[0002] In hospitals, biological or medical research institutions, it is often necessary to provide clean air to the space to improve the quality of treatment or products.

[0003] Generally speaking, the volume of air supply units is relatively large. In order to improve the aesthetics, most clean rooms and other spaces integrate air supply units into the suspended ceiling. However, the internal structure of the suspended ceiling is relatively complex, and installing the air supply unit inside the suspended ceiling necessarily requires relatively complex devices, which makes the installation and removal of the air supply unit relatively cumbersome. Summary of the invention

[0004] The embodiment of the present invention provides an airflow device for a medical space air supply unit, which is used to solve the problem in the prior art that the installation and disassembly of the air supply unit when it is installed inside a suspended ceiling are relatively complicated.

[0005] On the one hand, an embodiment of the present invention provides a medical space air supply unit airflow device, including a filter unit and an air supply unit, the filter unit and the air supply unit are respectively connected to a suspension rod, and the suspension rod is used to be fixed inside the ceiling of the medical space;

[0006] The filter unit and the air supply unit are both provided with locking components, which include:

[0007] A driving rod is rotatably arranged inside the filter unit and the air supply unit, and a driving wheel and a locking wheel are arranged on the driving rod;

[0008] A driven wheel is rotatably arranged inside the filter unit and the air supply unit, a movable wheel is rotatably arranged on the suspension rod, the driven wheel is screwed to the lower part of the suspension rod, and the driven wheel rotates under the drive of the locking wheel, so that the suspension rod extends into the filter unit or the air supply unit;

[0009] When the movable wheel moves to a position corresponding to the driving wheel along with the suspension rod, the driving rod drives the driving wheel to rotate, pushing the movable wheel away from the driving rod, so that the filter unit or the air supply unit moves in a direction close to each other.

[0010] The medical space air supply unit air flow device of the present invention has the following advantages:

[0011] The filter unit or the air supply unit can be moved vertically and horizontally by operating the driving rod only, which not only can conveniently fix the filter unit and the air supply unit in the ceiling, but also can tightly connect the filter unit and the air supply unit together, simplifying the disassembly and assembly operations inside the ceiling.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Figure 1-7A schematic diagram of the structure of a medical space air supply unit airflow device provided in an embodiment of the present invention. The embodiment of the present invention provides a medical space air supply unit airflow device, the device comprising a filter unit 100 and an air supply unit 200, the filter unit 100 and the air supply unit 200 are respectively connected to a suspension rod 300, and the suspension rod 300 is used to be fixed inside the ceiling of the medical space;

[0023] The filter unit 100 and the air supply unit 200 are both provided with locking components, and the locking components include:

[0024] A driving rod 130 is rotatably disposed inside the filter unit 100 and the air supply unit 200, and a driving wheel 131 and a locking wheel 132 are disposed on the driving rod 130;

[0025] The driven wheel 103 is rotatably arranged inside the filter unit 100 and the air supply unit 200. The movable wheel 310 is rotatably arranged on the suspension rod 300. The driven wheel 103 is screwed to the lower part of the suspension rod 300. The driven wheel 103 rotates under the drive of the locking wheel 132, so that the suspension rod 300 extends into the filter unit 100 or the air supply unit 200.

[0026] When the movable wheel 310 moves to a position corresponding to the driving wheel 131 along with the suspension rod 300, the driving rod 130 drives the driving wheel 131 to rotate, pushing the movable wheel 310 away from the driving rod 130, so that the filter unit 100 or the air supply unit 200 moves toward each other.

[0027] Exemplarily, a primary filter, a high-efficiency filter and other filtering devices can be arranged inside the filter unit 100 to filter and purify the air, and a fan can be arranged inside the air supply unit 200. By connecting the air supply unit 200 to the air outlet of the filter unit 100, the air supply unit 200 can provide negative pressure to the filter unit 100, so that the filter unit 100 can inhale the air and filter it.

[0028] The driving wheel 131, locking wheel 132, driven wheel 103 and movable wheel 310 in the locking assembly can all use smooth wheels or gears. If smooth wheels are used, an anti-skid layer needs to be provided on their surfaces to increase the friction during contact and avoid slipping.

