Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a humidifier fixing device and a ventilator. Background Technology

[0002] The humidifier is an important component that provides a constant humidity gas to the ventilator. It is used to add an appropriate amount of water vapor to the relatively dry gas after it has been compressed by the ventilator to achieve the ideal humidity.

[0003] However, in most existing home ventilator products, the humidifier canister is usually secured with simple plastic clips. When disassembling the humidifier canister, it is often necessary to press the plastic clips forcefully to deform them before the canister can be removed, which is inconvenient. Summary of the Invention

[0004] In order to at least overcome the above-mentioned deficiencies in the prior art, the purpose of this application is to provide a humidification tank fixing device and a ventilator.

[0005] In a first aspect, embodiments of this application provide a humidification tank fixing device, which includes a housing, a mounting component, a limiting component, and a rotating locking component.

[0006] The housing includes a receiving cavity for accommodating a humidification canister, the receiving cavity including a bottom, wherein the humidification canister is inserted or removed in a direction perpendicular to the bottom.

[0007] The mounting component is disposed at the bottom, and the limiting component and the rotating locking component are fixed on the mounting component.

[0008] The rotating locking assembly includes a rotating disk, a locking part, and a rotating power component. The rotating disk can rotate relative to the mounting assembly via the rotating power component. The locking part is located on the rotating disk and is used to engage with the buckle of the humidification tank to lock or unlock.

[0009] The limiting component controls the rotation of the rotating disk by whether or not it limits the rotation of the rotating disk. When the limiting component limits the rotation of the rotating disk to its reset position, the locking part on the rotating disk and the buckle of the humidification tank are locked. When the limiting component does not limit the rotation of the rotating disk, the locking part on the rotating disk and the buckle of the humidification tank are unlocked.

[0010] In one possible implementation, the mounting assembly includes a first mounting wall and a second mounting wall connected to each other, wherein both the first mounting wall and the second mounting wall are perpendicular to the bottom.

[0011] The limiting component is installed on the first mounting wall, and the rotating locking component is installed on the second mounting wall. The limiting component is telescopic relative to the first mounting wall, the rotating disk is parallel to the second mounting wall, and the rotating disk is rotatable relative to the second mounting wall.

[0012] In one possible implementation, the limiting component includes a limiting pin and an elastic element. The first mounting wall is provided with a limiting through hole to limit the movement direction of the limiting pin. The limiting pin is disposed towards the rotating disk after passing through the limiting through hole. A first limiting part is provided at one end of the limiting pin facing the rotating disk to limit the rotation disk.

[0013] The limiting pin is also provided with a blocking part. The elastic element surrounds the outside of the limiting through hole and is located between the first mounting wall and the blocking part. The length of the elastic element in the direction perpendicular to the first mounting wall is greater than the protrusion height of the limiting through hole relative to the first mounting wall.

[0014] In one possible implementation, the rotating disk includes a second limiting part and a third limiting part;

[0015] The second limiting part is located near the edge of the rotating disk and is arranged along the rotation direction of the rotating disk. The second limiting part is used to cooperate with the first limiting part to control the rotation of the rotating disk.

[0016] The third limiting part extends toward the center of the rotating disk, and the third limiting part is used to cooperate with the first limiting part to limit the rotation angle of the rotating disk.

[0017] In one possible implementation, the second limiting portion is disposed on the side of the rotating disk away from the second mounting wall and protrudes relative to the rotating disk, and the end of the second limiting portion includes a chamfer.

[0018] In one possible implementation, the locking part includes a notch in the rotating disk, the notch including a first side away from the second limiting part and a second side near the second limiting part, the distance between the first side and the center of the rotating disk being greater than the distance between the second side and the center of the rotating disk.

[0019] In one possible implementation, the second mounting wall includes a fixed shaft;

[0020] The rotating disk includes a rotating through hole that mates with the fixed shaft and a fixing member disposed on the side of the rotating disk near the second mounting wall. The fixing member is used to fix the rotating power member, and the rotating disk rotates around the fixed shaft under the action of the rotating power member.

[0021] In one possible implementation, the rotational power element includes a torsion spring, and the elastic element includes a spring.

[0022] In one possible implementation, the humidification tank fixing device further includes a button disposed on the outside of the housing, the button being connected to the end of the limiting component away from the first limiting portion.

[0023] Secondly, embodiments of this application also provide a ventilator, the ventilator including any of the humidifier fixing devices described in the first aspect.

