset under the support of the induction spring 204b.

[0050] In summary, by disposing the limiting member 206, the stability of the dust storage box 204d when collecting dust particles can be ensured.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
