Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to a water tank hinge structure for ventilation equipment and a ventilation equipment. Background Technology

[0002] The water tank in ventilation equipment is used to heat and humidify the ventilation gas before providing it to the patient, thereby improving their comfort. Existing water tanks, for ease of disassembly and replacement, typically use rotating components such as a shaft to achieve relative rotation between the upper and lower parts, allowing for relative opening and closing. This method of achieving relative rotation via a shaft requires a base or other components within the water tank to support the shaft, occupying some space and reducing the actual capacity of the tank. Furthermore, if the base and shaft protrude from the water tank, they may be susceptible to damage from external impacts. Utility Model Content

[0003] This utility model provides a water tank hinge structure and a ventilation device for use in ventilation equipment, in order to solve at least one of the above-mentioned technical problems.

[0004] The present invention provides a water tank hinge structure for a ventilation device, comprising a hinge member connected to the water tank of the ventilation device. The hinge member includes an integrally formed first hinge unit and a second hinge unit. The hinge member can be opened or closed so that the water tank can be opened or closed. When the hinge is in the open state, the first hinge unit and the second hinge unit pivot about their connection position to move away from each other, and the surfaces of the first hinge unit and the second hinge unit facing each other at the connection position move away from each other. When the hinge is in the closed state, the first hinge unit and the second hinge unit pivot around their connection position as the pivot axis, thereby moving closer to each other, and the surfaces of the first hinge unit and the second hinge unit facing each other at the connection position move closer to each other.

[0005] In one embodiment, the first hinge unit includes a first connecting portion, the second hinge unit includes a second connecting portion, the first side of the first connecting portion and the first side of the second connecting portion are connected to each other, and a bending portion is provided at the connection between the two. The second side of the first connecting portion and the second side of the second connecting portion can pivot about the bending portion as a pivot axis, thereby moving away from or towards each other.

[0006] In one embodiment, the first hinge unit further includes a first insertion portion, and the second hinge unit further includes a second insertion portion; The first plug-in portion is used to connect to the first part of the water tank, and when the first plug-in portion is connected to the first part, the first side of the first plug-in portion is flush with the surface of the first part. The second connector is used to connect to the second part of the water tank, and when the second connector is connected to the second part, the first side of the second connector is flush with the surface of the second part.

[0007] In one embodiment, the first plug portion is provided with one or more first buckles, which are used to engage with the first portion. The second insertion part is provided with one or more second latches, which are used to engage with the second part.

[0008] In one embodiment, a first inclined surface is further provided on the second side of the first connecting portion, and a second inclined surface is further provided on the second side of the second connecting portion. When the hinge is in the closed state, the first inclined surface and the second inclined surface are arranged opposite to each other to form a pivot groove.

[0009] In one embodiment, the first connecting portion is provided with one of a first connecting hole or a first connecting groove, which is used to cooperate and connect with the other of the first connecting hole or the first connecting groove on the first portion. The second connecting part is provided with one of a second connecting hole or a second connecting groove, which is used to cooperate and connect with the other of the second connecting hole or the second connecting groove on the second part.

[0010] In one embodiment, the hinge is made of a flexible material.

[0011] In one embodiment, the lengths of both the first connecting portion and the second connecting portion are greater than or equal to 5 mm.

[0012] This utility model also provides a water tank for a ventilation device, the water tank having the above-mentioned hinge structure for a ventilation device, wherein the position of the hinge includes any of the following: The top of the water tank; The front of the water tank; The rear of the water tank; and It is located on the same side as the inlet and outlet on the water tank.

[0013] In one embodiment, the water tank is provided with an air passage and a sealing element. The air passage is an integrated silicone corrugated air passage, which includes an air inlet channel and an air outlet channel that are isolated from each other and are respectively connected to the inlet and outlet of the water tank. The sealing element is connected to a first part or a second part of the water tank.