[0024] Based on any of the above aspects, the humidifier fixing device and ventilator provided in this application include a limiting component and a rotating locking component. The rotating locking component includes a rotating disk, a locking part, and a rotating power component. The rotating disk can rotate relative to the mounting component via the rotating power component. The locking part is located on the rotating disk and is used to engage with the humidifier's latch to lock or unlock. The limiting component controls the rotation of the rotating disk by limiting its rotation. When the limiting component limits the rotation of the rotating disk to its reset position, the locking part on the rotating disk is locked to the humidifier's latch. When the limiting component does not limit the rotation of the rotating disk, the locking part on the rotating disk is unlocked to the humidifier's latch. The locking part can lock or unlock the humidifier's latch through the combined action of the rotating disk, the rotating power component, and the limiting component, simplifying the installation or removal process of the humidifier and improving user experience and work efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0040] Please refer to Figure 1 This application provides a humidification tank fixing device, including a housing 110, a mounting assembly 120, a limiting assembly 130, and a rotating locking assembly 140.

[0041] The housing 110 includes a receiving cavity 111 for accommodating the humidification tank 200, the receiving cavity 111 including a bottom, wherein the humidification tank 200 is inserted or removed in a direction perpendicular to the bottom.

[0042] Mounting assembly 120 is located at the bottom, and limiting assembly 130 and rotating locking assembly 140 are fixed on mounting assembly 120, thereby connecting limiting assembly 130 and rotating locking assembly 140 to housing 110 through mounting assembly 120.

[0043] The rotating locking assembly 140 includes a rotating disk 141, a locking part 142, and a rotating power member 143. The rotating disk 141 can rotate relative to the mounting assembly 120 via the rotating power member 143. The locking part 142 is located on the rotating disk 141 and is used to engage with the latch of the humidification tank 200 to lock or unlock. Specifically, when the humidification tank 200 is inserted from the right side of the bottom in a direction perpendicular to the bottom, the rotating disk 141 can rotate clockwise under the action of the humidification tank 200 until the locking part 142 and the latch of the humidification tank 200 are locked. When it is necessary to replace the humidification tank 200, the rotating disk 141 can rotate counterclockwise under the action of the rotating power member 143 (i.e., reset rotation) until the locking part 142 unlocks and ejects the humidification tank 200. Similarly, when the humidifier 200 is inserted from the left side of the bottom in a direction perpendicular to the bottom, the rotating disk 141 can rotate counterclockwise under the action of the humidifier 200 until the locking part 142 and the humidifier 200 are locked together. When it is necessary to replace the humidifier 200, the rotating disk 141 can rotate clockwise under the action of the rotating power member 143 (i.e., reset rotation) until the locking part 142 unlocks and ejects the humidifier 200.

[0044] The limiting component 130 controls the rotation of the rotating disk 141 by whether or not it limits the rotation of the rotating disk 141. When the limiting component 130 limits the rotation of the rotating disk 141 to its reset position, the locking part 142 on the rotating disk 141 is locked to the latch of the humidification tank 200. When the limiting component 130 does not limit the rotation of the rotating disk 141, the locking part 142 on the rotating disk 141 is unlocked from the latch of the humidification tank 200.

[0045] Specifically, taking the case where the humidifier 200 is inserted from the right side of the bottom in a direction perpendicular to the bottom as an example, the rotating disk 141 can rotate clockwise under the action of the humidifier 200. The rotational power component 143 will generate a rotational force to attempt to return to the initial state (i.e., reset rotation). In order to keep the locking part 142 on the rotating disk 141 locked to the latch of the humidifier 200, the limiting component 130 needs to limit the reset rotation of the rotating disk 141 to prevent the rotating disk 141 from resetting under the action of the rotational power component 143. Based on the above principle, when it is necessary to disassemble the humidifier 200, the limiting effect of the limiting component 130 on the rotating disk 141 can be released, allowing the rotating disk 141 to reset under the action of the rotational power component 143, thereby unlocking the latch of the locking part 142 on the humidifier 200. It should be noted that after the locking part 142 unlocks and pops out the humidification tank 200, the limiting component 130 can also limit the rotation of the rotating disk 141 to prevent the rotating disk 141 from rotating too much under the action of the rotating power component 143, which would affect the next operation of the locking part 142 and improve stability and reliability.

