Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to a purification component disassembly and assembly structure and an air purifier. Background Art

[0002] As people's living standards improve, air purifiers are becoming an essential household appliance. Existing air purifiers typically use mechanical filters to remove particulate matter from the air. These filters capture particles primarily through direct interception and inertial collision. To improve purification efficiency, the density of the filter must be increased. However, high-density filters have low structural strength, a short service life, and require regular replacement.

[0003] To avoid the need for filter replacement, electrostatic air purifiers have been invented. Their principle is electrostatic dust collection. The core purification structure generally consists of a generator and a collector. The generator actively releases high voltage electricity into the air, ionizing it and charging the dust. The collector, consisting of a set of parallel metal plates with opposite charges, attracts and adheres to the charged dust, thereby purifying the air.

[0004] However, the single-time purification efficiency of the electrostatic air purifier is low. The single-time purification efficiency of a new machine or a dust collecting plate that has just been cleaned is generally around 50% at most. As the dust collecting plate becomes dirty, the single-time purification efficiency will gradually decrease. Therefore, it is necessary to clean the integrated board frequently. As mentioned above, the dust collecting plate is the collecting electrode, which is generally a metal structure, and the dust collecting plate and other purification structures together constitute a purification component. When cleaning, the entire purification component needs to be removed from the frame. Due to the heavy weight of the purification component, it is inconvenient for users to operate. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem of inconvenient disassembly and assembly of the purification component of the air purifier in the prior art, thereby providing a purification component disassembly and assembly structure and an air purifier.

[0006] In order to solve the above problems, the present invention provides a purification component disassembly and assembly structure, including a frame body, the frame body forming an accommodating space, the purification component is arranged in the accommodating space, and a rolling element is provided at the wall of the accommodating space supporting the purification component.

[0007] Furthermore, the frame is provided with an opening at a side surface corresponding to the accommodating space, and the purification component can be pushed and pulled into the accommodating space through the opening.

[0008] Furthermore, a mounting portion is provided on the frame, and the rolling element is provided on the mounting portion, with a rolling end thereof abutting against the purification component.

[0009] Furthermore, the rolling element is arranged on the bottom end surface of the frame.

[0010] Furthermore, the rolling element is a ball.

[0011] Furthermore, a plurality of the mounting portions are evenly arranged on the bottom surface along the movement direction of the purification component.

[0012] Furthermore, the mounting portion includes a groove formed on the frame, wherein a portion of the ball is accommodated in the groove, and a clamping arm formed at a notch of the groove relative to the groove, wherein the clamping arm is clamped on the ball.

[0013] The purification component disassembly and assembly structure of the present invention further includes a guide portion provided on the purification component and the frame.

[0014] Furthermore, the guide portion includes a guide rail and / or a guide groove provided on the bottom end surface, and the guide groove and / or guide rail correspondingly provided on the purification component, and the guide groove is adapted to the guide rail.

[0015] Furthermore, the guide rail is arranged between two adjacent rows of rolling elements, and the two rows of rolling elements are symmetrically arranged relative to the guide rail.

[0016] The evolution component disassembly and assembly structure of the present invention further includes a clamping portion provided on the purification component and the frame.

[0017] Furthermore, the clamping portion includes a buckle and / or a clamping slot provided on the bottom end surface, and the clamping slot and / or buckle correspondingly provided on the purification component.

[0018] The present invention also provides an air purifier including any of the above-mentioned purification component disassembly and assembly structures.

[0019] Furthermore, when the purification component is in a preset installation position, a handle is provided on the end surface close to the opening.

[0020] The air purifier in the present invention further comprises a cover plate which is detachably arranged at the opening to cover the opening.

[0021] Furthermore, the air purifier is an electrostatic air purifier.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The purification component disassembly and assembly structure of the present invention includes a frame body, which is formed with an accommodating space. The purification component is arranged in the accommodating space, and a rolling element is provided at the wall supporting the purification component in the accommodating space.

[0024] In the prior art, when users clean the purification component, they need to remove the purification component from the air purifier. The general disassembly method is to pull it out directly. When pulling it out, the purification component directly slides and rubs against the parts supporting the purification component. As explained in the background technology, the purification component is heavy, which ultimately leads to large pulling resistance and laborious disassembly and assembly. In the present invention, a rolling part is provided at the wall supporting the purification component to convert sliding friction into rolling friction, thereby reducing the friction coefficient, reducing the pulling resistance when pulling the purification component, and facilitating the disassembly and assembly of the purification component.

[0025] 2. In the purification component disassembly and assembly structure of the present invention, an opening is provided at one side of the frame corresponding to the accommodating space. The purification component can be pushed and pulled in the accommodating space through the opening, which restricts the purification component to be pulled out from the side end face of the frame, similar to the setting method of a drawer. Compared with the upward pulling method, this method is more labor-saving and is also conducive to the setting of the rolling part. For example, the rolling part can be set on the bottom end face or the side end face of the frame, reducing the difficulty of design.

