After the high and low voltage electrostatic module is used for a period of time, it needs to be removed for cleaning. The installation method of the electrostatic module in the existing high and low voltage electrostatic range hood is usually to install a base in the range hood in advance, and then insert the electrostatic module into the range hood along the base. When cleaning the inside of the range hood, the base will cause certain obstacles, resulting in inconvenience in maintaining the range hood. Summary of the Utility Model

Specific implementation manner

[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0023] See Figures 1-5 , in this embodiment, the high and low voltage electrostatic purification module and its installation structure include the main body 1 of the electrostatic module and the fixing mechanism 2. Two groups of the fixing mechanisms 2 are provided and are respectively arranged on the front and rear sides of the main body 1. The fixing mechanism 2 can extend longitudinally out of the main body 1 and abut against the inner walls on the upper and lower sides of the range hood housing 3.

[0024] When the present utility model is installed and used, first insert the main body 1 of the electrostatic module into the range hood housing 3, and then drive the fixing mechanism 2 to extend out of the outside of the main body 1 and make the fixing mechanism 2 abut against the inner wall of the range hood, so that the main body 1 can be fixed in the range hood housing 3 through the fixing mechanism 2. Therefore, through the structure of the present utility model, the purpose of fixing the main body 1 of the electrostatic module can be achieved without installing a base in the range hood housing 3, thereby reducing the difficulty of cleaning the oil stains in the range hood housing 3 and improving the cleaning efficiency of the range hood.

[0025] At the same time, the main body 1 of the electrostatic module in the present utility model can adjust its left and right positions in the range hood housing 3 and be fixed through the fixing mechanism 2. Compared with the existing method using a base, the present utility model can more conveniently adjust the left and right positions of the main body 1 according to the structural layout in the range hood housing 3, so as to adapt to different installation and use requirements, and enable the present utility model to meet different use scenarios within a certain range.

[0026] See Figure 2 、Figure 3 The fixed mechanism 2 includes a rotating member 21, a transmission member 22, and a movable member 23. The cross-section of the rotating member 21 is elliptical, and the rotating member 21 is rotatably arranged relative to the main body 1. There are two transmission members 22, which are respectively arranged on the upper and lower sides of the rotating member 21 in a vertically sliding manner. The inner ends of the transmission members 22 abut against the arc surface of the rotating member 21, and the movable member 23 is fixed on the transmission members 22 and is located on the upper and lower sides of the main body 1.

[0027] According to the shape characteristics of the ellipse, when the rotating member 21 is driven to rotate, the inner ends of the transmission members 22 abutting against the rotating member 21 can be pushed outwards by the rotating member 21, so as to drive the transmission members 22 to slide outwards relative to the main body 1. Furthermore, the movable member 23 fixed on the outer ends of the transmission members 22 can extend outwards relative to the main body 1 and finally make the movable member 23 abut against the inner wall of the range hood housing 3 to achieve fixation. When the rotating member 21 is driven to rotate and reset, the transmission members 22 contract towards the main body 1, causing the separation between the movable member 23 and the inner wall of the range hood housing 3, so that the fixing effect on the main body 1 disappears. At this time, the main body 1 can be taken out of the range hood housing 3 for cleaning, which is convenient for use.

[0028] See Figure 1 、 Figure 2 Cover plates 4 are fixed on the front and rear sides of the main body 1 by bolts. The two fixed mechanisms 2 are respectively arranged on the front and rear cover plates 4. The rotating member 21 is rotatably arranged inside the cover plate 4, and the transmission member 22 is slidably arranged inside the cover plate 4.

[0029] By arranging the fixed mechanism 2 on the cover plate 4, and the cover plate 4 is detachably installed on the main body 1 by bolts. When the main body 1 needs to be cleaned, the cover plates 4 on the front and rear sides of the main body 1 together with the fixed mechanism 2 can be removed, exposing the front and rear sides of the electrode plates inside the main body 1, so as to facilitate the cleaning of the inside of the main body 1.

[0030] See Figure 2 、 Figure 3 The transmission member 22 includes two transmission rods 24. The two transmission rods 24 are symmetrically arranged left and right with respect to the rotation center of the rotating member 21. A first spring 25 is arranged between the transmission rod 24 and the cover body, and the first spring 25 drives the transmission rod 24 to contract towards the cover plate 4.

