Description
Technical Field
The invention relates to the technical field of motors, in particular to a ventilation fan with a mask.
Background
Referring to fig. 1, a conventional ventilator 9 includes: a ventilator cover 91 and a ventilator body 92. The ventilator cover 91 includes a frame 911 and a cover plate 912, the frame 911 is combined with the ventilator body 92, and the cover plate 912 is detachably combined with the frame 911. The cover plate 912 can shield the ventilator body 92 to prevent foreign objects or mosquitoes from entering the ventilator body 92. An embodiment of the conventional ventilation fan 9 is disclosed in the patent of "ventilation fan" in chinese publication No. CN 202402369.
The cover plate 912 is fixedly fastened to the frame 911 by means of a latch or a hook, or is fixedly fastened to the frame 911, so that when a user wants to remove the cover plate 912 to perform maintenance (for example, cleaning, replacing a filter screen or maintaining a fan) on the ventilator body 92 of the frame 911, the user must sequentially release the fastening or fastening portion between the cover plate 912 and the frame 911 to remove the cover plate 912, which results in a long time and expense for removing the cover plate 912. Moreover, the conventional ventilation fan 9 is usually disposed at a high level, so that it is very difficult to remove the cover plate 912 in practical implementation.
Therefore, some conventional ventilation fans have been replaced with other coupling structures that facilitate easy attachment and detachment, such as a magnet that magnetically couples the cover plate 912 to the housing 911. Therefore, when a user wants to remove the cover plate 912 to maintain the frame 911 or the ventilator body 92, the user only needs to pull the cover plate 912 to overcome the magnetic attraction of the magnet, and then the cover plate 912 can be removed from the frame 911, so as to remove the cover plate 912.
However, when the user wants to put the cover plate 912 back on, each magnet must be aligned with and close to a magnetic part (e.g., iron plate or another magnet) to magnetically attach the cover plate 912 to the frame 911. As described above, since the conventional ventilation fan is usually installed at a high level, the cover plate 912 is still difficult to be installed and removed, which results in poor usability of the conventional ventilation fan using a coupling structure such as a magnet that is easy to be installed and removed.
Moreover, although the magnets can provide a longitudinal magnetic attraction force to magnetically attach the cover plate 912 to the frame 911, the magnets cannot provide a lateral support force. Therefore, once the cover plate 912 is subjected to a lateral external force, the cover plate 912 may be displaced and fall off. Moreover, since the ventilation fan can be installed in a space such as a bathroom or a toilet, the operation environment thereof is likely to change alternately between a high temperature and a low temperature, and is continuously affected by the temperature change, the gravity, and the like, and the cover plate 912 is likely to be deformed when used for a long time. Accordingly, the conventional ventilation fan using a coupling structure such as a magnet, which is easy to assemble and disassemble, has poor structural strength.
In addition, if the deformation degree of the cover plate 912 is too severe, the change range of the distance between the magnet or the magnetic attraction part is too large, which will cause that the cover plate 912 cannot be installed back, resulting in a poor service life of the existing ventilation fan using a combination structure such as a magnet which is convenient to assemble and disassemble; and, the said magnet is exposed, so if the existing scavenger fan is set up in the space (for example: the bath toilet) with higher humidity, the said magnet is apt to produce the corrosion, also cause the life cycle of the existing scavenger fan which adopts the easy-to-dismount combined structure such as the magnet, etc. to be shorter.
Accordingly, there is a need for an improved ventilation fan to overcome the above-mentioned shortcomings of the prior art.
Disclosure of Invention
In order to solve the above problems, the present invention provides a ventilation fan, wherein a plurality of second connectors of a cover plate are combined with a plurality of first connectors of a frame body, so that a cover body is detachably combined with the frame body.

Detailed Description
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below:
referring to fig. 2 and 3, a ventilator according to a first embodiment of the present invention includes a main body 1 and a housing 2. The outer cover 2 is combined on the body 1.
The body 1 includes a fan 11, the fan 11 has an axial direction X, and the fan 11 includes an air flow opening 111, the air flow opening 111 being formed at one side of the fan 11 in the axial direction X.
The housing 2 includes a frame 21 and a cover 22, the frame 21 has a plurality of first positioning portions 211, and each first positioning portion 211 has a first coupling member 212. The cover plate 22 is provided with a plurality of second positioning portions 221, and each second positioning portion 221 is provided with one second coupling member 222. The first combining member 212 and the second combining member 222 are each a magnetizer, and at least one of the first combining member 212 and the second combining member 222 is a permanent magnet. Therefore, the second engaging members 222 of the second positioning portions 221 can respectively magnetically engage with the first engaging members 212 of the first positioning portions 211, so that the cover 22 can be detachably engaged with the frame 21.
