It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0034] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0035] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] Such as Figures 1 to 6As shown in the figure, the utility model discloses a ventilator with a quick-installation water tank, which includes a machine body 100 and a water tank 200. Among them, the machine body 100 includes an installation platform 110, a limiting member 120 and an energy supply module 130. An energy supply port is provided on the installation platform 110, and the energy supply module 130 is embedded in the energy supply port. An arc-shaped guiding portion 111 is further provided on the installation platform 110, and the center of the arc is set on the axis of the energy supply module 130, which can ensure that the water tank 200 is docked in place; the limiting member 120 is arranged relative to the opening direction of the guiding portion 111, and part of the limiting member 120 can selectively protrude from the installation platform 110; the water tank 200 includes a box body 210 and a heating module 220 for heating the standard water contained in the box body 210. The box body 210 is provided with a matching portion 211 and a limiting portion 212, and the matching portion 211 is detachably connected to the guiding portion 111; the water tank 200 is placed on the installation platform 110, and the water tank 200 is pushed towards the opening range of the guiding portion 111. The matching portion 211 is automatically aligned and connected with the guiding portion 111, the heating module 220 is coaxially attached to the energy supply module 130, and at the same time the limiting portion 212 abuts against the limiting member 120, ensuring the stability of the installation of the water tank 200, preventing the water tank 200 from sliding out, and being able to quickly and stably complete the installation of the water tank 200. The structure is simple, the degree of freedom of the operating space is high, it can automatically correct the installation guiding track, and there is no need to deliberately calibrate the docking. The installation is convenient and firm. It can be understood that the arc-shaped guiding portion 111 is a minor arc less than a semi-circle, with a large enough opening range to facilitate the disassembly and installation of the water tank 200. The water tank 200 can be docked from multiple angles. Only by applying a thrust along the general direction of the opening of the guiding portion 111, there will be a centripetal component force for aligning the heating module 220 with the energy supply module 130. Eventually, the water tank 200 will be automatically limited and guided to the specified position through the arc-shaped guiding portion 111 to complete the docking installation, achieving the effect of "reaching the same goal by different routes", reducing the calibration and docking difficulty required for installation, further facilitating the patient to assemble and use by themselves, and being able to reduce the installation difficulty and speed up the treatment process in different scenarios.

[0037] In this embodiment, the body 100 includes a control member 140. The control member 140 is fixedly connected to the limiting member 120. A control track is provided on the installation platform 110. Part of the control member 140 protrudes from the installation platform 110. The control member 140 is slidably connected to the control track. The control member 140 is used to control some of the limiting members 120 to selectively protrude from the installation platform 110. When the water tank 200 needs to be disassembled, the control member 140 is slid to drive the limiting member 120 to retract, not higher than the installation platform 110 at all. The limiting portion 212 of the box body 210 is no longer hindered by the limiting member 120 and is force-braked. The water tank 200 can slide out flexibly, and at the same time, the matching portion 211 and the guiding portion 111 are disassembled; when the water tank 200 needs to be installed, the water tank 200 is pushed so that the matching portion 211 is docked with the guiding portion 111, and then the control member 140 is slid in the reverse direction, and some of the limiting members 120 protrude from the installation platform 110 again, making contact with the limiting portion 212 to prevent the water tank 200 from slipping.

[0038] Further, a first guiding inclined surface 121 is provided at one end of the limiting member 120 away from the guiding portion 111. The first guiding inclined surface 121 is arranged at an angle with the opening direction. A second guiding inclined surface 2121 is provided at one end of the limiting portion 212 close to the matching portion 211. The second guiding inclined surface 2121 can slide relative to the first guiding inclined surface 121 so that the limiting member 120 retracts into the installation platform 110. When the water tank 200 needs to be installed, the second guiding inclined surface 2121 of the limiting portion 212 first contacts the end of the limiting member 120 away from the guiding portion 111. The first guiding inclined surface 121 can give a second implementation method other than the sliding control member 140 to move the limiting member 120, that is, the second guiding inclined surface 2121 abuts against the first guiding inclined surface 121 and is gradually fed. The water tank 200 moves towards the specified installation position, and the limiting portion 212 presses the limiting member 120 into the installation platform 110 until the limiting member 120 can no longer block the movement of the limiting portion 212. After the installation is in place, the control member 140 drives the limiting member 120 to reset. A first limiting surface 122 is provided at one end of the limiting member 120 close to the guiding portion 111. The first limiting surface 122 is arranged perpendicular to the opening direction. A second limiting surface 2122 is provided at one end of the limiting portion 212 away from the matching portion 211. The second limiting surface 2122 is also perpendicular to the opening direction. The second limiting surface 2122 and the first limiting surface 122 can abut against each other and are arranged in parallel, effectively avoiding the generation of a component force that causes the limiting member 120 to move downward and retract, preventing the water tank 200 from slipping off the installation platform 110 along the opening direction, and further stabilizing the installation state and effect of the water tank 200.