[0014] This utility model also provides a ventilation device, including the above-mentioned water tank hinge structure for ventilation devices, and also includes a main unit and a breathing mask. The main unit is connected to the first gas channel, and the second gas channel is connected to the breathing mask.

[0015] Compared with the prior art, the present invention has the following advantages: Since the hinge includes an integrally set first hinge unit and second hinge unit, the first hinge unit and the second hinge unit can pivot around their connection position to move away from or towards each other to achieve opening and closing. Therefore, the hinge of the present invention does not need to set a rotating part such as a pivot, but rotates by relying on its own connection position, making the structure of the hinge simple and compact and not occupying the internal space of the water tank. On the other hand, by pivoting around its own connection position as the pivot center to achieve opening and closing, its structure is more stable and can avoid damage caused by external impacts such as bumps and drops to the greatest extent.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-19As shown, this utility model provides a water tank hinge structure for a ventilation device, including a hinge member 2 connected to the water tank. The hinge member 2 includes an integrally formed first hinge unit 21 and a second hinge unit 22. The hinge member 2 can be opened or closed to allow the water tank to be opened (e.g., Figure 2 , Figure 3 , Figure 4 and Figure 5 (as shown) or turn off (as shown) Figure 7 and Figure 8 (As shown).

[0021] Among them, when the hinge 2 is in the open state (e.g. Figure 6 and Figure 12 As shown), the first hinge unit 21 and the second hinge unit 22 pivot about their connection position, thus moving away from each other, and the surfaces of the first hinge unit 21 and the second hinge unit 22 at the connection position move away from each other; when the hinge 2 is in the closed state (as shown), Figure 9 and Figure 14 As shown), the first hinge unit 21 and the second hinge unit 22 pivot around their connection position as the pivot axis, thereby moving closer to each other, and the surfaces of the first hinge unit 21 and the second hinge unit 22 move closer to each other at the connection position.

[0022] In some implementations, such as Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the first hinge unit 21 includes a first connecting portion 211, and the second hinge unit 22 includes a second connecting portion 221. The first side of the first connecting portion 211 and the first side of the second connecting portion 221 are connected to each other, and a bend 23 is provided at the connection point. The second side of the first connecting portion 211 and the second side of the second connecting portion 221 can pivot about the bend 23 as a pivot axis, thereby moving away from or towards each other.

[0023] The bending portion 23 can be, for example, a crease, a pivoting groove, etc., so that the first connecting portion 211 and the second connecting portion 221 can pivot at their connection. It can be understood that the first connecting portion 211, the second connecting portion 221 and the bending portion 23 are an integral structure, and the bending portion 23 is a structure with a crease, pivoting groove, etc., pre-set at the connection between the first connecting portion 211 and the second connecting portion 221 to facilitate pivoting.

[0024] like Figure 12As shown, the second side of the first connecting portion 211 (e.g., the side facing the water tank 1) has a first separating surface 2111, and the second side of the second connecting portion 221 (e.g., the side facing the water tank 1) has a second separating surface 2211. The first separating surface 2111 and the second separating surface 2211 move away from each other when the first hinge unit 21 and the second hinge unit 22 pivot relative to each other to the open state, and abut against each other when the first hinge unit 21 and the second hinge unit 22 pivot relative to each other to the open / closed state. Therefore, it can be seen that when it is necessary to open the water tank 1, the first hinge unit 21 and the second hinge unit 22 pivot relative to each other, the first separating surface 2111 and the second separating surface 2211 separate from each other, and the first hinge unit 21 and the second hinge unit 22 open, which allows the water tank 1 to open. When it is necessary to close the water tank 1, the first hinge unit 21 and the second hinge unit 22 pivot relative to each other in opposite directions, and the first separation surface 2111 and the second separation surface 2211 approach each other until they abut against each other, so that the first hinge unit 21 and the second hinge unit 22 close, thereby closing the water tank 1.