One of the first positioning portion 211 and the second positioning portion 221 is a tube, and the other of the first positioning portion 211 and the second positioning portion 221 is a cylinder extending into the tube along the axial direction X. For example, referring to fig. 4, an enlarged cross-sectional view of the first positioning portion 211 and the second positioning portion 221 is shown, in this embodiment, the first positioning portion 211 is a tube a, the second positioning portion 221 is a column B, and the column B extends into the tube a along the axial direction X. The first connecting member 212 is coupled to the inside of the first positioning portion 211; the second engaging member 222 is engaged with a side of the second positioning portion 221 adjacent to the frame body 21 in the axial direction X. Therefore, when the second positioning portion 221 extends into the first positioning portion 211 along the axial direction X, the second engaging member 222 can be adjacent to the first engaging member 212.
In this embodiment, the first engaging member 212 may be a magnetic conductor made of soft magnetic material, and the second engaging member 222 is a permanent magnet, so that when the second engaging member 222 is adjacent to the first engaging member 212, the second engaging member 222 can be magnetically engaged with the first engaging member 212. It should be noted that the first coupling member 212 may be a screw made of a soft magnetic material, so that the first coupling member 212 can be fastened to the first positioning portion 211 by screwing, so that the first coupling member 212 can be quickly and stably fastened to the first positioning portion 211.
However, referring to fig. 5, which is an enlarged sectional view of the ventilator according to the second embodiment of the present invention, the first positioning portion 211 and the second positioning portion 221 are different from the first embodiment in that: the first positioning portion 211 is a cylinder B, the second positioning portion 221 is a tube a, and the cylinder B extends into the tube a along the axial direction X. The first coupling member 212 is coupled to a side of the first positioning portion 211 adjacent to the cover plate 22 in the axial direction X; the second coupling member 222 is coupled to the inside of the second positioning portion 221. Therefore, after the first positioning portion 211 extends into the second positioning portion 221 along the axial direction X, the second engaging member 222 can be adjacent to the first engaging member 212. In addition, in the embodiment, the first engaging member 212 can be a permanent magnet, and the second engaging member 222 can be a magnetic conductor (e.g., an iron sheet) made of a soft magnetic material, so that when the second engaging member 222 is adjacent to the first engaging member 212, the second engaging member 222 can be magnetically coupled to the first engaging member 212. Alternatively, in some embodiments of the present invention, the first engaging element 212 and the second engaging element 222 can be both permanent magnets to enhance the magnetic attraction between the first engaging element 212 and the second engaging element 222.
With the above structure, as shown in fig. 3, when the ventilating fans of the first and second embodiments of the present invention are actually used, the main body 1 can be installed on an isolation member D, which can be a ceiling or a wall of a building. The housing 2 may be provided with a through slot 21a, the through slot 21a is communicated with the airflow opening 111 of the fan 11, and a ventilation opening 23 is formed between the frame body 21 and the cover plate 22. Accordingly, when the fan 11 is operated, air flow can be introduced through the ventilation opening 23, the through groove 21a and the air flow opening 111 to provide ventilation function. In addition, the cover plate 22 can be magnetically coupled to the first coupling member 212 of the frame 21 through the second coupling members 222, so as to be detachably coupled to the frame 21. Therefore, when a user wants to remove the cover 22 to maintain the frame 21 or the main body 1, the user only needs to pull the cover 22 to overcome the magnetic attraction between the second engaging members 222 and the first engaging members 212, so as to remove the cover 22 from the frame 21.
Because the first coupling member 212 is coupled to the first positioning portion 211, the second coupling member 222 is coupled to the second positioning portion 221, one of the first positioning portion 211 and the second positioning portion 221 is a tube a, and the other of the first positioning portion 211 and the second positioning portion 221 is a cylinder B, and the cylinder B extends into the tube a along the axial direction X. Accordingly, when the user wants to mount the cover 22 back, the user only needs to extend the column B into the tube a, so that the second engaging member 222 abuts and magnetically engages with the first engaging member 212. The ventilation fans of the first and second embodiments can enable a user to quickly magnetically couple the second coupling members 222 to the first coupling members 212, so as to improve the convenience of use of the ventilation fans.
