[0049] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] In order to facilitate understanding of the HVAC filter device and HVAC equipment provided by the utility model, its application background is first introduced. In the process of introducing fresh air, the HVAC equipment needs to use a filter device to filter the air. In the related art, the HVAC filter device generally includes a filter device housing and a dust collecting plate. The dust collecting plate fixedly connected to the filter device housing can filter dust in the air.

[0051] However, in the above-mentioned related technologies, although the dust collecting plate can filter the dust in the air, after long-term use, the adsorbed dust will cause the filtering effect of the dust collecting plate to deteriorate, and the existence of the filter device shell makes it difficult to clean the dust on the dust collecting plate, affecting the working efficiency of the HVAC.

[0052] Based on the above problems, the utility model provides a warm through filtering device and HVAC equipment, which can clean dust conveniently and quickly, ensure the filtering effect, and further ensure the working efficiency of the HVAC.

[0053] In view of the above problems, the following Figure 1-Figure 5 The utility model describes a warm pass filter device and a heating, ventilation and air conditioning equipment.

[0054] Reference Figures 1 to 3A warm pass filtering device comprises a shell 1, an air inlet plate 2, a filter assembly 3, a dust cleaning assembly 4 and a collecting assembly 5; wherein a filter chamber is provided in the shell 1, and an opening is provided on one side of the filter chamber; the air inlet plate 2 covers the opening of the filter chamber, and an air inlet 20 is provided on the air inlet plate 2; the filter assembly 3 comprises a filter plate 30 arranged in the filter chamber, and the filter plate 30 is located on the path of the fresh air entering from the air inlet 20, and is used to filter the fresh air; the dust cleaning assembly 4 comprises a striking part located in the filter chamber, and the striking part can reciprocate in a direction close to or away from the filter assembly 3, so as to strike the filter assembly 3; a dust cleaning port 10 connected to the filter chamber is provided at the bottom of the shell 1, and the collecting assembly 5 is detachably connected to the dust cleaning port 10.

[0055] In a specific application scenario, the above-mentioned warm-pass filter device is used in HVAC equipment. Fresh air is introduced into the filter chamber through the air inlet 20 on the air inlet plate 2. The filter plate 30 is located on the path of fresh air. The fresh air is filtered when passing through the filter plate 30. The dust and other impurities filtered out will be partially adsorbed on the filter plate 30. In order to prevent dust from affecting the filtering effect of the filter plate 30, the dust adsorbed on the filter plate 30 is cleaned by the dust cleaning component 4 after a period of use. Specifically, the striking part of the dust cleaning component 4 is moved to strike the filter plate 30. The filter plate 30 is vibrated by the striking and the adsorbed dust is shaken off. The shaken dust falls into the collection component 5 through the dust cleaning port 10 under the action of gravity. Then the collection component 5 is regularly disassembled to clean the dust. Compared with the related art, the dust on the filter plate 30 can be cleaned conveniently and quickly, effectively avoiding the influence of the adsorbed dust on the filtering effect of the filter device, thereby ensuring the working efficiency of the HVAC.

[0056] In some optional embodiments of the present invention, the size, shape and material of the shell 1 can be configured in combination with actual needs and application scenarios. Correspondingly, the air inlet plate 2 can be designed in combination with the specification parameters of the shell 1.

[0057] In a specific embodiment of the utility model, the side opening of the filter chamber is rectangular as a whole, the air inlet plate 2 is configured as a rectangular plate and covers the side opening of the filter chamber, and the air inlet plate 2 is fixedly connected to the shell 1. Specifically, the air inlet plate 2 and the shell 1 can be fixed by welding, or connected by connecting components such as bolts. The overall size of the air inlet plate 2 is slightly larger than the side opening of the filter chamber, so that the air inlet plate 2 can be used as a part of the warm pass filter device connected to other equipment. The fresh air is introduced into the filter chamber through the air inlet 20 on the air inlet plate 2. In order to preliminarily filter the fresh air, a grille is provided on the air inlet 20 of the air inlet plate 2.

[0058] The specific structure and working principle of the filter plate 30 can refer to the existing technology, and the specific specifications and parameters can be designed according to actual needs; the striking part of the cleaning component 4 achieves the purpose of cleaning by striking the filter plate 30, and the cleaning component 4 can be connected to the air inlet plate 2 or to the shell 1. The specific selection can be made according to actual needs, as long as the desired cleaning effect can be achieved.