[0025] Therefore, the hinge 2 of this utility model does not adopt a structure that achieves opening and closing by setting a pivot and rotating around the pivot. Instead, it pivots on its own bent portion 23. On the one hand, it can eliminate the pivot and other structures in the existing structure, making the structure of the hinge 2 simple and compact. On the other hand, it achieves opening and closing by pivoting around its own bent portion 23 as the pivot center. The bent portion 23, the first hinge unit 21 and the second hinge unit 22 are an integral part, so the structure is more stable and can avoid damage caused by external impacts such as bumps and drops to the greatest extent.

[0026] Furthermore, the first hinge unit 21 and the second hinge unit 22 are respectively engaged and connected to the water tank 1. Specifically, as follows... Figure 1 , Figure 2 and Figure 3 As shown, the water tank includes an openable first part 11 and a second part 12. The first part 11 may be, for example, an upper shell of the water tank, and the second part may be, for example, a lower shell of the water tank.

[0027] like Figure 12 As shown, the first hinge unit 21 further includes a first insertion portion 212, and the second hinge unit 22 further includes a second insertion portion 222. The first connecting portion 211 and the first insertion portion 212 are connected and are substantially perpendicular to each other; similarly, the second connecting portion 221 and the second insertion portion 222 are connected and are substantially perpendicular to each other.

[0028] like Figure 6 and Figure 9As shown, the first connector 212 is used to connect to the first part 11 of the water tank 1, and when the first connector 212 is connected to the first part 11, the first side of the first connector 211 is flush with the surface of the first part 11.

[0029] The second connector 222 is used to connect to the second part 12 of the water tank 1, and when the second connector 222 is connected to the second part 12, the first side of the second connector 221 is flush with the surface of the second part 12.

[0030] That is, the first insertion part 212 and the second insertion part 222 are respectively inserted into the first part 11 and the second part 12 of the water tank 1. Therefore, when the hinge 2 is in the closed state, as Figure 9 As shown, the first connecting part 211 is flush with the outer surface of the first part 11, and the second connecting part 221 is flush with the outer surface of the second part 12. Furthermore, the first connecting part 211 and the second connecting part 221 are located on the same horizontal line. This can be considered as the opening and closing angle of the hinge 2 (or water tank 1). The angle is 0°. Therefore, the water tank 1 has no outward protruding parts. When the water tank 1 is in the closed state, the hinge 2 is almost invisible, achieving its "invisible" function, thus ensuring its aesthetic appearance and preventing damage caused by bumps.

[0031] Furthermore, since the hinge 2 does not have a pivot, but pivots through its own bending portion 23, there is no need to provide space for the pivot or other components on the first part 11 and the second part 12 of the water tank 1 that it cooperates with. Thus, the first insertion portion 212 can be directly inserted into the side wall of the first part 11 of the water tank 1, and the second insertion portion 222 can be inserted into the side wall of the second part 12 of the water tank 1, without occupying the internal space of the water tank 1. Therefore, the hinge 2 will not affect the volume of the water tank 1, and thus will not reduce the actual capacity of the water tank 1, thereby improving the humidification effect of the ventilation equipment.

[0032] like Figure 6 As shown, when the hinge 2 is in the open state, the first hinge unit 21 and the second hinge unit 22 pivot relative to each other, and the opening angle between the first connecting part 211 and the second connecting part 221 is... The distance between the first insertion portion 212 and the second insertion portion 222 increases, thereby putting the water tank 1 in the open state. The maximum degree of relative pivoting between the first hinge unit 21 and the second hinge unit 22 is such that the first side surface of the first connection portion 211 (e.g., the side facing away from the water tank 1) and the first side surface of the second connection portion 221 (e.g., the side facing away from the water tank 1) are almost in contact or mutually in contact, i.e., the opening angle of the hinge 2 (or the water tank 1). The maximum is 180°.

[0033] Therefore, the pivot angle of the first hinge unit 21 and the second hinge unit 22 about their connection position is 1°-180°.

