[0040] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0041] This application discloses a connection structure for a breathing mask. The connection structure is connected to the mask body 101 and the fixing component 103 respectively, and the connection structure connects the mask body 101 and the fixing component 103.

[0042] Reference Figures 1 to 10 As shown, the connection structure includes a first connection component 110 and a second connection component 120. The first connection component 110 and the second connection component 120 have a magnetic attraction state and a non-magnetic state. In the magnetic attraction state, the first connection component 110 and the second connection component 120 move towards each other to connect. In the non-magnetic state, the first connection component 110 and the second connection component 120 remain connected.

[0043] In the connection structure of this embodiment, the first connecting component 110 and the second connecting component 120 are in a magnetic attraction state. In this magnetic attraction state, the first connecting component 110 and the second connecting component 120 move towards each other to connect. Connecting via magnetic attraction has the advantage of being effortless. Furthermore, the first connecting component 110 and the second connecting component 120 also have a non-magnetic state. After the first connecting component 110 and the second connecting component 120 move towards each other to connect, they remain in a non-magnetic state, maintaining the connection to ensure the connection between the mask body 101 and the fixing component 103. Maintaining the connection in the non-magnetic state prevents interference from magnetism if it gets too close to certain medical implants or devices in the user's body, which could damage their function, affect the user's health, or even harm the user.

[0044] In some embodiments, the first connecting component 110 includes a component housing 113, a first mounting cavity 1131 is provided within the component housing 113, and a second connecting component 120 is disposed within the first mounting cavity 1131. In the above structure of the embodiments of this application, the second connecting component 120 is disposed within the first mounting cavity 1131 of the first connecting component 110 to avoid adverse effects from external factors on the relative movement of the first connecting component 110 and the second connecting component 120.

[0045] In some embodiments, the component housing 113 is provided with a second mounting cavity. Along the axial direction of the component housing 113, the second mounting cavity is located on the side of the first mounting cavity 1131 away from the second connecting component 120. A first electromagnet 112 is disposed in the second mounting cavity. The second connecting component 120 includes a second magnetic element 123. When the first electromagnet 112 is energized, the first connecting component 110 and the second connecting component 120 are in a magnetic attraction state.

[0046] The first electromagnet 112 is a device that generates electromagnetic fields when energized. When the first electromagnet 112 is energized, the first electromagnet 112 and the second magnetic element 123 attract each other, and the first connecting assembly 110 and the second connecting assembly 120 are in a magnetic attraction state, and the first connecting assembly 110 and the second connecting assembly 120 move towards each other. When the first electromagnet 112 is de-energized, the first electromagnet 112 and the second magnetic element 123 do not attract each other, and the first connecting assembly 110 and the second connecting assembly 120 are in a non-magnetic state.

[0047] The second magnetic element 123 is a magnet (e.g., a permanent magnet) or a metal or other materials that can be magnetically attracted. When the material of the second magnetic element 123 is a magnet, the end of the second magnetic element 123 near the first electromagnet 112 should have opposite magnetism to the end of the first electromagnet 112 near the second magnetic element 123, thereby achieving the magnetic attraction function.

[0048] In this embodiment, the first electromagnet 112 and the second magnetic element 123 are used to achieve the magnetic attraction state and the non-magnetic state, which has the advantages of simplicity and convenience.

[0049] In some embodiments, the first electromagnet 112 includes a coil 1125, a power supply element 1121, and a switching element 1123. The power supply element 1121, the switching element 1123, and the coil 1125 are connected to form a circuit. At least a portion of the switching element 1123 is disposed on the outer surface of the component housing 113 to connect the circuit by touch or pressing.

[0050] The coil 1125 can be formed by winding wire. For example, in one specific embodiment, the wire is connected to the power supply element 1121 and the switching element 1123 in sequence, and wound to form the coil 1125. The form of the power supply element 1121 includes, but is not limited to, at least one of a secondary battery, a dry cell battery, and an external power source.