[0059] In a specific embodiment of the present invention, referring to Figure 4 , the dust cleaning component 4 is connected to the air inlet plate 2, specifically, the dust cleaning component 4 is connected to the middle position of the air inlet plate 2, and two air inlets 20 are provided, and the two air inlets 20 are symmetrically arranged on both sides of the dust cleaning component 4. The dust cleaning component 4 specifically also includes a connecting rod 40 and a first elastic member 41; wherein, the connecting rod 40 is slidably arranged through the air inlet plate 2, so that one end of the connecting rod 40 is located in the filter cavity, and the other end is located outside the filter cavity, and the above-mentioned striking portion is connected to the end of the connecting rod 40 located in the filter cavity; the first elastic member 41 is elastically matched with the connecting rod 40, and driven by the elastic force of the first elastic member 41, the connecting rod 40 moves toward the filter cavity, so that the striking portion contacts the filter plate 30. During the cleaning process, the connecting rod 40 is pulled to make the striking part move away from the filter plate 30, and then the connecting rod 40 is released. Under the elastic force of the first elastic member 41, the connecting rod 40 moves quickly toward the filter plate 30 so that the striking part strikes the filter plate 30. The filter plate 30 is vibrated by the striking and shakes off the dust.

[0060] In a specific embodiment of the utility model, the striking part includes an extension plate 42 and a striking head 43; wherein the extension plate 42 is fixedly connected to one end of the connecting rod 40 located in the filter chamber, the extension plate 42 is perpendicular to the connecting rod 40 and arranged along the length direction of the filter plate 30; there are multiple striking heads 43 and they are arranged on the other side of the extension plate 42 relative to the connecting rod 40, specifically, the multiple striking heads 43 are evenly arranged along the length direction of the extension plate 42. Through the extension plate 42 and the multiple striking heads 43 arranged along the length direction of the filter plate 30, during the striking process, on the one hand, the force on the filter plate 30 can be made more uniform, effectively avoiding the problem of damage to the filter plate 30 due to local force, and on the other hand, all parts of the filter plate 30 can be struck comprehensively to ensure the dust cleaning effect.

[0061] Specifically, the striking head 43 is made of rubber material to further reduce damage to the filter plate 30 during the striking process.

[0062] Specifically, one end of the connecting rod 40 outside the filter chamber is connected with a handle 44 to facilitate the staff to lift the connecting rod 40.

[0063] In order to ensure the sealing performance, in a specific embodiment of the utility model, the dust cleaning assembly 4 further includes an elastic sealing sleeve 45 sleeved on the outside of the connecting rod 40, one end of the elastic sealing sleeve 45 is fixed and sealed to the air inlet plate 2, and the other end is fixed and sealed to the connecting rod 40. Specifically, the elastic sealing sleeve 45 is formed as a bellows-like structure made of a flexible material such as a rubber material, so that the elastic sealing sleeve 45 has a margin for telescopic movement, and does not affect the movement of the connecting rod 40 while playing a sealing role.

[0064] In a specific embodiment of the utility model, the first elastic member 41 is a first spring, which is sleeved outside the connecting rod 40 and located in the elastic sealing sleeve 45; one end of the first spring is fixedly connected to the air inlet plate 2, and the other end is connected to the connecting rod 40 or the elastic sealing sleeve 45. In the process of pulling the connecting rod 40, the first spring is stretched by the tension, and in the process of loosening the connecting rod 40, the connecting rod 40 moves quickly under the action of the first spring, so that the striking head 43 strikes the filter plate 30.

[0065] Of course, the first elastic member 41 includes but is not limited to the above-mentioned structure and arrangement method. The first elastic member 41 with other structures or arranged in other ways is also applicable, as long as it can drive the connecting rod 40 to quickly reset so that the striking part can have a striking effect on the filter plate 30.

[0066] The structure of the collecting assembly 5 and the connection method with the housing 1 will be described in detail below with reference to the accompanying drawings.

[0067] Reference Figure 2 and Figure 5 The collecting assembly 5 includes a collecting box 50, and a collecting port is provided on the collecting box 50, and the collecting port corresponds to the position of the dust cleaning port 10. When the filter plate 30 is hit, the dust falling is stored in the collecting box 50 through the dust cleaning port 10 and the collecting port.