[0034] Furthermore, for ease of manufacturing, the first hinge unit 21 and the second hinge unit 22 can be configured to be symmetrically arranged about their connection positions.

[0035] Please continue to refer to this. Figure 9 and Figure 12 The first insertion part 212 is provided with one or more first buckles 213, which protrude outward from the side wall of the first insertion part 212 and are used to engage with the first part 11; the second insertion part 222 is provided with one or more second buckles 223, which protrude outward from the side wall of the second insertion part 222 and are used to engage with the second part 12.

[0036] Through the interlocking action of the first buckle 213 and the first part 11, and the interlocking action of the second buckle 223 and the second part 12, the hinge 2 can be fixedly connected to the first part 11 and the second part 12 of the water tank 1, ensuring stable opening and closing operation.

[0037] Specifically, please combine Figure 9 , Figure 11A and Figure 11B The first part 11 has a first snap-fit ​​part 111 on its side wall, which includes a first receiving groove 1111 and a first snap-fit ​​groove 1112, which extend in a generally vertical direction and communicate with each other. The second part 12 has a second snap-fit ​​part 121 on its side wall, which includes a second receiving groove 1211 and a second snap-fit ​​groove 1212, which extend in a generally vertical direction and communicate with each other.

[0038] When connecting the hinge 2 and the water tank 1, the first insertion part 212 is inserted into the first receiving groove 1111, and the first latch 213 on it extends into the first latch groove 1112, thereby fixing the first insertion part 212 in the first receiving groove 1111. Similarly, the second insertion part 222 is inserted into the second receiving groove 1211, and the first latch 213 on it extends into the first latch groove 1112, thereby fixing the first insertion part 212 in the first receiving groove 1111. Therefore, as Figure 11B As shown, when the first part 11 and the second part 12 of the water tank 1 are opened, the first plug 212 is fixed to the first part 11 and the second plug 222 is fixed to the second part 12. Therefore, when the first connecting part 211 and the second connecting part 221 pivot relative to each other, the first part 11 and the second part 12 can be pivoted relative to each other to open the tank.

[0039] It is conceivable that the first latch 213 and the second latch 223 can also be elastic latch structures, that is, the first latch 213 can elastically extend or retract relative to the first insertion part 212, and the second insertion part 222 can elastically extend or retract relative to the second insertion part 222. Thus, when the first insertion part 212 is inserted into the first receiving groove 1111, the first latch 213 retracts, so that the first insertion part 212 can be smoothly inserted into the first receiving groove 1111. After insertion is completed, the first latch 213 loses its constraint at the first latch groove 1112 and extends into the first latch groove 1112, thereby fixing the first insertion part 212 in the first receiving groove 1111. Similarly, when the second insertion part 222 is inserted into the second receiving groove 1211, the second latch 223 retracts so that the second insertion part 222 can be smoothly inserted into the second receiving groove 1211. After insertion, the second latch 223 loses its constraint at the second latch groove 1212 and extends into the second latch groove 1212, thereby fixing the second insertion part 222 in the second receiving groove 1211.

[0040] like Figure 14 As shown, in order to facilitate pivoting, a first inclined surface 214 can be provided on the second side of the first connecting part 211, and a second inclined surface 224 can be provided on the second side of the second connecting part 221. When the hinge 2 is in the closed state, the first inclined surface 214 and the second inclined surface 224 are arranged opposite to each other, and a pivoting groove 231 is formed between them.

[0041] The hinge 2 can be located on the top of the water tank 1, the front of the water tank 1, the rear of the water tank 1, or on the same side as the inlet and outlet of the water tank 1.

[0042] like Figure 16 As shown, hinge 2 can be located at the top of water tank 1. The top of water tank 1 is along... Figure 16 The top of the water tank 1 is shown in the Z-axis direction, which is the height direction of the water tank 1. At this time, the first part 11 and the second part 12 of the water tank 1 are structures that open and close vertically.

