Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation devices. In particular, it relates to a reversible ventilator assembly for installation on rigid and / or flexible walls. Background Art

[0002] The various applications of ventilators installed on walls or partitions are related to the generation of airflows. For example, ventilating a closed room, controlling indoor cultivation parameters, or removing odors. Depending on the airflow direction related to the installation direction of the device on the corresponding wall, the ventilator discharges or inhales the airflow into the area defined by one or more walls; the utility model can have these two functions, depending on its installation position. For the convenience of explaining this specification and its appended claims, from now on, when the device discharges air from a closed space, we will call the device an "exhaust machine", and when the device acts in the reverse direction, we will call the device an "intake machine"; the term ("intake machine" and derivatives, such as "inhalation") refers to the terms used in indoor or greenhouse cultivation techniques and is selected as the term here, although the utility model is by no means limited to such applications, as will be clearly shown in the following sections.

[0003] Ventilators (exhaust machines) are used to maintain the circulation of indoor air to control parameters such as temperature and humidity, which is very important for the use purposes of organisms (humans, animals, or plants) and the preservation of stored items or materials. Sometimes it is necessary to create larger or smaller airflows according to the room use; another key point is the ability to control the incoming air flow to be greater than the outgoing air flow (or vice versa). Also, the same room, cabinet, compartment, site, or cubicle is used for different purposes in different locations, so it is desirable to be able to change the exhaust / intake mode without complex engineering or operations and while maintaining the same airflow efficiency for each exhaust / intake device.

[0004] In various applications, it is very advantageous to be able to very conveniently adapt the air conversion mode to different scenarios, including for the greenhouse where the above-mentioned indoor plants are located, or for example, in mobile toilets or construction site temporary housing, when the indoor air is not fresh, to have a better exhaust airflow. When replacing the indoor air, mainly an intake airflow is involved. It is also applicable to test rooms or enclosed rooms, for the breeding rooms set up to adjust the air required for these animals, to avoid special enclosed odors and protect items that may be damaged by moisture (for example, by using the timed start of the ventilator / exhaust machine), applicable to the compartments provided in sex shops or individual entertainment and special entertainment venues, and also applicable to walls that generally have at least one rigid and / or flexible wall or partition.

[0005] In view of the above, the present utility model provides a reversible ventilator assembly that can easily switch from the exhaust mode to the intake mode during operation without the need for special design of the motor-driven rotating impeller. Generally, a device designed to operate bidirectionally is not as efficient as a unidirectional operating device. In any case, the present utility model can replace unidirectional operating equipment, is very easy to assemble, has diversity in the configuration of various devices, and is combined with the ordinary passive ventilation fittings described below. Summary of the Utility Model

[0006] To this end, the present utility model provides a reversible ventilator assembly for installation on rigid and / or flexible walls. The device mainly includes a wall support for rigid and / or flexible walls, a reversible ventilator, and a blind cover, the features of which will be described in detail below.

[0007] According to the motor-driven rotating impeller, the ventilator includes an exhaust side and an intake side. Both sides of the ventilator include the same first coupling device for installing the device on either side. The wall support will be installed on a wall or partition (or any similar surface where it is necessary to form an inlet and outlet air flow, which can be a relatively rigid wall such as wood, metal or plastic, or a softer plastic wall such as fabric) that has been pre-drilled for ventilation. The wall support includes fastening means fixed to the wall around the pre-drilled ventilation hole, and one or more second through holes corresponding to the hole positions of the wall ventilation hole. The wall support also includes connectors located on both sides of the ventilator that are coupled to the ventilator.

[0008] Features of the present utility model: The support gasket of the reversible ventilator assembly. The support gasket includes a third through hole that coincides with the ventilation hole position of the above-mentioned support; it also includes fastening means for fixing it to the wall. In addition, the shape of the support gasket should be such that when its third through hole overlaps with one or more second through holes of the wall support, the shape of the support gasket is at least the same as that of the wall support; thus, this combination of shapes provides stronger firmness for the wall support and the blind cover, just like a sandwich with the wall in the middle, especially suitable for cases where the wall is made of relatively softer, weaker, thinner or flexible materials.

[0009] Another feature of the utility model is a complementary second connection device for fixing the support member gasket and the wall support member to the wall. That is, the fixing device can fix the wall support member and the support member gasket to each other or stabilize them together while fixing the support member gasket and the wall support member to the wall respectively. It can be understood that according to this feature of the utility model, these complementary connection fixing devices can be screws and corresponding openings of the support member gasket and the wall support member, and the above-mentioned support member gasket-wall-wall support member fixing is achieved with a single reinforcement. Other parts such as bolts and nuts, strong adhesives, magnets, Velcro, etc. can also be used.