[0026] 3. In the purification component disassembly and assembly structure of the present invention, a mounting portion is provided on the frame, and a rolling member is provided on the mounting portion, with its rolling end abutting against the purification component. The rolling member is installed on the frame, which can avoid the increase in the weight of the purification component caused by the installation of the rolling member, and reduce the weight of the purification component for the user as much as possible during the cleaning process.

[0027] 4. The rolling element in the purification assembly disassembly and assembly structure of the present invention is a ball bearing, which is easy to install and has low cost.

[0028] 5. In the purification assembly assembly and disassembly structure of the present invention, the multiple mounting portions are evenly spaced on the bottom end surface along the movement direction of the purification assembly. The purpose of this even arrangement is to ensure that the supporting force exerted by each ball on the bottom end surface of the purification assembly is as uniform as possible, thereby avoiding the possibility of concentrated force at a single location on the bottom end surface, which could cause cracking and damage.

[0029] 6. The purification component disassembly and assembly structure of the present invention also includes a guide portion provided on the purification component and the frame, and the guide portion includes a guide rail and / or guide groove provided on the bottom end surface, and a corresponding guide groove and / or guide rail provided on the purification component, and the guide groove is adapted to the guide rail. Because the purification component is placed inside the accommodating space, in order to ensure the compactness of the overall air purifier structure, the distance between the purification component and the interior of the accommodating space is small. If the direction deviates during the pulling process, it may easily get stuck on the side wall of the accommodating space, making it difficult to disassemble and assemble. The provision of the guide portion ensures the consistency of the movement direction of the purification component during the pulling process, which can prevent the occurrence of the above-mentioned problems.

[0030] 7. The purification assembly assembly and disassembly structure of the present invention also includes a snap-fitting portion provided on the purification assembly and the frame, the snap-fitting portion comprising a buckle and / or a slot provided on the bottom end surface, and a corresponding slot and / or buckle provided on the purification assembly. Due to the provision of the rolling element in the present invention, the purification assembly requires a corresponding retaining structure after reaching the preset installation position to prevent it from rocking within the accommodation space when subjected to external forces due to its low friction resistance.

[0049] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1

[0051] like Figures 1 to 4 As shown, a purification component disassembly and assembly structure provided by this embodiment includes a frame 1, the frame 1 is formed with an accommodating space 11, the purification component 2 is arranged in the accommodating space 11, and a rolling member 3 is provided on the wall supporting the purification component 2 in the accommodating space 11.

[0052] The purification component disassembly structure of this embodiment is used in an electrostatic air purifier. The structure of the purification component of the electrostatic air purifier is as follows: Figure 1 The specific composition is described in the background technology.

[0053] It should be explained that the purification components 2 in this embodiment are provided in two groups in order to improve the purification efficiency of the air. Figure 1 As shown in FIG, two groups of purification components 2 are installed side by side at the bottom end of the air purifier.

[0054] like Figure 2 As shown in FIG, the rolling member 3 in this embodiment is mounted on the bottom end surface 13 of the frame 1 so that the rolling member 3 can better bear the weight of the entire purification component 2.

[0055] In some other embodiments, the rolling element 3 may also be installed on the inner side wall of the frame 1 in the accommodating space 11 , which has the same technical effect.

[0056] In some other embodiments, the rolling element 3 may also be installed simultaneously on the inner side wall of the frame 1 in the accommodating space 11 and on the bottom end surface 13 .

[0057] In some other embodiments, the rolling element 3 may also be directly mounted on the purification component 2 to provide support for the purification component 2 .

[0058] In combination with the prior art, when the user cleans the purification component 2, the purification component 2 needs to be removed from the air purifier. The general disassembly method is to pull it out directly. When pulling it out, the purification component 2 directly slides and rubs against the components supporting the purification component 2. As described in the background technology, the weight of the purification component 2 is large, which ultimately leads to large pulling resistance and laborious disassembly and assembly. In this embodiment, a rolling member 3 is provided at the wall supporting the purification component 2 to convert sliding friction into rolling friction, thereby reducing the friction coefficient, reducing the pulling resistance when pulling the purification component 2, and facilitating the disassembly and assembly of the purification component 2.

[0059] Furthermore, an opening is processed at one side of the frame 1 corresponding to the accommodating space 11, and the size of the opening is slightly larger than the sum of the sizes of the two purification components 2 to ensure that the purification component 2 can be pushed and pulled in the accommodating space 11 through the opening, and the setting of the opening constrains the purification component 2 to be pulled out from the side end face of the frame 1, similar to the setting method of a drawer. Compared with the upward pulling method, this method is more labor-saving and is also conducive to the setting of the rolling member 3. For example, the rolling member 3 can be set on the bottom end face 13 or the side end face of the frame to reduce the difficulty of design.

[0060] The rolling element 3 and its installation method are described below:

[0061] The rolling element 3 in this embodiment is a ball, which is easy and convenient to install with low cost.

[0062] like Figure 2 As shown, a mounting portion 12 is formed on the frame 1 , and the rolling element 3 is mounted on the mounting portion 12 , with its rolling end abutting against the purification component 2 .