[0068] In order to facilitate the installation and removal of the collection box 50, the collection assembly 5 also includes a slider 51 connected to the collection box 50. The housing 1 is provided with a slide groove 12, and the end of the slide groove 12 is provided with an opening. The slider 51 can be embedded in the slide groove 12 from the end opening of the slide groove 12. Specifically, the cross section of the slider 51 can be T-shaped, dovetail-shaped, etc., and it is arranged along the length direction of the collection box 50, and can be arranged on one side of the collection box 50 or on both sides along the width direction; the cross-sectional shape of the slide groove 12 is adapted to the slider 51, and the collection box 50 can be connected to the ash cleaning port 10 of the housing 1 through the mutually embedded slide groove 12 and the slider 51, and the installation and removal of the collection box 50 is convenient.

[0069] In order to improve the stability of the collection box 50 installation, to prevent the collection box 50 from slipping out along the end opening of the slide groove 12, refer to Figure 2A movable baffle 13 is connected to the position of the housing 1 corresponding to the end opening of the chute 12, and the movable baffle 13 can move relative to the housing 1 and be misaligned with the end opening of the chute 12. In practical applications, after the collection box 50 is installed at the ash cleaning port 10, the movable baffle 13 is stopped at the end opening of the chute 12 to prevent the slider 51 from falling out of the chute 12. When removing the collection box 50, the movable baffle 13 is misaligned with the end opening of the chute 12, and then the collection box 50 is pulled outward to achieve the removal of the collection box 50.

[0070] It can be understood that the slide groove 12 can be open at one end or at both ends. When the slide groove 12 is open at one end, a movable baffle 13 is provided. When the slide groove 12 is open at both ends, a movable baffle 13 can be provided at the openings at both ends of the slide groove 12 respectively.

[0071] In this embodiment, one end of the slide groove 12 is provided with an opening, and the other end is closed. The movable baffle 13 is provided at the end opening of the slide groove 12, and the other end is connected to the fixed baffle 14. When the collection box 50 is connected to the cleaning port 10 of the shell 1, one end thereof is in contact with the fixed baffle 14, and the other end is in contact with the movable baffle 13.

[0072] In a specific embodiment of the utility model, the movable baffle 13 is connected to the shell 1 through a movable connection component; the movable connection component includes a limiting slide groove, a limiting slider and a second elastic member; wherein the limiting slide groove is opened on the shell 1, and the extension direction of the slide groove 12 is parallel to the opening direction of the cleaning port 10; the limiting slider is slidably connected to the limiting slide groove, and the movable baffle 13 is connected to the limiting slider; the second elastic member is elastically matched with the limiting slider, and under the drive of the second elastic member, the movable baffle 13 is stopped at the end opening of the slide groove 12.

[0073] Specifically, the cross-sectional size of the limiting slide groove is not smaller than that of the movable baffle 13 , so that when the movable baffle 13 is misaligned with the open end of the slide groove 12 , the movable baffle 13 can be retracted into the limiting slide groove.

[0074] Specifically, the second elastic member adopts a second spring, one end of the second spring abuts against the end wall of the limiting slide groove, and the other end oppositely abuts against the limiting slider, and the second spring is in a compressed state. In this way, driven by the elastic force of the second spring, the movable baffle 13 extends out of the limiting slide groove and stops at the end opening of the slide groove 12.

[0075] In actual work, although the dust adsorbed on the filter plate 30 can be effectively removed by the dust cleaning component 4, it is inevitable that some dust will adhere to the filter plate 30 and be difficult to fall off, which will also have a certain impact on the filtering effect of the filter plate 30 after long-term use. In this case, the filter plate 30 needs to be disassembled and cleaned. In addition, when the filter plate 30 is damaged, the filter plate 30 also needs to be disassembled from the filter cavity and replaced. Therefore, the convenience of disassembly and assembly of the filter plate 30 is also particularly important.

[0076] For the above problems, refer to Figures 1 to 3 In a specific embodiment of the present invention, a slot 11 connected to the filter cavity is provided on the housing 1, and the filter plate 30 is detachably plugged into the filter cavity through the slot 11. In this way, the filter plate 30 can be quickly installed and removed by plugging and unplugging the filter plate 30.