[0051] It is understood that the switching element 1123 can be a single component, and the circuit can be connected by touching or pressing the switching element 1123. The switching element 1123 may also include a circuit switch and a push-button switch. The circuit switch is set in the circuit, and the circuit switch and the push-button switch work together. When the push-button switch is pressed, the circuit switch closes to connect the circuit.

[0052] Furthermore, refer to Figure 7 As shown, according to Ampere's law, coil 1125 generates a magnetic field, with its N pole being close to one end of the second magnetic element 123, and the magnetic pole of the end of the second magnetic element 123 close to coil 1125 should be the S pole.

[0053] In some embodiments, in order to increase the magnetic field strength of the first electromagnet 112, the first electromagnet 112 is further provided with a metal core 1124, and a coil 1125 is wound on the metal core 1124.

[0054] In some embodiments, the cavity sidewall of the first mounting cavity 1131 is provided with a guide groove 111; the second connecting assembly 120 includes a second magnetic element 123, and the sidewall of the second magnetic element 123 is provided with a guide protrusion 124; in the magnetic attraction state, the guide protrusion 124 moves within the guide groove 111.

[0055] In this embodiment, the guide groove 111 and the guide protrusion 124 are provided so that, in the magnetic attraction state, the guide protrusion 124 moves within the guide groove 111, restricting the movement trajectory between the component housing 113 and the second magnetic element 123, thereby ensuring precise movement between the first connecting component 110 and the second connecting component 120.

[0056] In some embodiments, the second connecting component 120 further includes a locking structure connected to the second magnetic element 123; in a non-magnetic state, the locking structure locks the first connecting component 110 and the second connecting component 120 to remain connected. The locking structure in this embodiment enables the first connecting component 110 and the second connecting component 120 to remain connected, making the connecting structure less prone to detachment.

[0057] In some embodiments, the guide groove 111 has a wave-shaped structure around the axis of the component housing 113, with wave crests and troughs; the locking structure includes a rotating element 126 and an elastic element 125, the rotating element 126 being rotatably connected to the mask body 101, one end of the elastic element 125 being connected to the rotating element 126, and the other end of the elastic element 125 being connected to the second magnetic element 123; in the magnetic attraction state, the first electromagnet 112 attracts the second magnetic element 123, the first connecting assembly 110 and the second connecting assembly 120 move toward each other, and the guide protrusion 124 moves to the wave crest; in the non-magnetic state, the elastic element 125 pulls the second magnetic element 123 away from the first electromagnet 112, the first connecting assembly 110 and the second connecting assembly 120 move away from each other, and the guide protrusion 124 moves to the wave trough.

[0058] One end of the elastic element 125 is connected to the rotating element 126, and the other end of the elastic element 125 is connected to the second magnetic element 123. In the magnetic attraction state, the first electromagnet 112 and the second magnetic element 123 move towards each other, and the elastic element 125 stores force. In the non-magnetic state, the first electromagnet 112 and the second magnetic element 123 no longer attract each other, and the elastic element 125 returns to its initial state to pull the second magnetic element 123 away from the first electromagnet 112 until it moves to the trough 1115.

[0059] Understandably, the crest is farther away from the second connecting component 120 relative to the trough 1115. As the first connecting component 110 and the second connecting component 120 move toward each other, the guide protrusion 124 moves to the crest; and as the first connecting component 110 and the second connecting component 120 move away from each other, the guide protrusion 124 moves to the trough 1115.

[0060] Since the guide groove 111 has a wave-shaped structure around the axis of the component housing 113, the second magnetic element 123 will rotate around the axis of the component housing 113 as the guide protrusion 124 moves along the guide groove 111. The rotation element 126 can be adapted to the rotation of the second magnetic element 123.

[0061] In some embodiments, the guide groove 111 has a plurality of repeating units and a plurality of first grooves 1111; around the axis of the component housing 113, the plurality of repeating units are arranged sequentially, each repeating unit is connected to an adjacent repeating unit, each repeating unit has a crest and a trough, and each is adapted to be provided with a guide protrusion 124; one end of the first groove 1111 is located on the end face of the component housing 113, and the other end of the first groove 1111 is connected to the connection of two adjacent repeating units, and the first groove 1111 is used to guide the protrusion 124 to move into or out of the repeating unit.

