Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Figures 1-4 This is a schematic diagram of a high-efficiency energy-saving purification device for cleanrooms, provided as an embodiment of this application. This application provides a high-efficiency energy-saving purification device for cleanrooms, comprising:

[0027] Box 100, with an opening on one side surface;

[0028] The door 200 has a sliding rod 101 slidably provided on the edge of the opening. The door 200 is rotatably connected to the sliding rod 101. The door 200 is connected to a nut 211, which is screwed onto the sliding rod 101. The sliding rod 101 is provided with threads. When the door 200 rotates, the nut 211 drives the sliding rod 101 to slide axially.

[0029] The filter cotton is installed in the housing 100. A stop 102 is provided on the slide rod 101 at a position corresponding to the filter cotton. When the stop 102 slides with the slide rod 101, it disengages from limiting the filter cotton.

[0030] For example, the housing 100 is a hollow cubic structure. An air inlet pipe 110 and an air outlet pipe 120 are respectively provided on the outer sides of the opposite ends of the housing 100. The air inlet pipe 110 is connected to the pre-processing equipment to input the air to be processed into the housing 100, and the air processed by the device in this embodiment will be discharged from the air outlet pipe 120.

[0031] In the embodiments of this application, a fan 500 is installed inside the housing 100 near the exhaust pipe 120. The fan 500 is located at the lower air outlet of the filter cotton, thus minimizing dust contact and effectively ensuring its cleanliness, thereby improving its service life and stability. When the fan 500 is powered on, it exhausts air from inside the housing 100 through the exhaust pipe 120, creating a negative pressure inside the housing 100, and ultimately drawing in the air to be treated through the intake pipe 110.

[0032] Furthermore, the door 200 has a sealing strip on its edge facing the body 100. When the door 200 is closed, the sealing strip can fill the gap between the door 200 and the body 100, improving the sealing performance of the body 100. Moreover, after the door 200 is closed, it can be further securely connected to the body 100 by bolts.

[0033] The filter cotton has a multi-layered composite structure, with a border along its edge to maintain its shape. The inner side of the housing 100 has a groove for inserting the filter cotton; the border of the filter cotton is inserted into the groove, allowing the filter cotton to be easily inserted or removed from the opening.

[0034] In one possible embodiment, the door 200 is provided with a sliding hole 201, one end of the connecting rod 212 is connected to the nut 211, and the other end passes through the sliding hole 201 and is connected to the handle 210. The sliding rod 101 is provided with a thread near the center, and the other parts of the sliding rod 101 are smooth. The nut 211 is slidably sleeved in the smooth area of ​​the sliding rod 101. The handle 210 slides and drives the nut 211 to approach the thread. During the rotation of the door 200, the nut 211 is screwed into the thread.

[0035] For example, since the door 200 is not always opened for replacing the filter cotton, but may also be for inspecting the fan or cleaning dust from the housing 100, this application provides a sliding handle 210. The handle 210 serves two purposes: facilitating opening the door 200 and switching modes. If the filter cotton does not need to be removed, the handle 210 can be grasped and rotated upwards. In this case, the slide bar 101 will not be triggered, and the filter cotton remains locked. When the filter cotton needs to be removed, the handle 210 is grasped and slid horizontally first, causing the nut 211 to engage with the thread. Then, the door 200 is rotated upwards. As the door 200 rotates, the nut 211 will be screwed into the thread. Since the slide bar 101 is restricted from rotating axially, it can only slide horizontally. At this point, the stop 102 will move away from its original position blocking the filter cotton, thus releasing the filter cotton from its restraint.

[0036] Furthermore, the slide bar 101 has a rectangular or triangular cross-section at the position where it slides in contact with the housing 100, so the slide bar 101 will not rotate around the axial direction on the housing 100.

[0037] Furthermore, a slider 213 is connected to the end of the connecting rod 212. The slider 213 is slidably disposed in the sliding hole 201, and the end of the slider 213 is connected to the handle 210.

[0038] The sliding hole 201 is elongated, and when the slider 213 slides to the edge of the sliding hole 201, the nut 211 also just abuts against the thread. Therefore, the user only needs to slide the handle 210 to the edge. After the slider 101 slides, the pulling force applied to the nut 211 will act on the edge of the sliding hole 201, and the user does not need to exert continuous force.

[0039] Furthermore, in order to reduce the possibility of dust leakage from the housing 100 through the sliding hole 201, the contact point between the handle 210 and the housing door 200 can be set to be longer than the sliding hole 201, and a sealing gasket can also be set at the contact point between the handle 210 and the housing door 200, so that the handle 210 can not only cover the entire sliding hole 201, but also fill the gap between the handle 210 and the housing door 200.

[0040] In one possible embodiment, the filter cotton includes a first filter cotton 300 and a second filter cotton 400, which are arranged along the length of the housing 100.

[0041] For example, the first filter cotton 300 and the second filter cotton 400 form two barriers for filtering dust, improving the filtration rate of dust in the air. Moreover, the first filter cotton 300 and the second filter cotton 400 can have different pore sizes. Specifically, the first filter cotton 300 is closer to the air inlet pipe 110, while the second filter cotton 400 is closer to the air outlet pipe 120. Therefore, the first filter cotton 300 can have a larger pore size than the second filter cotton 400, achieving a stepped filtration effect.

[0042] In the embodiments of this application, an ultraviolet germicidal lamp 600 is provided on the inner side of the housing 100 between the first filter cotton 300 and the second filter cotton 400. The ultraviolet germicidal lamp 600 can be arranged on multiple inner sides between the first filter cotton 300 and the second filter cotton 400 to achieve a comprehensive sterilization effect.

[0043] After setting two filter cottons, two stops 102 are set on the slide bar 101, and the two stops 102 correspond to the positions of the first filter cotton 300 and the second filter cotton 400 respectively.

[0044] In one possible embodiment, a spring is connected between the end of the slide rod 101 and the housing 100, and the spring is stretched when the slide rod 101 slides under the action of the nut 211.

[0045] For example, the spring is preferably located inside the housing 100. After the filter cotton is replaced, the door 200 will be closed, at which point the nut 211 will disengage from the thread, and the slide rod 101 will be pulled back to its initial position by the spring force, so as to facilitate the next opening of the door 200.

[0046] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0047] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