[0046] In this embodiment, the locking part 142 can lock or unlock the humidification tank 200 latch through the combined action of the rotating disk 141, the rotating power component 143, and the limiting component 130, simplifying the installation or disassembly process of the humidification tank 200 and improving user experience and work efficiency. Furthermore, when the locking part 142 and the humidification tank 200 latch are in the locked state, the limiting component 130 can prevent the rotating disk 141 from reversing and rotating under the action of the rotating power component 143, thereby preventing the humidification tank 200 from loosening or falling out, and improving equipment safety.

[0047] Please refer to Figure 2 As one possible implementation of this application embodiment, the mounting assembly 120 includes a first mounting wall 121 and a second mounting wall 122 connected to each other, wherein both the first mounting wall 121 and the second mounting wall 122 are perpendicular to the bottom. A limiting assembly 130 is mounted on the first mounting wall 121, and a rotating locking assembly 140 is mounted on the second mounting wall 122. The limiting assembly 130 can extend and retract relative to the first mounting wall 121 to limit the rotating disk 141. For example, when it is necessary to disassemble the humidification tank 200, the limiting assembly 130 can be compressed in the direction of the rotating locking assembly 140 to release the limiting effect of the limiting assembly 130 on the rotating disk 141. The rotating disk 141 is parallel to the second mounting wall 122 and can rotate relative to the second mounting wall 122. For example, when the humidification tank 200 is inserted from the right side of the bottom in a direction perpendicular to the bottom, the rotating disk 141 can rotate clockwise under the action of the humidification tank 200. When the limiting component does not limit the rotating disk 141, the rotating disk 141 can be reset and rotated in the opposite direction (i.e., counterclockwise) under the action of the rotation power member 143, so that the locking part 142 pops out the humidification tank 200.

[0048] Furthermore, the mounting assembly 120 may also include a third mounting wall perpendicular to the first mounting wall 121 and the second mounting wall 122. The third mounting wall is mounted on the bottom of the housing 110 to improve the connection stability between the limiting assembly 130 and the rotating locking assembly 140 and the housing 110, thereby increasing their service life.

[0049] Please refer to Figure 3 As one possible implementation of this application embodiment, the limiting component 130 may include a limiting pin 131 and an elastic element 132. The first mounting wall 121 is provided with a limiting through hole to limit the movement direction of the limiting pin 131. The limiting pin 131 is disposed towards the rotating disk 141 after passing through the limiting through hole. A first limiting part 1311 is provided at one end of the limiting pin 131 facing the rotating disk 141 to limit the rotating disk 141. Specifically, the first limiting part 1311 may protrude relative to the surface of the limiting pin 131.

[0050] Further, please refer to Figure 4 The limiting pin 131 is also provided with a blocking part 1312. The elastic member 132 surrounds the outside of the limiting through hole and is located between the first mounting wall 121 and the blocking part 1312. The length of the elastic member 132 in the direction perpendicular to the first mounting wall 121 is greater than the protrusion height of the limiting through hole relative to the first mounting wall 121. For example, the elastic member 132 can be a spring.

[0051] In the above structure, when the locking part 142 and the humidification tank 200 are locked, the first limiting part 1311 can limit the reset rotation of the rotating disk 141, preventing the rotating disk 141 from reversing its reset rotation under the action of the rotating power member 143. This prevents the humidification tank 200 from becoming loose or falling out, thus improving equipment safety. When disassembling the humidification tank 200, the limiting pin 131 can be moved towards the center of the rotating disk 141 by squeezing the elastic member 132, releasing the limiting effect of the first limiting part 1311 on the rotating disk 141. This allows the rotating disk 141 to reset its rotation under the action of the rotating power member 143 until the locking part 142 unlocks and ejects the humidification tank 200. In addition, after the locking part 142 unlocks and ejects the humidification tank 200, the limiting component 130 can also limit the rotating disk 141 to prevent the rotating disk 141 from rotating too much under the action of the rotating power member 143, which would affect the next operation of the locking part 142, thereby improving stability and reliability.