[0062] In this embodiment, any repeating unit is provided with a guide protrusion 124 that moves within it.

[0063] One or more guide protrusions 124 are provided on the sidewall of the second magnetic element 123. The number of guide protrusions 124 may be less than the number of repeating units or equal to the number of repeating units. When the number of guide protrusions 124 is less than the number of repeating units, the number of repeating units may be a multiple of the number of guide protrusions 124.

[0064] The first groove 1111 is used to guide the protrusion 124 into the repeating unit to achieve assembly; the first groove 1111 is also used to guide the protrusion 124 out of the repeating unit to achieve disassembly.

[0065] In some embodiments, the repeating unit includes a second slot 1112, a third slot 1114, a fourth slot 1116, and a fifth slot 1118, which are connected sequentially. The connection between the second slot 1112 and the third slot 1114 is a first peak 1113, the connection between the third slot 1114 and the fourth slot 1116 is a trough 1115, and the connection between the fourth slot 1116 and the fifth slot 1118 is a second peak 1117. The second slot 1112 is located away from the third slot 1114. The end of the fifth groove 1118 is connected to the first groove 1111, and the end of the fifth groove 1118 that is away from the fourth groove 1116 is connected to the first groove 1111. In the magnetic attraction state, the guide protrusion 124 moves to the first peak 1113 in the second groove 1112 or the third groove 1114, or moves to the second peak 1117 in the fourth groove 1116 or the fifth groove 1118. In the non-magnetic state, the guide protrusion 124 moves to the trough 1115 in the third groove 1114 or the fourth groove 1116, or moves towards the first groove 1111 in the second groove 1112 or the fifth groove 1118.

[0066] In the magnetic attraction state, the first connecting component 110 and the second connecting component 120 move towards each other; in the non-magnetic state, the first connecting component 110 and the second connecting component 120 move away from each other. Therefore, the first peak 1113 and the second peak 1117 move away from the mask body 101 relative to the trough 1115.

[0067] During the connection process of the first connecting component 110 and the second connecting component 120, the guide protrusion 124 can enter the second segment groove 1112 through the first segment groove 1111, and then sequentially exit from the other first segment groove 1111 through the second segment groove 1112, the third segment groove 1114, the fourth segment groove 1116, and the fifth segment groove 1118. Alternatively, the guide protrusion 124 can enter the fifth segment groove 1118 through the first segment groove 1111, and then sequentially exit from the other first segment groove 1111 through the fourth segment groove 1116, the third segment groove 1114, and the second segment groove 1112. In the above structure of this embodiment, during the installation process between the first connecting component 110 and the second connecting component 120, the guide protrusion 124 can be aligned with either first segment groove 1111 to achieve installation, facilitating the installation between the first connecting component 110 and the second connecting component 120.

[0068] In some embodiments, the second groove 1112, the third groove 1114, the fourth groove 1116, and the fifth groove 1118 are sequentially connected. In the above structure of this application embodiment, the second groove 1112, the third groove 1114, the fourth groove 1116, and the fifth groove 1118 are unidirectional moving grooves. The guide protrusion 124 can only move unidirectionally along the second groove 1112, the third groove 1114, the fourth groove 1116, and the fifth groove 1118, and cannot move in the opposite direction. That is, when the elastic member 125 pulls the second magnetic element 123, the guide protrusion 124 located at the first wave crest 1113 will directly enter the third groove 1114 after emerging from the first wave crest 1113, and will not enter the second groove 1112. Correspondingly, in the magnetic attraction state, the guide protrusion 124 located at the trough 1115 will directly enter the fourth groove 1116, and will not enter the third groove 1114. The guide protrusion 124 located at the second wave peak 1117 will directly enter the fifth groove 1118, instead of the fourth groove 1116.