[0043] like Figure 17 and Figure 18 As shown, hinge 2 can be located on the side of water tank 1. Figure 17 As shown, the hinge is located on the right side of water tank 1; as Figure 18 As shown, the hinge is located on the left side of water tank 1. The side of water tank 1 is along... Figure 17 and Figure 18 The X-axis direction is shown, which is the end of the water tank 1 along its length. At this time, the first part 11 and the second part 12 of the water tank 1 are structures that open and close from left to right.

[0044] like Figure 19 As shown, hinge 2 can be located on the same side as the inlet and outlet of water tank 1. Figure 19As shown, the inlet 13 and outlet 14 of the water tank are located at the front of the water tank 1. The front of the water tank 1 is along... Figure 19 The Y-axis direction shown is the end of the water tank 1 along its width. At this time, the first part 11 and the second part 12 of the water tank 1 have an opening and closing structure.

[0045] like Figure 13 and Figure 15 As shown, the length of the hinge 2, namely the length of the first connecting part 211 (or the first plug-in part 212) and the second connecting part 221 (or the second plug-in part 222), is greater than or equal to 5mm to ensure the connection strength with the water tank 1.

[0046] Hinge 2 can be made of flexible materials, such as PP (polypropylene), PPSU (amorphous thermoplastic), or silicone. Flexible materials allow for smoother transitions between open and closed states and also ensure a longer service life, preventing fatigue failure due to repeated opening and closing.

[0047] like Figure 2 As shown, a connecting buckle 112 can also be provided on the first part 11 of the water tank 1, which is used to fasten and connect with the second part 12 to ensure that the two can be stably closed.

[0048] like Figures 20-21 As shown, compared with the various embodiments described above, the length of the hinge 2 can be longer, so more of the first buckle 213 and the second buckle 223 can be provided.

[0049] like Figure 20 and Figure 21 As shown, there can be multiple first buckles 213 and second buckles 223. Multiple first buckles 213 can be spaced apart along the length direction of the first insertion part 212, and second buckles 223 can be spaced apart along the length direction of the second insertion part 222, so as to meet the opening and closing requirements of a larger water tank 1.

[0050] In addition, the number of hinge 2 can be referenced. Figure 2 Multiple settings are shown ( Figure 2 (The diagram shows that there are two hinges 2). Understandably, more hinges 2 can be provided as needed.

[0051] like Figures 22-31 As shown, compared with the aforementioned embodiments, the hinge 2 and the water tank 1 can also be configured to be connected without a snap fastener, that is, the first plug-in part 212 and the second plug-in part 222 can be omitted.

[0052] Specifically, the first connecting part 211 is provided with one of a first connecting hole or a first connecting groove, which is used to cooperate and connect with the other of the first connecting hole or the first connecting groove on the first part 11; the second connecting part 221 is provided with one of a second connecting hole or a second connecting groove, which is used to cooperate and connect with the other of the second connecting hole or the second connecting groove on the second part.

[0053] like Figure 22 , Figure 24 , Figure 28 , Figure 29 and Figure 30 In the example shown, a first connecting hole 215 is provided on the first connecting part 211, and a first connecting post 113 is provided on the first part 11; as shown Figure 22 , Figure 23 , Figure 28 , Figure 29 and Figure 30 In the example shown, a second connecting portion 221 is provided with a second connecting hole 225, and a second connecting post 123 is correspondingly provided on the second portion 12. There may be multiple first connecting holes 215, which can extend along the length direction of the first connecting portion 211; there may also be multiple second connecting holes 225, which can extend along the length direction of the second connecting portion 221.