[0052] Please refer to Figure 5 As one possible implementation of this application embodiment, the rotating disk 141 includes a second limiting part 1411 and a third limiting part 1412. The second limiting part 1411 is disposed near the edge of the rotating disk 141 along the rotation direction of the rotating disk 141, and is used to cooperate with the first limiting part 1311 to control the rotation of the rotating disk 141. The third limiting part 1412 extends towards the center of the rotating disk 141, and is used to cooperate with the first limiting part 1311 to limit the rotation angle of the rotating disk 141. Specifically, when the locking part 142 and the latch of the humidification tank 200 are in the locked state, the rotation of the rotating disk 141 can be limited by the cooperation of the first limiting part 1311 and the second limiting part 1411, preventing the rotating disk 141 from reversing its rotation under the action of the rotation power member 143 (see details). Figure 6 This prevents the humidification tank 200 from becoming loose or detached, thus improving equipment safety. After the locking part 142 unlocks and the humidification tank 200 is ejected, the rotation angle of the rotating disk 141 can be limited by the cooperation of the first limiting part 1311 and the third limiting part 1412 (please refer to [reference] for details). Figure 7This is to prevent the rotating disk 141 from rotating too much under the action of the rotating power component 143, which would affect the next operation of the locking part 142, and to improve stability and reliability.

[0053] Furthermore, the second limiting part 1411 is disposed on the side of the rotating disk 141 away from the second mounting wall 122, and protrudes relative to the rotating disk 141. The end of the second limiting part 1411 includes a chamfer, which is used to cooperate with the first limiting part 1311 to limit the reset rotation of the rotating disk 141. Specifically, when the rotating disk 141 rotates to a certain position under the action of the humidification tank 200, that is, when the locking part 142 and the humidification tank 200 are just locked, the chamfer of the first limiting part 1311 and the second limiting part 1411 cooperates to limit the reset rotation of the rotating disk 141. Alternatively, the end of the second limiting part 1411 can be made into a stepped shape by reducing its width, so as to limit the reset rotation of the rotating disk 141 by cooperating with the first limiting part 1311.

[0054] Furthermore, the locking part 142 includes a notch in the rotating disk 141. The notch includes a first side away from the second limiting part 1411 and a second side near the second limiting part 1411. The distance between the first side and the center of the rotating disk 141 is greater than the distance between the second side and the center of the rotating disk 141. With this configuration, when the humidifier 200 is inserted from the right side of the bottom in a direction perpendicular to the bottom, it can more easily push the rotating disk 141 to rotate clockwise. Similarly, when the humidifier 200 is inserted from the sitting side of the bottom in a direction perpendicular to the bottom, it can more easily push the rotating disk 141 to rotate counterclockwise.

[0055] As one possible implementation of this application embodiment, the second mounting wall 122 includes a fixed shaft.

[0056] The rotating disk 141 includes a rotating through hole 1413 that cooperates with a fixed shaft and a fixing member 1414 disposed on the side of the rotating disk 141 near the second mounting wall 122. The fixing member 1414 is used to fix the rotating power member 143. The rotating disk 141 rotates around the fixed shaft under the action of the rotating power member 143. For example, the rotating power member 143 can be a torsion spring.

[0057] Furthermore, the humidification tank fixing device also includes a button located on the outside of the housing 110. The button is connected to the end of the limiting component 130 away from the first limiting part 1311. By pressing the button, the elastic element 132 can be compressed, releasing the limiting effect of the first limiting part 1311 on the rotating disk 141. This allows the rotating disk 141 to be reset and rotated under the action of the rotating power component 143 until the locking part 142 unlocks and pops out the humidification tank 200. This reduces excessive manual intervention, improves the automation level of the equipment, and increases work efficiency.

[0058] Based on the same inventive concept, this application also provides a ventilator, including a humidifier 200 and the aforementioned humidifier fixing device. The humidifier fixing device can simplify the operation process of installing and / or removing the humidifier 200 and improve work efficiency.

[0059] In summary, this application provides a humidifier tank fixing device and a ventilator. The humidifier tank fixing device includes a limiting component and a rotating locking component. The rotating locking component includes a rotating disk, a locking part, and a rotating power component. The rotating disk can rotate relative to the mounting component via the rotating power component. The locking part is located on the rotating disk and is used to engage with the humidifier tank's latch to lock or unlock. The limiting component controls the rotation of the rotating disk by limiting its rotation. When the limiting component limits the rotation of the rotating disk to its reset position, the locking part on the rotating disk is locked to the humidifier tank's latch. When the limiting component does not limit the rotation of the rotating disk, the locking part on the rotating disk is unlocked to the humidifier tank's latch. The locking part can lock or unlock the humidifier tank's latch through the combined action of the rotating disk, the rotating power component, and the limiting component, simplifying the installation or removal process of the humidifier tank and improving user experience and work efficiency.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
