Technical Field

[0001] The present invention relates to the technical field of air purifiers, and in particular to an energy-saving air purifier with easy filter element replacement. Background Art

[0002] As people's living standards improve and their health awareness increases, more and more people begin to pay attention to indoor air quality; long-term exposure to polluted air increases the risk of respiratory infections; air purifiers are used to improve indoor air quality. They mainly filter out particulate matter, sulfur oxides, carbon oxides and other particles dispersed in the air through the filter unit of the air purifier to purify the air.

[0003] In the related art, an air purifier includes a ventilation assembly and a filter assembly located in a housing. The ventilation assembly is used to draw indoor air into the housing and circulate it outside the housing; the filter assembly is used to remove dust and bacteria from the gas circulated into the housing through the ventilation assembly. When the air purifier is placed indoors for a long time to purify the air, it is inconvenient to replace the filter element in the filter unit, and it is difficult to ensure the purification effect of the air purifier. Summary of the invention

[0004] In view of this, the present invention aims to provide an energy-saving air purifier with easy filter element replacement to improve the purification effect of the air purifier.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] An energy-saving air purifier with easy filter element replacement, comprising:

[0007] A partition fixedly connected to the shell so as to divide the shell into a ventilation cavity communicated with the air outlet of the shell and a purification cavity communicated with the air inlet of the shell;

[0008] The partition plate is provided with a through hole, and the through hole is connected with the ventilation cavity and the purification cavity;

[0009] A columnar filter element is arranged in the purification chamber, and an adjusting member for adjusting the distance between the filter element and the partition plate so that the filter element is sealed at the through hole is arranged between the bottom end of the filter element and the housing;

[0010] The shell comprises a purification chamber cover plate, and the purification chamber cover plate is detachably connected to the shell to enable the filter element to be taken in and placed in the purification chamber.

[0011] Furthermore, the adjusting member comprises:

[0012] A limiting tube, vertically fixedly connected to the bottom plate in the shell;

[0013] An adjusting cylinder, the opening end of which is slidably inserted into the limiting tube;

[0014] The elastic member is located between the limiting tube and the adjusting cylinder, so that the adjusting cylinder pushes the bottom plate of the filter element to form the top frame of the filter element to be slidably inserted into the through hole, thereby forming a sealed connection between the filter element and the partition.

[0015] Furthermore, a flow guide cover fixedly connected to the inner wall of the shell is provided in the purification chamber, the flow guide cover and the shell are spaced apart to form a flow guide chamber, and the flow guide chamber is communicated with the air inlet;

[0016] The air guide cover is formed with an exhaust port, and the exhaust port is directly opposite to the filter element along the axial direction of the filter element;

[0017] The filter element is a cylindrical structure;

[0018] A ball is rotatably embedded in the top plate of the regulating cylinder, and the ball abuts against the center of the bottom plate of the filter element.

[0019] Furthermore, a plurality of fan blades are evenly distributed along the circumference of the filter element between the top frame and the bottom plate of the filter element.

[0020] Furthermore, a retaining ring is fixedly connected to the top frame of the filter element along the radial direction of the filter element, and baffles are equidistantly arranged on the circumferential side wall of the retaining ring, and the baffles are vertically fixed to the retaining ring.

[0021] Furthermore, the baffle is arranged at an angle and the lower end of the baffle is the front end of the filter element when it rotates.

[0022] Furthermore, the elastic member is a spring.

[0023] Furthermore, a ferromagnetic gasket is provided in the through hole, and the gasket is embedded in the partition;

[0024] A plurality of permanent magnets are fixedly connected at equal intervals along the circumference of the top frame of the filter element.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The energy-saving air purifier with easy filter element replacement described in the present invention provides an adjusting piece under the filter element to facilitate adjusting the distance between the filter element and the partition. When the filter element needs to be replaced, the purification chamber cover plate only needs to be removed, and the distance between the filter element and the partition is adjusted by the adjusting piece to achieve the replacement of the filter element. The filter element can be easily replaced, and the filter element can be replaced regularly to improve the purification effect of the air purifier.

[0027] When the filter element is in the assembled state, the elastic part pushes the limit tube, so that the limit tube pushes the filter element to seal the filter element and the partition; when replacing the filter element, the filter element is held downward by hand, and the elastic part compresses the top frame of the filter element and separates it from the partition, thereby realizing the removal and replacement of the filter element.

[0028] A guide cover connected to the shell is provided to form a guide cavity, and the air to be purified enters the guide cavity through the air inlet and is discharged through the exhaust port. When the purification power of the air purifier is adjusted to a larger level, the air output of the exhaust port increases accordingly. At this time, in combination with the ball bearing, under the action of the airflow discharged from the exhaust port, the filter element rotates with its length center line as the rotation axis to reduce the noise generated by the air to be purified directly blowing the filter element when the dust collector is running at high power; at the same time, the rotation of the filter element can prevent the filter element from purifying the air on only one side or part of the side, thereby increasing the service life of the filter element and improving the air purification effect.

[0029] By arranging fan blades around the filter element, the filter element can be easily rotated when the gas is discharged from the exhaust port.