[0054] Furthermore, the engagement of the first connecting hole 215 and the first connecting post 113 can be achieved by causing elastic deformation of the first connecting hole 215. Since the hinge 2 is made of a flexible material, the inner diameter of the first connecting hole 215 can be set smaller than the diameter of the first connecting post 113. Therefore, when the first connecting hole 215 is fitted onto the first connecting post 113, the first connecting hole 215 can undergo slight deformation to fit onto the first connecting post 113. After the two are connected, the first connecting hole 215 returns to its original shape and will not detach from the first connecting post 113. Alternatively, a top cover can be provided at the top of the first connecting post 113 to prevent the first connecting hole 215 from detaching from the first connecting post 113. Understandably, the engagement of the second connecting hole 225 and the second connecting post 123 is similar to the engagement of the first connecting hole 215 and the first connecting post 113.

[0055] like Figure 31 As shown, corresponding grooves 15 can be provided on the first part 11 and the second part 12 of the water tank 1 to respectively accommodate the first connecting part 211 and the second connecting part 221; please refer to Figure 25 , Figure 26 and Figure 27This allows the first connecting part 211 to be flush with the outer surface of the first part 11, and the second connecting part 221 to be flush with the outer surface of the second part 12. Therefore, the water tank 1 as a whole has no outwardly protruding parts, and when the water tank 1 is in the closed state, the hinge 2 is almost invisible, achieving its "invisible" function, thereby ensuring its aesthetic appearance and preventing damage caused by bumps.

[0056] In addition, in order to ensure that the first connecting part 211 and the second connecting part 221 can be opened and closed smoothly, similar to the above embodiment, a pivot folding groove 231 can be provided at the connection between the first connecting part 211 and the second connecting part 221 to ensure smooth opening and closing.

[0057] In addition, the connection holes and connection slots can be used to make the structure of the hinge 2 simpler and the connection and fixation more convenient.

[0058] This utility model also provides a water tank for a ventilation device, including the water tank hinge structure for a ventilation device described in the above embodiments, and further including a water tank 1, as shown in the figure. Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the hinge 2 is located on the top of the water tank 1, the front of the water tank 1, the rear of the water tank 1, or on the same side as the inlet and outlet of the water tank 1.

[0059] In addition, the ventilation equipment also includes a main unit connected to the inlet 13 of the water tank 1 and a breathing mask connected to the outlet 14 of the water tank 1. The specific implementation of the main unit and the breathing mask, as well as the connection method with the water tank 1, can adopt various existing implementation methods and connection methods, which will not be elaborated in this utility model.

[0060] like Figure 32 and Figure 1 As shown, the water tank 1 is equipped with an air passage 3, which is an integrated silicone corrugated air passage. It includes an isolated inlet channel 31 and an outlet channel 32, which are connected to the inlet 13 and outlet 14 of the water tank 1, respectively. Furthermore, the inlet channel 31 and outlet channel 32 each have separate openings for communication with the interior of the water tank 1. Therefore, pressurized gas from the main unit can enter the inlet channel 31 through the inlet 13 of the water tank 1, and then enter the interior of the water tank 1 through the opening in the inlet channel 31 for heating, humidification, and other operations. The heated and humidified gas then enters the outlet channel 32 through the opening in the outlet channel 32, and is output to the breathing mask through the outlet 14 of the water tank 1 for patient breathing. The integrated silicone corrugated air passage ensures smooth gas flow and enhances the overall sealing of the water tank 1, preventing gas leakage.

[0061] In addition, such as Figure 32 As shown, a removable seal 16 is also provided in the water tank 1 on the first part 11 or the second part 12. The seal 16 can be located, for example, on the upper end of the second part 12 along its entire circumference, so as not to occupy the water tank volume and to facilitate disassembly and replacement, thereby improving the patient's user experience and reducing the cost of use. In addition, the seal 16 can also be connected to the air passage 3 or the two can be integrated into one unit.

[0062] It should be noted that the water tank and breathing mask of this utility model can adopt various structural forms known in the prior art, and the connection between them and the water tank 1 can also adopt various structural forms known in the prior art. Those skilled in the art can know the specific structure and implementation principle of the host and breathing mask in the prior art, and can freely combine them with the water tank of this utility model without any technical obstacles.

[0063] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