[0077] Specifically, the slot 11 is opened on the upper side of the housing 1; the inner wall of the filter cavity is provided with a first stopper 15 and a second stopper 16, the first stopper 15 and the second stopper 16 are arranged at intervals along the width direction of the slot 11, and the space between the first stopper 15 and the second stopper 16 corresponds to the position of the slot 11, and the first stopper 15 and the second stopper 16 are used to respectively fit the opposite sides of the filter plate 30. When installing the filter plate 30, the filter plate 30 is inserted into the filter cavity from the slot 11, and the first stopper 15 and the second stopper 16 can constrain and limit the filter plate 30, thereby improving the stability of the filter plate 30 installed in the filter cavity.

[0078] Specifically, the first stopper 15 is arranged in a frame shape around the inner wall of the filter chamber. After the filter plate 30 is installed in the filter chamber, the frame-shaped first stopper 15 fits with the filter plate 30, so that it can provide support for the filter plate 30 and also play a sealing role, so that the introduced fresh air can be filtered through the filter plate 30; the second stopper 16 is plate-shaped and two are provided. The two second stops 16 are respectively located at the two ends of the filter chamber along the length direction, and compared with the first stopper 15, the second stopper 16 is closer to the air inlet, and is used to cooperate with the first stopper 15 to constrain and limit the filter plate 30.

[0079] In order to effectively prevent the problem of outside air entering the filter cavity from the slot 11, the side of the filter plate 30 used for plugging and mating with the slot 11 is the first side, and the other opposite side is the second side. The second side of the filter plate 30 is fixedly connected with a sealing plate 31, and the size of the sealing plate 31 is not less than the size of the slot 11. When the filter plate 30 is plugged into the filter cavity, the sealing plate 31 can play a role in closing the slot 11.

[0080] In order to ensure the sealing performance of the sealing plate 31, the warm pass filter device also includes a connecting structure for connecting the sealing plate 31 and the shell 1; the connecting structure includes a clamping plate 32 and a clamping groove 17; wherein the clamping plate 32 is elastically connected to both ends of the sealing plate 31 along the length direction, and the end of the clamping plate 32 away from the sealing plate 31 is formed as a hook end 320 bent inward; the clamping groove 17 is arranged on the shell 1, and when the filter plate 30 is inserted into the filter cavity, the hook end 320 corresponds to the position of the clamping groove 17 and is elastically clamped in the clamping groove 17.

[0081] Specifically, the card plate 32 can be made of a plastic plate or a metal plate so that it has a certain elastic modulus. When the filter plate 30 is installed, the card plate 32 is elastically deformed outward. After the filter plate 30 is installed, the hook end 320 corresponds to the slot 17, and the card plate 32 restores its deformation so that the hook end 320 is engaged in the slot 17. When removing the filter plate 30, the card plate 32 is bent outward, the card plate 32 is deformed so that the hook end 320 is disengaged from the slot 17, and then the filter plate 30 can be pulled out of the slot 11.

[0082] It should be noted that the technical features in the embodiments of the present invention can be combined without conflict.

[0083] The HVAC equipment provided by the present invention is described below. The HVAC equipment described below and the warm ventilation filter device described above can be referred to each other.

[0084] A heating, ventilation and air conditioning equipment comprises the above-mentioned warm ventilation and air conditioning filtering device.

[0085] The novelty of the utility model is that the above-mentioned warm-pass filter device is used for HVAC equipment, and fresh air is introduced into the filter chamber through the air inlet 20 on the air inlet plate 2, and the filter plate 30 is located on the path of fresh air. When the fresh air passes through the filter plate 30, it is filtered, and the dust and other impurities filtered out will be partially adsorbed on the filter plate 30. In order to prevent dust from affecting the filtering effect of the filter plate 30, the dust adsorbed on the filter plate 30 is cleaned by the dust cleaning component 4 after a period of use. Specifically, the striking part of the dust cleaning component 4 is moved to strike the filter plate 30, and the filter plate 30 is vibrated by the striking to shake off the adsorbed dust. The shaken dust falls into the collection component 5 through the dust cleaning port 10 under the action of gravity, and then the collection component 5 is regularly disassembled to clean the dust. Compared with the related art, the dust on the filter plate 30 can be cleaned conveniently and quickly, effectively avoiding the influence of the adsorbed dust on the filtering effect of the filter device, thereby ensuring the working efficiency of the HVAC.
