Description

Technical Field

[0001] This utility model belongs to the field of ventilation technology, and in particular relates to a non-powered, low-noise ventilation and purification device. Background Technology

[0002] Non-powered ventilation and purification devices are ventilation and air exchange equipment installed throughout the wall. They provide sufficient fresh outdoor air 24 hours a day without electricity, promoting indoor and outdoor air convection. The filter plates in the wall-penetrating pipes can filter and purify the incoming air, improving the indoor environment and protecting the health of the people inside. In addition, some non-powered low-noise ventilation and purification devices have sound-absorbing cotton plates installed in the pipe walls to reduce the noise of the incoming air, achieving a low-noise operation effect and further optimizing the comfort of using the ventilation device.

[0003] When installing a non-powered, low-noise ventilation and purification device, the through-wall pipe needs to be placed in a hole in the wall. There will be a gap between the wall hole and the through-wall pipe. After the pipe is installed, silicone foam is used to fill and seal the gap. However, the bonding stability of the foam will decrease after long-term use. Therefore, a non-powered, low-noise ventilation and purification device is needed. This device can use a clamp on the surface of the through-wall pipe to provide inward support to the inner wall of the wall hole, thereby ensuring a stable connection between the through-wall pipe and the wall hole, and improving the stability of the ventilation device in the wall hole installation position. Utility Model Content

[0004] The purpose of this utility model is to provide a non-powered, low-noise ventilation and purification device. By using a clamp on the surface of the through-wall pipe to provide inward support to the inner wall of the wall hole, the through-wall pipe and the wall hole can be stably connected, thereby improving the stability of the ventilation device in the wall hole and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A non-powered, low-noise ventilation and purification device, comprising a wall-penetrating pipe: a rain cover and a guard plate are fixedly connected to the end of the wall-penetrating pipe; a purification filter plate and a sound-absorbing cotton plate are fixedly connected to the inner wall of the wall-penetrating pipe; an elastic switch is installed on the inner wall of the wall-penetrating pipe; a sealing cover plate is installed on the surface of the elastic switch; a perforated plate is slidably connected to the surface of the wall-penetrating pipe and an internal threaded ring is threadedly connected thereto; a wedge-shaped slide rail is fixedly connected to the surface of the wall-penetrating pipe; a wedge-shaped slider is slidably connected to the surface of the wedge-shaped slide rail; a connecting block is fixedly connected to the surface of the wedge-shaped slider by bolts; a pull rod and a connecting support block are provided on the outer side of the wall-penetrating pipe; and a clamping plate is fixedly connected to the surface of the connecting block.

[0006] Preferably, the perforated plate and the internal threaded ring are rotatably connected.

[0007] Preferably, the pull rod and the wedge-shaped slider are fixedly connected by bolts, and both the wedge-shaped slider and the orifice plate are rotatably connected to the connecting support block by a rotating shaft.

[0008] Preferably, the clamping plate is a stainless steel arc-shaped plate.

[0009] Preferably, the right end of the rain cover is bent and tilted to the lower right.

[0010] Preferably, the surface of the through-wall pipe is provided with a threaded surface that is compatible with the internal threaded ring.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses an internal threaded ring to drive the orifice plate to move outside the wall-penetrating pipe, so that the orifice plate pulls the tie rod through the connecting support block. At this time, under the guidance of the wedge-shaped slide rail, the tie rod drives the connecting block to move to the outside of the wall-penetrating pipe through the wedge-shaped slider. Then, the connecting block drives the clamping plate to support and compress the inner wall of the wall hole. This achieves the purpose of inward support of the inner wall of the wall hole by the clamping plate equipped on the surface of the wall-penetrating pipe, so that the wall-penetrating pipe and the wall hole can be stably connected, thereby improving the stability of the ventilation device in the wall hole installation position.

[0013] 2. By setting the arc plate of the clamping plate, this utility model increases the contact area between the clamping plate and the inner wall of the wall hole, thereby improving the stability of the connection between the clamping plate and the wall hole, and thus improving the stability of the device's position when installed in the wall.

