Fig. 7 and Fig. 8 is shown according to some embodiments of the disclosure for being pacified liquid chamber by retaining mechanism Example process in main body.As shown in fig. 7, liquid chamber 1704 can be driven and be subsequently fitted to by the first thrust In main body 1702.In some embodiments, the first thrust can be generated by user.First pushing direction can be by arrow A Instruction (such as vertical direction, also referred to as second direction).In some embodiments, push rod 1906 can pass through the first hole 1709 And it interacts with bootstrap block 2005.In some embodiments, in its relaxed state, the center of push rod 1906 can be with It is located at the right side of the bottom of the second protrusion 2075 along first direction.When being driven by the first thrust, push rod 1906 can be with liquid Fluid chamber 1704 together in a second direction (being indicated from arrow A) it is mobile and along the first inclined-plane 2015 of bootstrap block 2005 to downslide It is dynamic, and therefore, when push rod 1906 moves down, push rod 1906 can push bootstrap block 2005 along first direction (arrow B Instruction) it is mobile, and second spring 2008 can be compressed.Meanwhile the second spring 2008 of compression can produce reaction force, it should Reaction force is for making push rod 1906 be guided the pressing of block 2005.In some embodiments, first direction can be substantially vertical In second direction.In some embodiments, if the first thrust is greater than reaction force, push rod 1906 can be along third inclined-plane 2055 slide downwards and be moved to or close to third inclined-plane 2055 feather edge.Then, push rod 1906 can with the first inclined-plane and/ Or third inclined-plane 2055 separates, and can reach the bottom part down of the first protrusion 2065.

In some embodiments, if the first thrust is released, push rod 1906 can be along opposite with second direction Direction it is mobile, and push rod 1906 can be on the left side in the region formed by the protrusion 2045 and groove 2035 of bootstrap block 2005 It is slided in side section.Meanwhile bootstrap block 2005 can opposite direction along a first direction it is mobile.When push rod 1906 be moved to it is recessed When the top position of slot 2035, push rod 1906 and bootstrap block 2005 can stop moving, and therefore, guidance can be inserted in push rod 1906 (referring to Fig. 8) in the groove 2035 of block 2005.Therefore, liquid chamber 1704 may be mounted in main body 1702.In some realities It applies in mode, is mounted in main body 1702 when the first thrust is applied on liquid chamber 1704, and/or in liquid chamber 1704 When, heating plate 1710 can be pressed by the bottom surface of liquid chamber 1704, and can be moved down in the second hole 1711.One In a little embodiments, one or more springs 2202 positioned at 1710 lower section of heating plate can be pressed, fluid chamber is then within The heating plate 1710 and heat-conducting plate 1810 of 1704 bottom of room can form close contact (or close contact).

Fig. 9 and Figure 10, which is shown, removes fluid chamber from main body using the retaining mechanism of some embodiments according to the disclosure The example process of room.As shown in figure 9, liquid chamber 1704 can be driven by the second thrust, then discharged from main body 1702. In some embodiments, the second thrust can be generated by user (such as object 180).Second pushing direction can be by arrow A instruction (such as vertical direction, also referred to as second direction).When being driven by the second thrust, push rod 1906 can be with fluid chamber (being indicated by arrow A) is mobile and in 2035 shape of protrusion 2045 and groove by bootstrap block 2005 in a second direction together for room 1704 At region right part in move down.Meanwhile bootstrap block 2005 can be moved along the opposite direction of first direction (by Arrow B' instruction).In some embodiments, bootstrap block 2005 can be by the second bullet along the moving for opposite direction of first direction The reaction force of spring 2008 drives.Then, push rod 1906 can discharge from groove 2035 and can reach the second protrusion 2075 bottom part down.

In some embodiments, if the second thrust of release, one or more compressions of 1710 lower section of heating plate Spring 2202 heating plate 1710 can be driven to move along the opposite direction of second direction.The movement of heating plate 1710 can be with Driving liquid chamber 1704 is moved along the opposite direction of second direction, and the movement of liquid chamber 1704 can to draw Push rod 1906 is led to move along the opposite direction of second direction.Then, push rod 1906 can along bootstrap block 2005 second tiltedly Face is mobile, and bootstrap block 2005 can opposite direction (being indicated by arrow B') along a first direction it is mobile.Therefore, fluid chamber Room 1704 can discharge (referring to Figure 10) from the main body 1702 of ventilation therapy equipment 1700, and liquid chamber 1704 can be from Main body 1702 removes.

It should be noted that the foregoing description of retaining mechanism 1904 provides for illustration purposes only, it is no intended to which limitation is originally Scope of disclosure.For those of ordinary skill in the art, can be made various changes and modifications under the introduction of the disclosure.So And these change and modification do not depart from the scope of the present disclosure.

In some embodiments, retaining mechanism 1904 can be mounted in different directions in main body 1702, therefore can Different thrust can be needed to remove liquid chamber 1704 to install liquid chamber 1704 and/or install from main body 1702.Some In embodiment, bootstrap block 2005 be can be set to and 2005 mirror symmetry of bootstrap block shown in Fig. 5-Figure 10.In some realities It applies in mode, retaining mechanism 1904 may include more than one push rod.In some embodiments, retaining mechanism 1904 can be with For unlocking liquid chamber 1704 from the main body of ventilation therapy equipment 110 and pushing liquid chamber 1704 along pushing direction. Pushing direction may be substantially perpendicular to the liquid level in liquid chamber 1704.

In some embodiments, retaining mechanism 1904 can be used for forming energy storage device, the energy storage device For storing the energy of pushing action and for by applying the opposite direction substantially along pushing direction on liquid chamber Power stored energy is discharged after liquid chamber 1704 to unlock.It should be noted that in some embodiments, fluid chamber The case lid of room 1704 can be set to close and pushing along pushing direction.In some embodiments, liquid chamber 1704 case lid can be set to open by pulling along direction substantially opposite with pushing direction.

In some embodiments, in the operation of ventilation therapy equipment 110, user can be by pushing along pushing direction Liquid chamber 1704 and the main body that liquid chamber 1704 is connected to ventilation therapy equipment 110, and/or by substantially along pushing Direction pushes liquid chamber 1704 and unlocks liquid chamber 1704 and true main body.In some embodiments, connected Before connecing operation, liquid chamber 1704 can be placed on the surface of ventilation therapy equipment 110 by user.In some embodiments In, the attended operation of liquid chamber 1704 may include that will implement case lid and case and substantially pushing case lid along pushing direction Body locking.

In one embodiment, main body has gas outlet, and liquid chamber has air inlet, is locked to master in liquid chamber When body, gas outlet is connected to air inlet；When liquid chamber and main body unlock, gas outlet and air inlet are disconnected.