[0010] Another feature of the utility model is a blind cover of a reversible ventilator assembly, which can be used to cover the ventilator as a passive ventilation device or only for closing the first through hole in the wall. The blind cover also includes a first coupling device that is the same as the first coupling device of the above-mentioned exhaust fan, so they are also complementary to the second coupling device of the wall support. The blind cover also includes a fourth through hole that overlaps with part of the first through hole on the wall to allow air to pass through when needed. Similarly, the blind cover also includes a partition that covers another part of the first through hole on the wall. Finally, the blind cover also includes a sealing cover rotatably fixed to the blind cover; the sealing cover includes a vent portion (i.e., an open portion, an opening) and a sealing portion (a covered portion), so that the sealing cover can be rotated so that its sealing portion completely covers the fourth through hole of the blind cover (not allowing air to pass through, no ventilation), or can be rotated so that the vent portion completely overlaps with the fourth through hole of the blind cover (complete ventilation); it can also be rotated to any intermediate position between the above two positions.

[0011] Another feature of the utility model is that the partition of the blind cover comprises a hole or a plurality of holes, and the sealing cover comprises a pivot pin rotatably mounted in the hole. By this particular method, the rotation or pivot pin rotation described in the preceding paragraph is realized.

[0012] Another feature of the utility model is that the pivot pin is rotatably mounted, which may be a split pivot pin with a flared end, the pivot pin being longitudinally split so that it can be compressed when entering the hole, and the flared end prevents it from falling out after insertion; the pivot pin enters the hole after pressing a button, and the flat portion of the flared end faces the partition, and because it has a flange portion, it is more difficult to fall out; the end is provided with a button, press or knob-type insertable cap or any combination thereof, and once the pin end is inserted into the hole, it is embedded in the cap at the end.

[0013] Another feature of the present invention is that the vent portion and the sealing portion of the sealing cover include at least one rib-shaped component or flange components (preferably multiple) to facilitate manual rotation of the sealing cover by grasping or twisting these rib-shaped components.

[0014] Another feature of the present utility model: The first coupling device of the air extractor and the blind cover that complement each other and the second coupling device of the wall support are bayonet type. Specifically, the air extractor and the blind cover or the wall support include alternating circumferential lips, and there is also a circumferential space between them. It is envisaged that after these flanges are coupled together, a circular contour is formed, which opens towards the inside of the circumference; thus, for coupling, the circumference of one component overlaps the circumference of the other component, the circumferential flange of each component is located within the circumferential space of the other component, and the components rotate relative to the ventilator or the blind cover of the wall support until the flange of one component is coupled to the flange of the other component by friction, and it opens towards the outside of the circumference.

[0015] According to another embodiment of the present utility model, the reversible ventilator assembly may include an extension coupling. The extension coupling is in the form of a duct or pipe to allow air to pass through its interior. It is fixed to the wall support through a wall connector, and thus can be the same as or equivalent to the first coupling device for the blind cover or the ventilator described above. At its other end, the extension coupling is adapted or only adapted to couple or fix the corresponding duct, so that the air flow can be directed to the intended position according to the length and structure of the guiding duct.

[0016] Finally, another feature of the present utility model: The first coupling device of the ventilator, the wall support and the blind cover can be a magnet, a Velcro, a protrusion / eminence that can be engaged with the corresponding housing, or internal and external threads.

[0033] In this section, the present utility model will be briefly described with reference to the above-mentioned drawings, and certain details not mentioned above will be emphasized.

[0034] Figure 1A perspective view of the ventilator (300) forming part of the embodiment of the present utility model is shown. The ventilator (300) includes a housing, a protective grille, and common internal components for operating the operation of such a device, and these components are not the object of the present utility model. Based on this, it should be noted that, as is usually the case, the ventilator (300) has a suction side and an exhaust side. As can be seen from the figure, the ventilator (300) further includes a first coupling device (310), and in one preferred embodiment, the first coupling device (310) is in the form of an outwardly opening circumferential flange. These first coupling devices (310) are located on both sides of the ventilator (300), and can be clearly seen from Figure 2 the schematic diagram.