[0031] Under the action of the first spring 25, the inner end of the transmission rod 24 is always in contact with the rotating member 21. The two transmission members 22 on the upper and lower sides of the rotating member 21, including four transmission rods 24, can clamp the rotating member 21, so that when the rotating member 21 rotates to the vertical state and pushes the transmission member 22 outwards, causing the movable member 23 to abut against the inner wall of the range hood housing 3, it can maintain this state under the action of the transmission rod 24, thereby reducing the risk of loosening between the movable member 23 and the range hood housing 3 due to accidental rotation of the rotating member 21 in this state, improving the stability of the fixing effect of the main body 1. At the same time, when the transmission member 22 is rotated to the horizontal state, under the action of the first spring 25, the transmission member 22 and the movable member 23 can automatically contract towards the inside of the main body 1, reducing the risk of collision between the movable member 23 and the range hood housing 3 when the present utility model is inserted into or removed from the range hood housing 3.

[0032] See Figure 2 , two movable members 23 are provided, and the two movable members 23 are symmetrically fixed on the transmission member 22 with respect to the main body 1 in the left-right direction. Anti-slip pads 26 are provided on the contact surfaces of the movable members 23 with the range hood housing 3.

[0033] Since fixing mechanisms 2 are provided on both the front and rear sides of the main body 1, this structure enables there to be four movable members 23 on both the upper and lower sides of the main body 1, reducing the risk of the main body 1 shaking in the range hood housing 3. At the same time, by providing anti-slip pads 26 on the movable members 23, the risk of the main body 1 slipping left and right in the range hood housing 3 can be reduced, improving the stability when the main body 1 is fixed in the range hood housing 3.

[0034] See Figure 3 , Figure 4 , the rotation axes of the rotating members 21 in the two fixing mechanisms 2 are fixedly connected by a cross bar 5. The two ends of the cross bar 5 are respectively inserted into the two rotating members 21 and cannot rotate.

[0035] Since it is not convenient to drive the rotation of the rotating member 21 located at the rear side of the main body 1 after the main body 1 is inserted into the range hood housing 3, in the present utility model, the front and rear rotating members 21 are connected by the cross bar 5. By driving the rotation of the front rotating member 21, the two rotating members 21 can be driven to rotate simultaneously, improving the convenience of installing and removing the main body 1. The two ends of the cross bar 5 and the hole positions on the rotating member 21 for inserting the cross bar 5 can be adaptively set to a polygonal shape. While ensuring that there is no rotation between the cross bar 5 and the rotating member 21, this plug-in structure also facilitates the connection and separation between the cross bar 5 and the rotating member 21, thereby facilitating the installation of the cover plate 4 and the fixing mechanism 2 onto the main body 1 and the removal from the main body 1.

[0036] See Figure 1 , Figure 2 , Figure 5, a disk 41 is rotatably arranged in the cover plate 4, the disk 41 is coaxially fixed with the rotating member 21, a handle 6 is arranged on the outer side of the disk 41, the handle 6 is slidably inserted into the disk 41 in the front-back direction, and a clamping mechanism 61 which cooperates with each other is arranged between the handle 6 and the disk 41. Two clamping mechanisms 61 are arranged and are respectively close to the inner and outer ends of the handle 6.

[0037] When the main body 1 is installed into the range hood housing 3 or removed from the range hood housing 3, the handle 6 can be pulled outwards and fixed to the disk 41 through the clamping mechanism 61, so that the disk 41 and the rotating member 21 can be easily driven to rotate by the handle 6 and the main body 1 can be moved; when the main body 1 is inserted into the range hood housing 3 and the handle 6 is rotated to make the rotating member 21 rotate so as to drive the movable member 23 to abut against the inside of the range hood housing 3, the handle 6 is pressed to move into the disk 41 and fixed to the rotating member 21 through another clamping mechanism 61, thereby reducing the occupied space of the handle 6 protruding outwards and facilitating the installation of the main body 1.

[0038] See Figure 5 , the clamping mechanism 61 includes a second spring 62 and a steel ball 63. A through hole 64 is formed in the handle 6, the steel ball 63 and the second spring 62 are arranged in the through hole 64, the diameter of the opening at one end of the through hole 64 is smaller than the diameter of the steel ball 63, and a groove 65 which is matched with the steel ball 63 for clamping is arranged in the disk 41.

[0039] When the clamping mechanism 61 is installed, the steel ball 63 and the second spring 62 are sequentially placed into the through hole 64 through the opening on one side of the through hole 64, and then fixed to the through hole 64 through a pin or a screw, so that the steel ball 63 always abuts against the opening on the other side of the through hole 64 under the action of the second spring 62. A part of the steel ball 63 protrudes outwards through the opening on this side and can be clamped into the groove 65 in the disk 41. When the handle 6 is driven to slide back and forth on the disk 41, the steel ball 63 is pressed into the through hole 64, so that the handle 6 can slide back and forth on the disk 41 and is fixed through the clamping mechanism 61, facilitating the extraction and insertion of the handle 6.

Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claim book, they should all belong to the protection scope of the present utility model.