[0029] In a possible embodiment, a hanging hole 101 is opened on the top surface of the filter unit 100 and the air supply unit 200 , and the hanging rod 300 passes through the hanging hole 101 and is inserted into the driven wheel 103 .

[0030] Exemplarily, a plurality of lifting holes 101 can be provided on the top surface of the filter unit 100 and the air supply unit 200. For example, a lifting hole 101 can be provided at each of the four corners of the top surface of the filter unit 100 and the air supply unit 200. The lifting hole 101 can be a blind hole or a through hole.

[0031] In the embodiment of the present invention, when a plurality of hanging holes 101 are provided on the filter unit 100 and the air supply unit 200, a locking assembly may be provided at a position corresponding to at least one hanging hole 101 inside the filter unit 100 or the air supply unit 200, and only a driven wheel 103 may be provided at a position corresponding to other hanging holes 101 inside the filter unit 100 or the air supply unit 200 to be screwed on the hanging rod 300. Moreover, the hanging rod 300 inserted into other hanging holes 101 does not need to be provided with a movable wheel 310.

[0032] In a possible embodiment, a slide groove is provided on the bottom surface of the lifting hole 101 , and the driven wheel 103 is slidably disposed in the slide groove, and the driven wheel 103 rotates in the slide groove.

[0033] Exemplarily, since the push wheel 131 will move the suspension rod 300 inside the suspension hole 101 during the process of pushing the movable wheel 310, the driven wheel 103 will also move with the suspension rod 300. By setting a slide groove, the present invention can make the driven wheel 103 rotate under the drive of the locking wheel 132, and can also move relative to the suspension hole 101 under the drive of the suspension rod 300. However, since the suspension rod 300 is fixed inside the ceiling, when the push wheel 131 pushes the suspension rod 300 away from the driving rod 130, it is actually the filter unit 100 or the air supply unit 200 that is moving, and whether the filter unit 100 or the air supply unit 200 is installed, both move in a direction close to each other so that the two can be close together. Moreover, when the filter unit 100 or the air supply unit 200 is stably installed on the suspension rod 300, the two are also just close together, so that air can flow between the two.

[0034] In a possible embodiment, an operation hole 102 is opened on the bottom surface of the filter unit 100 and the air supply unit 200 , and the lower end of the driving rod 130 extends out of the operation hole 102 .

[0035] Exemplarily, the driving rod 130 has an operating head 133 at one end of the operating hole 102. The operating head 133 can be provided with a straight or cross operating opening, or a hexagonal or hexagonal shape, and the operator can rotate the driving rod 130 using a matching tool, such as a screwdriver or a wrench.

[0036] In a possible embodiment, the driving wheel 131 is an eccentric wheel.

[0037] For example, the driving wheel 131 may be a wheel-shaped structure with a circular, elliptical or spiral cross section. When a circular driving wheel 131 is used, it may be installed on the driving rod 130 in a non-coaxial manner. When an elliptical or spiral driving wheel 131 is used, it may be installed on the driving rod 130 in a coaxial or non-coaxial manner.

[0038] In a possible embodiment, a sealing assembly 120 is provided at a side edge of the filter unit 100 facing the air supply unit 200 .

[0039] Exemplarily, the sealing assembly 120 may be a rubber ring. When the filter unit 100 and the air supply unit 200 are tightly pressed together, the sealing assembly 120 may fill the gap between the two, so that all the air flowing out of the filter unit 100 flows into the air supply unit 200 without leaking from the gap between the two.

[0040] In a possible embodiment, an air inlet duct 110 is provided at the air inlet of the filter unit 100 .

[0041] Exemplarily, the air inlet pipe 110 may be disposed on the filter unit 100 in a detachable or fixed manner, and a terminal end of the air inlet pipe 110 may be connected to an air source to provide a continuous supply of air to the filter unit 100 .

[0042] Furthermore, the air outlet of the air supply unit 200 is provided with an air supply pipe 210. Since the air supply unit 200 is arranged inside the ceiling, the air outlet of the air supply unit 200 is preferably arranged at its bottom, and accordingly, the air supply pipe 210 is also arranged at the bottom of the air supply unit 200.

[0043] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