Besides, in the ventilation fans of the first and second embodiments, the second connectors 222 and the first connectors 212 provide longitudinal magnetic attraction force, and the column B of the first positioning portion 211 and the second positioning portion 221 extends into the tube a along the axial direction X, so that the first positioning portion 211 and the second positioning portion 221 can provide lateral support force, so that the cover plate 22 is not easy to displace or fall off when bearing lateral external force, and the cover plate 22 can be effectively prevented from deforming after long-term use, thereby improving the structural strength of the ventilation fan.
In addition, the column B in the first positioning portion 211 and the second positioning portion 221 extends into the tube a along the axial direction X, so that even if the cover plate 22 deforms, the first positioning portion 211 and the second positioning portion 221 can limit the deformation of the cover plate 22, and the change of the distance between the second positioning portions 221 is avoided, so as to avoid the situation that the cover plate 22 cannot be installed back, thereby prolonging the service life of the ventilation fan. Moreover, when the first coupling member 212 and the second coupling member 222 of the ventilation fans of the first embodiment and the second embodiment are magnetically coupled to each other, the first coupling member 212 and the second coupling member 222 are accommodated inside the column B of the first positioning portion 211 and the second positioning portion 221, so that the first positioning portion 211 and the second positioning portion 221 can effectively cover and protect the first coupling member 212 and the second coupling member 222, thereby preventing the first coupling member 212 and the second coupling member 222 from being rusted, and further prolonging the service life of the ventilation fans.
Based on the above technical concept, the features of the ventilation fan according to the embodiments of the present invention are listed below and described in detail:
referring to fig. 4, in the ventilation fan of the first embodiment, the first positioning portion 211 has a bottom surface 213 facing the cover 22, and the first combining member 212 is combined on the bottom surface 213. Since the first coupling member 212 can be a screw made of soft magnetic material in the first embodiment, the first coupling member 212 can be locked on the bottom surface 213 to be locked on the first positioning portion 211. The second positioning portion 221 is provided with a second accommodating groove 224 on a side adjacent to the frame 21 in the axial direction X, and the second engaging member 222 is engaged in the second accommodating groove 224. Therefore, by combining the first coupling member 212 with the bottom surface 213 and at least partially receiving the second coupling member 222 in the second receiving groove 224, a space can be reserved in the tube a of the first positioning portion 211 for the column B of the second positioning portion 221 to extend into, and the first positioning portion 211 and the second positioning portion 221 are ensured to overlap on a plane perpendicular to the axial direction X.
Similarly, referring to fig. 5, in the ventilation fan of the second embodiment, a first receiving groove 214 is formed on a side of the first positioning portion 211 adjacent to the cover plate 22 in the axial direction X, and the first combining member 212 is combined in the first receiving groove 214. The second positioning portion 221 has a bottom surface 223 facing the frame 21, and the second coupling member 222 is coupled to the bottom surface 223. Therefore, by combining the second joint member 222 with the bottom surface 223 and at least partially accommodating the first joint member 212 in the first accommodating groove 214, a space can be reserved in the tube a of the second positioning portion 221 for the column B of the first positioning portion 211 to extend into, and the first positioning portion 211 and the second positioning portion 221 are ensured to overlap on a plane perpendicular to the axial direction X.
Referring to fig. 6, in some embodiments of the present invention, if the first positioning portion 211 is a cylinder B, the first positioning portion 211 can further have a through hole 215, and the through hole 215 is connected to the first receiving slot 214, so that the first connecting member 212 can be easily combined in the first receiving slot 214. Moreover, the side of the through hole 215 away from the first accommodating groove 214 can be used for injecting glue to the first bonding member 212 to form a glue G, so as to firmly fix the first bonding member 212 in the first accommodating groove 214. Wherein, the through hole 215 can form a diameter reduction shape relative to the first container 214, so that the first connecting element 212 can be positioned in the first container 214; however, the through hole 215 may also have the same diameter as the first accommodating groove 214, so that the first positioning portion 211 can be combined with the first combining member 212 having different lengths, which is not limited by the invention. Similarly, if the second positioning portion 221 is a cylinder B, the second positioning portion 221 may also be provided with a through hole (not shown) communicating with the second receiving groove 224 thereof, so that the second joint member 222 can be easily combined in the second receiving groove 224.