[0035] Figure 3 A wall support (100), a wall (200), and a support gasket (400) are shown. A first through hole (210) has been pre-formed in the wall (200) at a position where air circulation is specifically required to facilitate air circulation to one side or the other side of the wall (200). The wall support (100) includes fastening means (110) for fixing to the wall, and the fastening means depends on the material of the wall support (100), such as screws, and also includes corresponding holes if necessary. The wall support (100) further includes a first coupling device (310) for the ventilator (300) and a complementary second coupling device (130), such that in any case, whether operating as an exhaust machine or an intake machine, it can be fixed to the wall support (100) through one side or the other side. These complementary coupling devices (310, 130) are preferably quick coupling devices to more easily switch the exhaust machine / intake machine (300) function. For example, in a hypothetical case, a user has arranged a plurality of reversible ventilators (300) at different positions on the wall (200) of a cabinet. The device of the present utility model can be used to generate a plurality of airflows to update a specific part of the cabinet through different paths, or only introduce air into the cabinet or only exhaust air from the cabinet. Thus, as will be described in detail later, as in the case of installing the ventilator (300), the present utility model further includes allowing the first through hole (210) on the wall (200) to be quickly closed, or retaining the passive ventilation option.

[0036] If the wall (200) is made of sufficiently strong wood, metal, plastic, or durable polymer, etc., the present utility model only provides the installation of the wall support (100), and at the same time, as an optional item in other embodiments, it is proposed to install a support pad (400) on the other side of the wall (200), facing the wall support (100)( Figure 3 and Figure 4(as shown). The last case is more suitable for the wall (200) of soft materials, such as the cabinet wall (200) made of fabric or similar materials, because the support gasket (400) is regarded as a reinforcement bracket for the self-wall support (100), providing greater stability for the assembly. The above-mentioned reinforcement (110) can be used to fix the wall support (100) and the support gasket (400) together; in this case, screws and corresponding screw holes are required, but other devices can also be used, such as bolts and nuts, strong adhesives, etc. In any case, the support gasket (400) can act as a decorative piece, so it can be used even on a more rigid wall (200). In this case, the wall support (100) alone can already play a role.

[0037] In Figure 3 the illustrated embodiment, the complementary coupling devices (310, 130) have been implemented in a bayonet coupling manner, equipped with a flange member on the wall support (100) and two side flange members on the ventilator (300), in such a way that one side of the wall support (100) and the ventilator (300) are mounted in a relative position on the other side ( Figure 5 (as shown), and the two are close to each other until they are coupled ( Figure 6 (as shown). These coupled flange members are similar in shape to the contour of a circle and are frictionally coupled by a simple rotation of the ventilator (300); and, in addition to the frictional coupling, several flange members are provided in some flange members, as well as certain possible coupling cavities, and are perpendicular to the wall (200), so as to achieve bayonet closing and key supplementary closing coupling through friction. For example, in Figures 1 to 6 these flange members can be seen in more detail, where, in the case of the wall support (100), these flange members open towards the inside of the circumference, and in the case of the wall support (100), they open towards the inside of the circumference formed by them. If it is the ventilator (300), its flange members open outwards along a circumferential contour slightly smaller than the first circumference corresponding to the wall support (100), so that these flange members can be coupled with each other as the ventilator (300) rotates.

[0038] This technical feature of the ventilator (300) quickly coupling the wall support (100) on both sides can be achieved by other complementary coupling devices (310, 130), such as magnets, Velcro, protrusions / ridges that can be engaged with the corresponding housing, internal and external threads, etc.

[0039] The reversible ventilator assembly of the present utility model further includes Figures 7 to 10Other accessory blanking covers (500) shown in [figure]. The blanking cover (500) is designed to be mounted on a wall support (100) to replace a ventilator (300), and its function is only to cover the first through-hole (210) or act as an adjustable passive ventilation device through its sealing cover (530). This configuration provides strong versatility for any compartment equipped with multiple reversible ventilator components, allowing individual selection of adjustable active / passive ventilation and the direction of air intake and exhaust at each location. To this end, the blanking cover (500) includes first coupling means (310) that are identical to the first coupling means of the ventilator (300) so as to be coupled to the wall support (100) equally conveniently. The blanking cover (500) further includes two internal structures, a partition (520) and a fourth through-hole (510): the partition (520) further includes a hole (522), and a pivot pin on the inner side of the sealing cover (530) is also shown in the figure, which is rotatably mounted on the partition (520). The pivot pin is located on the hidden surface of the blanking cover (530) and fitted into the hole (522) (not shown in the figure). In this way, the sealing cover (530) can be rotated to fully or partially open or close the fourth through-hole (510). Therefore, the sealing cover (530) includes a sealing portion (550) and a vent portion (540). By aligning one of the sealing portion (550) and the vent portion (540) with the fourth through-hole (510) of the blanking cover (500), it allows or does not allow part or all of the air to pass through.