[0030] By arranging a baffle ring at the top frame, when the baffle ring abuts against the partition, the flow path of the gas is increased, the sealing between the filter element and the partition is improved, and the air flows to the ventilation cavity after passing through the filter element, thereby improving the air quality at the purification port; a baffle plate is arranged outside the baffle ring, and when the filter element rotates, the baffle plate rotates to stir the circumferential air to form an airflow, thereby reducing the gas flow between the partition and the top frame, and further improving the sealing between the filter element and the partition.

[0031] By setting the baffle to rotate at an angle, and setting the lower end of the baffle to be the front end of the filter element when it rotates, that is, the lower end of the baffle is the initial windward end of the baffle when it rotates with the baffle ring, when the baffle ring drives the baffle to rotate, under the action of the airflow and the inclined baffle, a downward pressure is generated on the filter element, thereby making the top plate of the baffle ring gap between the partition plate to avoid direct contact, thereby reducing the resistance of the filter element when it rotates.

[0032] By setting the elastic member as a spring, the elastic deformation of the elastic member is increased, and because the spring has good anti-fatigue performance, the use stability of the adjusting member is also improved.

[0033] By arranging a ferromagnetic gasket in the through hole and arranging permanent magnets equidistantly around the filter element, the filter element can be prevented from deflecting under the support of the ball, thereby preventing the filter element from wearing against the partition when rotating.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0062] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0063] The present embodiment relates to an energy-saving air purifier that is easy to replace the filter element, so that the filter element 4 in the air purifier can be replaced regularly to improve the purification effect of the air purifier.

[0064] In terms of overall structure, Figures 1 to 3 As shown, the energy-saving air purifier which is easy to replace the filter element comprises: a partition plate 2 which is fixedly connected to the shell 1 so that the shell 1 is separated into a ventilation chamber 1a connected to the air outlet 101 of the shell 1 and a purification chamber 1b connected to the air inlet 102 of the shell 1; the partition plate 2 is provided with a through hole 201, and the through hole 201 connects the ventilation chamber 1a and the purification chamber 1b; a columnar filter element 4 is arranged in the purification chamber 1b, and an adjusting member 3 for adjusting the distance between the filter element 4 and the partition plate 2 so that the filter element 4 is sealed at the through hole 201 is arranged between the bottom end of the filter element 4 and the shell 1; the shell 1 comprises a purification chamber cover plate 103, and the purification chamber cover plate 103 is detachably connected to the shell 1 to constitute the taking and placing of the filter element 4 in the purification chamber 1b.

[0065] By setting an adjusting member 3 under the filter element 4, it is convenient to adjust the distance between the filter element 4 and the partition 2. When the filter element 4 needs to be replaced, it is only necessary to remove the purification chamber cover 103, and then adjust the distance between the filter element 4 and the partition 2 by the adjusting member 3, so that the filter element 4 can be replaced. The filter element 4 can be easily replaced, and the filter element 4 can be replaced regularly to improve the purification effect of the air purifier.

[0066] Based on the overall introduction above, in this embodiment, a fan is provided in the ventilation chamber 1a to suck the air to be purified from the air inlet 102 into the purification chamber 1b, and transmits the air to the ventilation chamber 1a after being filtered by the filter element 4 and discharged from the air outlet 101. The housing 1 as a whole can be cylindrical or rectangular columnar. In this embodiment, the housing 1 is preferably set as a rectangular columnar structure. On this basis, the purification chamber cover plate 103 is detachably connected to the housing 1 as one of the side plates of the housing 1. The specific detachable connection method can be selected by clamping or hanging or using screws to thread the purification chamber cover plate 103 with the housing 1.

[0067] For the purpose of facilitating the adjustment of the distance between the filter element 4 and the partition plate 2, as Figures 3 to 6 As shown, the adjusting member 3 includes a limiting tube 301, an adjusting cylinder 302 and an elastic member 303; the limiting tube 301 is vertically fixedly connected to the bottom plate in the housing 1; the adjusting cylinder 302 is a tubular structure with one end closed, and the open end of the adjusting cylinder 302 is slidably inserted into the limiting tube 301; the elastic member 303 is located between the limiting tube 301 and the adjusting cylinder 302, and the elastic member 303 enables the adjusting cylinder 302 to push the bottom plate of the filter element 4 to form a top frame 401 of the filter element 4 to be slidably inserted into the through hole 201, thereby forming a sealed connection between the filter element 4 and the partition 2.

[0068] When the filter element 4 is in the assembled state, the elastic member 303 pushes the limiting tube 301, so that the limiting tube 301 pushes the filter element 4 to make the filter element 4 and the partition 2 sealed; when replacing the filter element 4, the filter element 4 is held by hand to apply a downward force, and the elastic member 303 compresses the top frame 401 of the filter element 4 to separate it from the partition 2, thereby realizing the removal and replacement of the filter element 4.

[0069] As a specific implementation, the elastic member 303 is preferably a spring. By setting the elastic member 303 as a spring, the elastic deformation of the elastic member 303 is increased, and the use stability of the adjustment member 3 is also improved because the spring has good anti-fatigue performance.