Referring to fig. 7, in some embodiments of the present invention, if the first positioning portion 211 is a tube a, the first positioning portion 211 can also be provided with a through hole 215, and the through hole 215 penetrates through the bottom surface 213, so that the first connecting member 212 can be easily inserted into the tube a and combined with the bottom surface 213. Moreover, the side of the through hole 215 away from the bottom surface 213 can be used for injecting glue to the first bonding member 212 to form a glue G, so as to firmly fix the first bonding member 212 on the bottom surface 213. Similarly, if the second positioning portion 221 is a tube a, the second positioning portion 221 may also be provided with a through hole (not shown) penetrating through the bottom surface 223 thereof, so that the second joint member 222 can be easily inserted into the tube a and combined with the bottom surface 223.
Referring to fig. 8 and 9, in the ventilation fan according to the third embodiment of the present invention, in the present embodiment, the tube a of the first positioning portion 211 and the second positioning portion 221 has a height H1, the height H1 is a distance from the tube opening of the tube a to the bottom surfaces 213 and 223 (in the present embodiment, the bottom surface 223), and a length H2 of the column B of the first positioning portion 211 and the second positioning portion 221 extending into the tube a is preferably greater than or equal to 0.25 times of the height H1, so that an overlapping portion of the first positioning portion 211 and the second positioning portion 221 on a plane perpendicular to the axial direction X is large enough to ensure that the first positioning portion 211 and the second positioning portion 221 can provide a good lateral supporting force.
On the other hand, in the present embodiment, the outer diameter of the first coupling member 212 may be smaller than the inner diameter of the first receiving groove 214, so that the first coupling member 212 can be tightly fitted into the first receiving groove 214.
As shown in fig. 6, the first positioning portion 211 and the column B of the second positioning portion 221 may abut against the inner peripheral wall of the tube a; in other words, the inner diameter of the tube a may be equal to the outer diameter of the cylinder B to improve the positioning and supporting effects of the first positioning portion 211 and the second positioning portion 221. However, as shown in fig. 7, in some embodiments of the present invention, the inner diameter of the tube a is preferably greater than or equal to 1.1 times the outer diameter of the cylinder B, so that the cylinder B and the tube a can form a gap to ensure that the cylinder B can extend into the tube a without obstruction. In addition, even if the cover plate 22 is deformed to change the distance between the second positioning portions 221, as long as the distance change range of the second positioning portions 221 is within an allowable range, the cylinder B can still extend into the tube a, so as to avoid the situation that the cover plate 22 cannot be installed back.
Alternatively, as shown in fig. 9, in the third embodiment, an enlarged diameter portion a1 may be provided at the position of the opening end of the tube body a such that the inner diameter of the tube body a increases at the enlarged diameter portion a 1. The tube body A has a maximum inner diameter W1, the maximum inner diameter W1 is preferably greater than or equal to 1.1 times the outer diameter W2 of the column body B, so that the column body B can extend into the tube body A without obstruction; on the other hand, after the cylinder B passes through the expanded diameter portion a1, the cylinder B still abuts against the inner peripheral wall of the tube a, so as to improve the positioning and supporting effects of the first positioning portion 211 and the second positioning portion 221.
Referring to fig. 10, in another state of the third embodiment, the first positioning portion 211 can further have a ring protrusion 211a extending toward the first receiving groove 214, one end of the first coupling member 212 can have a reduced diameter portion 212a, the first coupling member 212 has a shoulder portion 212b connected to the reduced diameter portion 212a, and the ring protrusion 211a surrounds the reduced diameter portion 212 a. Therefore, the first connecting element 212 can be inserted into the first positioning portion 211 through the through hole 215, such that the ring protrusion 211a surrounds the reduced diameter portion 212a, and the shoulder 212b abuts against the ring protrusion 211a to position the first connecting element 212. Therefore, the first engaging element 212 can be stably positioned in the first receiving groove 214 without tightly fitting and engaging the first positioning portion 211. In addition, the two ends of the first coupling member 212 may be respectively provided with the reduced diameter portion 212a, so that when the first coupling member 212 is placed in the first positioning portion 211 in different directions, the annular protrusion 211a can surround the reduced diameter portion 212a, and the shoulder portion 212b abuts against the annular protrusion 211a, thereby effectively improving the assembly convenience of the ventilation fan.