[0069] Further reference Figure 6 As shown, the first peak 1113 faces the third groove 1114, and the guide protrusion 124 located on the first peak 1113 will directly enter the third groove 1114 after exiting the first peak 1113. The trough 1115 faces the fourth groove 1116, and the guide protrusion 124 located on the trough 1115 will directly enter the fourth groove 1116. The second peak 1117 faces the fifth groove 1118, and the guide protrusion 124 located on the second peak 1117 will directly enter the fifth groove 1118. The positions of the first peak 1113, the second peak 1117, and the trough 1115 allow the guide protrusion 124 to move unidirectionally within the second groove 1112, the third groove 1114, the fourth groove 1116, and the fifth groove 1118.

[0070] In some embodiments, the first slot 1111 is a straight slot or a curved slot; and / or, the second slot 1112 is a straight slot or a curved slot; and / or, the third slot 1114 is a straight slot or a curved slot; and / or, the fourth slot 1116 is a straight slot or a curved slot; and / or, the fifth slot 1118 is a straight slot or a curved slot. The shapes of the first slot 1111, second slot 1112, third slot 1114, fourth slot 1116, and fifth slot 1118 in this application embodiment are set according to usage requirements, and this application embodiment does not specifically limit them. (Refer to...) Figure 6 As shown, the first groove 1111, the second groove 1112, the third groove 1114, the fourth groove 1116 and the fifth groove 1118 are all straight groove segments.

[0071] In some embodiments, the second groove 1112 and the fourth groove 1116 have the same shape, and the third groove 1114 and the fifth groove 1118 have the same shape to facilitate processing.

[0072] Understandably, the tilt angle can also be set according to usage requirements. For example, the tilt angle of the second groove 1112 is greater than the tilt angle of the third groove 1114.

[0073] In some embodiments, the second connecting assembly 120 further includes a limiting rod 122 and a blocking member 121, which is perpendicular to the limiting rod 122. The cross-sectional area of ​​the blocking member 121 is larger than that of the limiting rod 122. One end of the limiting rod 122 is used to connect to the mask body 101, and the other end of the limiting rod 122 is connected to the blocking member 121. A second magnetic element 123 is sleeved on the limiting rod 122, and a rotating element 126 is arranged around the limiting rod 122.

[0074] In this embodiment, the blocking member 121 can be used to block the second magnetic element 123 to prevent the second magnetic element 123 from coming off the limiting rod 122.

[0075] The limiting rod 122 of the first connecting component 110 and the mask body 101 can be connected by integral molding or by mechanical structure, such as by a rope hole.

[0076] In this embodiment, the second magnetic element 123 is fixed by the limiting rod 122 and the elastic member 125, and is limited by the blocking member 121, so that it can only rotate or move up and down around the limiting rod 122. The second magnetic element 123 is connected to the elastic member 125 and the limiting rod 122 respectively, and the second magnetic element 123, the elastic member 125, and the rotating element 126 rotate together around the limiting rod 122. The axis of the limiting rod 122 coincides with the axis of the component housing 113.

[0077] In some embodiments, the first connecting component 110 includes a first electromagnet 112, and the second connecting component 120 includes a second electromagnet or a second magnetic element 123; or, the first connecting component 110 includes a first electromagnet 112 or a first magnetic element, and the second connecting component 120 includes a second electromagnet. That is, the connection structure of this application embodiment can be configured such that one of the first connecting component 110 and the second connecting component 120 is an electromagnet, and the other includes a magnetic element, so that when the first connecting component 110 and the second connecting component 120 need to be connected, they are in a magnetic attraction state, and after the first connecting component 110 and the second connecting component 120 are connected, they are in a non-magnetic state. This avoids interference from magnetism when it is too close to certain medical implants or devices in the user's body, thereby damaging their function, affecting the user's health, or even endangering the user.

[0078] In some embodiments, the materials of the first connecting component 110 and the second connecting component 120 are set according to usage requirements. For example, the component housing 113 of the first connecting component 110 and the blocking member 121, limiting rod 122, rotating element 126, etc. of the second connecting component 120 are made of relatively hard materials such as PP (polypropylene) and PC (polycarbonate), and relatively soft materials such as silicone, foam, gel, and fabric can also be used. Two or more materials can also be used in combination, for example, but not limited to using hard materials for the mating parts and soft materials for the parts away from the user end. Molding methods include, but are not limited to, injection molding, cutting, or 3D printing.