[0070] In order to increase the service life of the filter element 4, Figures 4 to 6As shown, a guide cover 5 fixedly connected to the inner wall of the housing 1 is provided in the purification chamber 1b, and the guide cover 5 is spaced from the housing 1 to form a guide chamber 5a, which is communicated with the air inlet 102; the guide cover 5 is formed with an exhaust port 501, and the exhaust port 501 is directly opposite to the filter element 4 along the axial direction of the filter element 4. The filter element 4 is a cylindrical structure; a ball 6 is rotatably embedded in the top plate of the adjustment cylinder 302, and the ball 6 abuts against the center of the bottom plate of the filter element 4.

[0071] A guide chamber 5a is formed by setting a guide cover 5 connected to the outer shell 1, so that the air to be purified enters the guide chamber 5a through the air inlet 102 and is discharged through the exhaust port 501. When the purification power of the air purifier is adjusted to be larger, the air output of the exhaust port 501 increases accordingly. At this time, combined with the ball 6, under the action of the airflow discharged from the exhaust port 501, the filter element 4 rotates with the center line of its length direction as the rotation axis to reduce the noise generated by the air to be purified directly blowing the filter element 4 when the dust collector is running at high power; at the same time, the rotation of the filter element 4 can avoid the filter element 4 purifying the air on only one side or part of the side, thereby increasing the service life of the filter element 4 and improving the air purification effect.

[0072] On the basis of setting the deflector 5 and the ball 6, as Figures 7 to 9 As shown, in order to facilitate the rotation of the filter element 4, a plurality of blades 7 are equally spaced between the top frame 401 of the filter element 4 and the bottom plate along the circumference of the filter element 4. By arranging the blades 7 around the filter element 4, when the gas is discharged from the exhaust port 501, the filter element 4 can be easily rotated.

[0073] In order to improve the sealing between the filter element 4 and the partition 2, as Figures 8 to 9 As shown, a baffle ring 8 is fixedly connected to the top frame 401 of the filter element 4 along the radial direction of the filter element 4, and baffles 801 are arranged equidistantly on the circumferential side wall of the baffle ring 8, and the baffle 801 is vertically fixed to the baffle ring 8. By arranging the baffle ring 8 at the top frame 401, when the baffle ring 8 abuts against the partition 2, the flow path of the gas is increased, the sealing between the filter element 4 and the partition 2 is improved, and the air flows to the ventilation cavity 1a after passing through the filter element 4, thereby improving the air quality of the purified port. A baffle 801 is arranged outside the baffle ring 8. When the filter element 4 rotates, the baffle 801 rotates to stir the circumferential air to form an airflow, thereby reducing the gas flow between the partition 2 and the top frame 401, and further improving the sealing between the filter element 4 and the partition 2.

[0074] Based on the setting of the baffle ring 8 and the baffle plate 801, in order to reduce the resistance of the filter element 4 when it rotates, the baffle plate 801 is tilted and the lower end of the baffle plate 801 is the front end of the filter element 4 when it rotates. By setting the baffle plate 801 to rotate tilted, and setting the lower end of the baffle plate 801 to be the front end of the filter element 4 when it rotates, that is, the lower end of the baffle plate 801 is the initial windward end of the baffle plate 801 when it rotates with the baffle ring 8, when the baffle ring 8 drives the baffle plate 801 to rotate, under the action of the airflow and the tilted baffle plate 801, a downward pressure is generated on the filter element 4, thereby making the top plate of the baffle ring 8 gap between the partition plate 2 to avoid direct contact, thereby reducing the resistance of the filter element 4 when it rotates; at the same time, the airflow formed by the rotation of the baffle plate 801 can still reduce the gas flow between the baffle ring 8 and the partition plate 2.

[0075] In order to avoid friction between the filter element 4 and the partition 2 when the filter element 4 rotates, Figures 7 to 9 As shown, wear is avoided; a ferromagnetic gasket 9 is arranged in the through hole 201, and the gasket is embedded in the partition 2; a plurality of permanent magnets 901 are fixedly connected equidistantly along the top frame 401 of the filter element 4 in the circumferential direction.

[0076] By arranging a ferromagnetic gasket 9 in the through hole 201 and arranging permanent magnets 901 equidistantly around the filter element 4, the filter element 4 can be supported by the balls 6 without being displaced or skewed. During assembly, a micro gap exists between the top frame 401 of the filter element 4 and the partition 2, thereby preventing the filter element 4 from wearing against the partition 2 during rotation.

[0077] The energy-saving air purifier with easy filter element replacement described in the present application is provided with an adjusting member 3 under the filter element 4 to adjust the distance between the filter element 4 and the partition 2. When the filter element 4 needs to be replaced, the purification chamber cover 103 only needs to be removed, and the distance between the filter element 4 and the partition 2 can be adjusted by the adjusting member 3 to replace the filter element 4. The filter element 4 can be easily replaced and replaced regularly to improve the purification effect of the air purifier.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