[0040] The sealing cover (530) may further include a flange or rib-shaped member (560) for strengthening the vent portion (540) and also serving as a gripping portion for the vent portion (540) and the sealing portion (550) so that the sealing cover (530) can be easily rotated by hand. The important technical feature in this case is that the sealing cover (530) can be rotated relative to the blanking cover (500), and this can be achieved by means other than those described in this paragraph. For example, the outer circumference of the sealing cover (530) and the receiving circumference of the blanking cover (500) are snap-fitted along the receiving circumference.

[0041] In Figure 7 [figure], the sealing portion (550) has rib-shaped members (560) arranged in a first direction. The rib-shaped members (560) of the sealing portion (550) are arranged in the first direction, and the rib-shaped members (560) are almost horizontally visible on the right side of the sealing cover (530); other rib-shaped members (560) are arranged in another direction, and the rib-shaped members (560) are visible on the upper side of the sealing cover (530); this different arrangement is for design reasons and can be the same throughout the sealing portion (550), or each rib-shaped member (560) can have a different direction, or according to the direction of the rib-shaped members (560), different from Figure 7They are grouped in the manner shown. It is understood that different arrangements of the rib-shaped components (560) are protected according to the description of the corresponding claims, and the different arrangements do not affect the essence of this technical feature. In other embodiments, the rib-shaped components (560) of the sealing part (550) can be flange components of any shape, discontinuous strips, circles or any other shape, etc., for easy grasping when rotating the sealing cover (530).

[0042] According to another embodiment of the present utility model, referring to Figure 11 and Figure 12 as shown, the reversible ventilator assembly may include a mounting fitting using an extension coupling (600). The extension coupling (600) is equipped with a plurality of first coupling devices (310), which are the same as the coupling devices of other components such as the exhaust machine (300) or the blind cover (500), and have the same numerical representation, so that the first coupling devices (310) are coupled to the wall support (100). The extension coupling (600) is suitable for being fixed at the other end opposite to the fixed point of the wall support (100), and the air duct (700) can be coupled according to the steps shown in (a) to (d) of Figure 13 . The air duct (700) can be any duct suitable for such purposes and any duct already available in the market for the air duct system. Therefore, a smooth, corrugated, flexible / rigid, or any combination of characteristics can be adopted. Figure 13 As shown, it is fixed on the extension coupling (600) by a flange, but any suitable method can also be used, such as using friction, snap fit, button snap, screws, etc., or any combination of the above. Figure 13 The use of an air actively conveying element is also shown in (b) to (d) of

[0043] Figure 14 and Figure 15 show two non-limiting embodiments of the ventilator assembly of the present utility model. Specifically,[[]] Figure 14 shows a compartment or cabinet, in which two groups of ventilators have been installed, one on the ceiling of the cabinet and the other at the bottom of one of the side walls (200). In this case, the above-mentioned extension coupling (600) has been installed on the wall support (100), and then the air duct (700) and the active air flow exhaust / suction device (the arrows in the figure indicate the air flow direction). Figure 15Another application example is shown. In this case, a ventilator (300) is equipped; usually, a ventilator (300) acting as an exhaust device and another ventilator (300) acting as an intake device are assembled, and it is also possible to optionally install multiple devices (300) with exhaust and intake functions, depending on the ventilation speed requirements or the compartment size within the compartment.

[0044] Finally, it should be noted that the round shapes of the wall support (100), the sealing covers (500, 530), the ventilator (300), and the extension coupling (600), etc., are only consistent with the embodiments described herein, and they can be different, but always comply with the technical features disclosed in the claims.

[0045] In summary, the present utility model is generally applicable to any room where it is necessary to form an intake and / or exhaust ventilation airflow on walls, partitions, ceilings, etc. for various reasons. Therefore, the present utility model is applicable to cabinet bodies, music rehearsal rooms, special entertainment rooms, industrial isolation rooms (isolating noise, gases, or the like), meditation rooms (or any room where it is desired to achieve sensory isolation from the outside world), mobile toilets, laboratories, etc.