[0079] In some embodiments, a specific connection process of the connection structure is as follows:

[0080] like Figure 6 and Figure 11 As shown, when the first electromagnet 112 of the first connecting assembly 110 is energized and generates magnetism, the second magnetic element 123 of the second connecting assembly 120 drives the guide protrusion 124 to move upward along the limiting rod 122, so that the guide protrusion 124 enters the repeating unit from the first groove 1111.

[0081] Under the influence of magnetic attraction, the guide protrusion 124 rises along the second groove 1112 and enters the first peak 1113. Since the magnetic attraction is always present, the guide protrusion 124 will maintain this state. During this process, the elastic element 125 also stretches under the magnetic attraction, thereby accumulating elastic potential energy. When the second magnetic element 123 is de-energized and loses its magnetism, it will descend along the third groove 1114 under the elastic force of the elastic element 125 and enter the trough 1115. The first connecting assembly 110 and the second connecting assembly 120 are then assembled.

[0082] like Figure 6 and Figure 12 As shown, when the first electromagnet 112 of the first connecting assembly 110 is energized again and generates magnetism, the second magnetic element 123 and the guide protrusion 124 rise along the fourth groove 1116 under the action of magnetic attraction, entering the second peak 1117. Since the magnetic attraction is always present, the guide protrusion 124 will continue to maintain this state. During this process, the elastic element 125 is also stretched again under the action of magnetic attraction, thereby accumulating elastic potential energy again. When the first electromagnet 112 is de-energized again and loses its magnetism, the guide protrusion 124 will descend along the fifth groove 1118 under the action of the elastic force of the elastic element 125, leaving the guide groove 111 from the first groove 1111 connected to the fifth groove 1118. The first connecting assembly 110 and the second connecting assembly 120 are then disassembled.

[0083] During the assembly and disassembly of the first connecting component 110 and the second connecting component 120 of the connecting structure, the guide protrusion 124 moves along the guide groove 111, causing the second magnetic element 123 to undergo lateral displacement, that is, to rotate around the limiting rod 122, thereby causing the elastic element 125 and the rotating element 126 to rotate together around the limiting rod 122.

[0084] The connection structure of this application embodiment generates a magnetic field only during assembly and disassembly, and does not have magnetic force before and after assembly and disassembly. It does not have a continuous magnetic field, thereby reducing the harm of the magnetic field to the user.

[0085] This application embodiment also provides a breathing mask 100, which includes a mask body 101, a fixing component 103 and a connecting structure. The connecting structure is connected to the mask body 101 and the fixing component 103 respectively, and the connecting structure is as described above.

[0086] The mask body 101 includes a support housing 104 and a sealing element 102. The sealing element 102 is provided around the outer periphery of the support housing 104. The support housing 104 is connected to a connecting structure. The sealing element 102 contacts the user's face and is used to seal the contact area between the mask body 101 and the user's face; moreover, the sealing element 102 is relatively soft, which can increase comfort.

[0087] In this embodiment, the breathing mask 100 includes a mask body 101, a fixing component 103, a first connecting component 110, and a second connecting component 120. (Refer to...) Figure 1 As shown, the two ends of the fixing component 103 are respectively connected to the first connecting component 110, and the mask body 101 is respectively connected to two second connecting components 120. The first connecting component 110 and the second connecting component 120 are connected to connect the mask body 101 and the fixing component 103.

[0088] The breathing mask 100 of this application embodiment can be applied in a ventilation therapy device. In this case, the ventilation therapy device includes a ventilator and the breathing mask described above. The ventilator is connected to the breathing mask and is used to input gas into the breathing mask.

[0089] It should be noted that the connecting structure and the breathing mask can be referenced to each other and have the same or similar beneficial effects as any of the aforementioned connecting structures. To avoid repetition, they will not be described again here.