[0063] Furthermore, the plurality of mounting portions 12 are evenly distributed on the bottom end surface 13 along the movement direction of the purification component 2. The purpose of the even distribution is to ensure that the supporting force exerted by each ball on the bottom end surface 13 of the purification component is as uniform as possible, thereby avoiding the situation where a single position of the bottom end surface 13 is subjected to concentrated force and thus causes cracking and damage.

[0064] Figure 2 The specific structure of the mounting portion 12 is shown in the figure. The mounting portion 12 includes a groove 121 formed on the frame 1. Part of the ball is accommodated in the groove 121. The shape and size of the groove 121 are adapted to the shape and size of the ball. The definition of adaptation in this embodiment is that the size of the groove 121 is slightly larger than the size of the ball. When the ball is partially accommodated in the groove 121, it can ensure that the ball can rotate freely in the groove 121 without generating large shaking. Large shaking is prone to generating collision noise.

[0065] The mounting portion 12 also includes a clamping arm 122 formed relatively at the notch of the groove 121. The clamping arm 122 is clamped on the ball. In this embodiment, the heads of the two clamping arms 122 are clamped on the side of the middle of the ball away from the groove 121 to ensure that the top end of the ball abuts against the purification component 2.

[0066] Because the purification component 2 is placed inside the accommodating space 11, in order to ensure the compactness of the overall air purifier structure, the distance between the purification component 2 and the inside of the accommodating space 11 is small. If the direction deviates during the pulling process, it is easy to cause it to get stuck at the side wall of the accommodating space 11, making it difficult to disassemble and assemble. Figure 3 and 4 The embodiment shown also includes a guide portion formed on the purification component 2 and the frame 1. The setting of the guide portion ensures the consistency of the movement direction of the purification component 2 during the pulling process, which can prevent the occurrence of the above-mentioned problems.

[0067] The guide portion in this embodiment includes a guide rail 4 provided on the bottom end surface 13 and a corresponding guide groove 5 formed on the purification component 2. The guide groove 5 is specifically formed on the lower end surface of the purification component 2 and the guide groove 5 is adapted to the guide rail 4. Figure 4 As shown in FIG, the cross-sectional shape along the length direction of the guide rail 4 is trapezoidal, and the guide rail 4 is formed between two adjacent rows of rolling elements 3 and the two rows of rolling elements 3 are symmetrically arranged relative to the guide rail 4.

[0068] In some other embodiments, the guide groove 5 may be formed on the bottom end surface 13 , and the guide rail 4 may be formed on the purification component 2 .

[0069] Due to the arrangement of the rolling element 3, the purification assembly 2 requires a corresponding limiting structure after reaching the preset installation position to prevent it from shaking within the accommodating space 11 when subjected to external force due to low friction resistance. Therefore, this embodiment also includes a clamping portion provided on the purification assembly 2 and the frame 1.

[0070] like Figure 2 and 3 As shown, the snap-fitting portion includes a buckle 6 arranged on the bottom end surface 13, the buckle 6 is a tongue protruding from the bottom end surface 13, and a corresponding slot 7 arranged on the purification component 2. When the purification component 2 is pushed into the accommodating space 11, the protruding tongue is first flattened. At the pre-installed position, the tongue pops up and is snapped into the slot 7, completing the positioning and installation of the purification component 2.

[0071] The slot wall of the card slot 7 along the forward direction of the purification component 2 is constructed as an inclined structure, so that the buckle 6 can be more easily disengaged from the card slot 7 when the purification component 2 needs to be pulled out.

[0072] In some other embodiments, the buckle 6 can also be formed on the purification component 2, and the slot 7 can be formed on the bottom end surface 13, which can also achieve the limiting and fixing of the purification component 2.

[0073] Example 2

[0074] This embodiment provides an air purifier, specifically an electrostatic air purifier, which includes the purification component disassembly structure in the above embodiment 1. It has all the technical advantages, which will not be elaborated here one by one.

[0075] When the purification component 2 in this embodiment is in the preset installation position, a handle 8 is installed on the end face close to the opening. The handle 8 in this embodiment is directly formed on the end face of the purification component 2. When the operator needs to disassemble and assemble the purification component 2, the handle 8 acts on the purification component 2, which facilitates the operation.

[0076] This embodiment further includes a cover plate 9, which is detachably arranged at the opening to cover the opening. Pins are formed below the cover plate 9, and a slot is formed on the frame 1. When the cover plate 9 is installed, the pins are first inserted into the slot, and then the cover plate 9 is screwed to the upper end thereof to lock the cover plate 9 to the frame 1.

[0077] During the actual cleaning process of the purification assembly 2, the cover plate 9 is first removed, and then the handle 8 is grasped and the purification assembly 2 is pulled out of the accommodating space 11 with the help of the rolling member 3. When the cleaning is completed, the purification assembly 2 is first pushed into the accommodating space 11 using the guide portion and the rolling member 3, and the installation is judged to be in place by the engagement of the engaging portion, such as the sound of the buckle 6 engaging the engaging groove 7. After the purification assembly 2 is in place, the cover plate 9 is installed, thereby completing the entire cleaning process of the purification assembly 2.

[0078] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