[0020] In the following description, embodiments of the non-powered, low-noise ventilation and purification device of this invention will be described with reference to the accompanying drawings.

[0023] Example 2:

[0024] Figure 1-3 This invention illustrates a non-powered, low-noise ventilation and purification device according to an embodiment of the present invention. It includes a through-wall pipe 1: a rain cover 2 and a guard plate 3 are fixedly connected to the end of the through-wall pipe 1; a purification filter plate 4 and a sound-absorbing cotton plate 5 are fixedly connected to the inner wall of the through-wall pipe 1; an elastic switch 6 is installed on the inner wall of the through-wall pipe 1; a sealing cover plate 7 is installed on the surface of the elastic switch 6; a perforated plate 8 is slidably connected to the surface of the through-wall pipe 1 and threaded with an internal threaded ring 9; a wedge-shaped slide rail 10 is fixedly connected to the surface of the through-wall pipe 1; a wedge-shaped slider 11 is slidably connected to the surface of the wedge-shaped slide rail 10; and the wedge-shaped slider 11... The surface of the through-wall pipe 1 is fixedly connected to the connecting block 12 by bolts. The outside of the through-wall pipe 1 is provided with a tie rod 13 and a connecting support block 14. The surface of the connecting block 12 is fixedly connected to a clamping plate 15. The clamping plate 15 is a stainless steel arc plate. The arc plate of the clamping plate 15 increases the contact area between the clamping plate 15 and the inner wall of the wall hole, thereby improving the stability of the connection between the clamping plate 15 and the wall hole, thus improving the stability of the device's position in the wall. The right end of the rain cover 2 is bent and tilted to the lower right. The surface of the through-wall pipe 1 is provided with a threaded surface that matches the internal threaded ring 9.

[0025] Working Principle: When using this utility model, the user places the through-wall pipe 1 into the wall hole, then rotates the internal threaded ring 9 to move the orifice plate 8 outside the through-wall pipe 1. This causes the orifice plate 8 to pull the pull rod 13 via the connecting support block 14. Guided by the wedge-shaped slide rail 10, the pull rod 13 moves the connecting block 12 to the outside of the through-wall pipe 1 via the wedge-shaped slider 11. This causes the connecting block 12 to move the clamping plate 15 to support and compress the inner wall of the wall hole. Then, silicone foam sealant is used to seal the space between the through-wall pipe 1, the clamping plate 15, and the inner wall of the wall hole. When the device presses the sealing cover plate 7... The elastic switch 6 opens under the action of its elasticity and disengages from the through-wall pipe 1, allowing the through-wall pipe 1 to circulate with the outside. Outside air enters the through-wall pipe 1 through the baffle 3. The rain cover 2 and the baffle 3 work together to protect the incoming air from rain, insects, and birds. Then, the air enters the room after being purified, filtered, and noise-reduced by the purification filter plate 4 and the sound-absorbing cotton plate 5. The clamps on the surface of the through-wall pipe provide inward support to the inner wall of the wall hole, thus ensuring a stable connection between the through-wall pipe and the wall hole, thereby improving the stability of the ventilation device in the wall hole.

[0026] In summary, this non-powered, low-noise ventilation and purification device moves the orifice plate 8 outside the wall-penetrating pipe 1 via the internal threaded ring 9. This causes the orifice plate 8 to pull the pull rod 13 via the connecting support block 14. Guided by the wedge-shaped slide rail 10, the pull rod 13 moves the connecting block 12 to the outside of the wall-penetrating pipe 1 via the wedge-shaped slider 11. Subsequently, the connecting block 12 drives the clamping plate 15 to support and compress the inner wall of the wall hole. This achieves the goal of providing inward support to the inner wall of the wall hole through the clamping plate on the surface of the wall-penetrating pipe, thereby ensuring a stable connection between the wall-penetrating pipe and the wall hole, and improving the stability of the ventilation device's installation position in the wall hole.