Although in the foregoing embodiments, the first engaging member 212 and the second engaging member 222 are each a magnetic conductor, and at least one of the first engaging member 212 and the second engaging member 222 is a permanent magnet, so that the second engaging member 222 of each second positioning portion 221 can magnetically engage with the first engaging member 212 of each first positioning portion 211. However, referring to fig. 11 and 12, a ventilation fan according to a fourth embodiment of the present invention is different from the aforementioned embodiments in that: the first coupling member 212 and the second coupling member 222 are a press-fastening component, for example, the first coupling member 212 can be a male fastener; in contrast, the second coupling member 222 may be a female clip member, such that the male clip member of the first coupling member 212 and the female clip member of the second coupling member 222 can be pressed toward each other by an external force to be coupled or separated. However, the first coupling member 212 may be a female clip member; in contrast, the second coupling member 222 can be a male fastener, such that the female clip of the first coupling member 212 and the male fastener of the second coupling member 222 can be coupled or separated by pressing toward each other by an external force. Thereby, the second engaging members 222 of the second positioning portions 221 can still engage with the first engaging members 212 of the first positioning portions 211, so that the cover 22 can be detachably engaged with the frame 21. Accordingly, in the ventilation fan according to the embodiment of the present invention, the coupling manner between the second coupling member 222 of each second positioning portion 221 and the first coupling member 212 of each first positioning portion 211 is not limited by magnetic attraction.
Referring to fig. 13 and 14, a ventilation fan according to a fifth embodiment of the present invention is different from the aforementioned embodiments in that: the outer cover 2 further has a pivot portion 24, and the pivot portion 24 is respectively coupled to the frame 21 and the cover 22, so that the cover 22 can pivot relative to the frame 21. In addition, the outer cover 2 includes two opposite ends, the first positioning portions 211 and the second positioning portions 221 are disposed at one end of the outer cover 2, and the pivot portion 24 is disposed at the other end of the outer cover 2. Therefore, a user can rotate the cover plate 22 toward the frame 21 to make the column B extend into the tube a, so that the second engaging member 222 abuts against and magnetically engages with the first engaging member 212 to engage the cover plate 22 with the frame 21; otherwise, the user can pull the cover 22 to separate the first coupling member 212 from the second coupling member 222, and rotate the cover 22 away from the frame 21, so as to perform maintenance on the frame 21 or the parts on the body 1. Therefore, the ventilation fan according to the third embodiment of the present invention can be maintained by a user without completely separating the frame 21 and the cover plate 22, and the time required for detaching the cover plate 22 can be further reduced.
In summary, in the ventilation fan according to the embodiments of the present invention, each of the first positioning portions 211 of the frame 21 is provided with one first coupling member 212, and each of the second positioning portions 221 is provided with one second coupling member 222, so that the cover 22 can be detachably coupled to the frame 21 by coupling each of the second coupling members 222 with the first coupling member 212 of the frame 21. Therefore, the cover plate 22 can be removed from the frame 21 by pulling or pushing the cover plate 22, so that the cover plate 22 can be easily removed.
Compared to the conventional ventilation fan, when the cover plate 912 is to be installed back, each magnet must be aligned with and close to a magnetic part (e.g., an iron plate or another magnet) to magnetically couple the cover plate 912 to the frame 911. When the cover 22 is to be installed back, the second engaging member 222 can be adjacent to and engaged with the first engaging member 212 by only inserting the first positioning portion 211 and the column B of the second positioning portion 221 into the tube a. Accordingly, the ventilation fan of each embodiment can enable a user to quickly combine each second combining member 222 with each first combining member 212, and indeed has the effect of improving the convenience of use of the ventilation fan.
In addition, compared to the conventional ventilator in which the magnet cannot provide a lateral supporting force, the first positioning portion 211 and the second positioning portion 221 of the ventilator according to various embodiments of the present invention can provide a lateral supporting force, so that the cover 22 is not easily displaced or falls off when bearing a lateral external force, and the cover 22 can be effectively prevented from being deformed when being used for a long time, thereby improving the structural strength of the ventilator.
In addition, the column B in the first positioning portion 211 and the second positioning portion 221 extends into the tube a along the axial direction X, so as to limit the deformation of the cover plate 22 and prevent the interval between the second positioning portions 221 from changing, so as to prevent the cover plate 22 from being installed back, thereby prolonging the service life of the ventilation fan. Moreover, compared with the conventional ventilator in which the magnet is exposed, in the ventilator according to the embodiments of the present invention, when the first coupling member 212 and the second coupling member 222 are coupled to each other, the first coupling member 212 and the second coupling member 222 are accommodated inside the column B of the first positioning portion 211 and the second positioning portion 221, so that the first positioning portion 211 and the second positioning portion 221 can effectively cover and protect the first coupling member 212 and the second coupling member 222, thereby preventing the first coupling member 212 and the second coupling member 222 from being rusted, and indeed prolonging the service life of the ventilator.