[0039] Preferably, the body 100 includes a first elastic member 150. One end of the first elastic member 150 is connected to the limiting member 120, and the other end of the first elastic member 150 is connected to the mounting platform 110. When the water tank 200 needs to be disassembled, the limiting member 120 is controlled to retract and not be higher than the mounting platform 110 at all. At this time, the first elastic member 150 is in a compressed state, and the limiting portion 212 of the box body 210 is no longer hindered by the limiting member 120 and is force-braked. The water tank 200 can slide in and out freely. After canceling the control of the limiting member 120, the first elastic member 150 returns to its original state and automatically drives the limiting member 120 to reset. Then, when the water tank 200 needs to be installed, the limiting member 120 is controlled to retract again. The first elastic member 150 is in a compressed state, and the water tank 200 is pushed so that the mating portion 211 is docked with the guiding portion 111. Then, the control of the limiting member 120 is canceled, and the first elastic member 150 returns to its original state, and part of the limiting member 120 protrudes out of the mounting platform 110 again and abuts against the limiting portion 212 to prevent the water tank 200 from slipping. By limiting the position of the limiting member 120 with the first elastic member 150, the water tank 200 can be installed more stably. In this embodiment, this solution is combined with the control member 140. Through the control member 140 that is connected to the limiting member 120 and part of which is always exposed outside the mounting platform 110, the movement of the limiting member 120 is controlled, and force is applied to the first elastic member 150, so that the compression state of the first elastic member 150 can be effectively and controllably controlled, which is more convenient for the patient to operate. This solution can also be combined with the first guide slope 121. The limiting portion 212 abuts against the first guide slope 121 to push the limiting member 120 to retract inward. At the same time, the first elastic member 150 is compressed. When the limiting portion 212 passes through the position where the limiting member 120 is located, the limiting portion 212 and the first guide slope 121 are no longer stressed, and the first elastic member 150 restores its deformation, and the limiting member 120 resets.

[0040] Specifically, as Figure 4 and Figure 6 shown, the guiding portion 111 is provided with a first flanging, and the mating portion 211 is provided with a second flanging. The first flanging and the second flanging are symmetrically and relatively clamped. Specifically, the guiding portion 111 is set as a forward L-shaped groove with a first flanging, and the mating portion 211 is set as a reverse L-shaped groove with a second flanging, and they are buckled with each other to ensure the firm connection between the water tank 200 and the body 100.

[0041] Optionally, the energy supply module 130 includes a heat conductor 131 and an energy supply assembly. The heat conductor 131 is protruded from the mounting platform 110. The heat conductor 131 is selectively communicatively connected with the energy supply assembly. When the water tank 200 is installed in place, the heat conductor 131 is coaxially fitted with the heating module 220. The heat conductor 131 is communicatively connected with the energy supply assembly to make the heat conductor 131 start to heat up. The standard water in the box body 210 can be heated by the heating module 220. Specifically, the standard water in the box body 210 can be purified water or other clean pure water that meets the requirements for the use of the ventilator.

[0042] In this embodiment, the energy supply module 130 includes a second elastic member 132, one end of the second elastic member 132 is connected to the heat conductive member 131, and the other end of the second elastic member 132 is connected to the energy supply assembly. When the second elastic member 132 is in the original state, the heat conductive member 131 is slightly higher than the mounting platform 110; when the water tank 200 is installed in place, the heat conductive member 131 and the heating module 220 are arranged in abutment with each other, and the heat conductive member 131 is slightly lowered and moved downward. At this time, the second elastic member 132 is in a compressed state, and the heat conductive member 131 is communicatively connected with the energy supply assembly, which can not only ensure that the ventilator can heat up normally, but also ensure that the energy supply module 130 and the heating module 220 maintain stable contact; when the water tank 200 is removed, due to the deformation force of the second elastic member 132, the accumulated elastic potential energy causes the heat conductive member 131 to bounce up slightly again, disconnecting the working state of the energy supply module 130.

[0043] Furthermore, a first sliding guide portion is provided on the heat conductive member 131, and a second sliding guide portion is provided on the heating module 220. The first sliding guide portion and the second sliding guide portion can slide relative to each other so that the heat conductive member 131 abuts against the heating module 220. When the heating module 220 on the water tank 200 is about to be aligned with the energy supply module 130 of the body 100, the second sliding guide portion is first brought into contact with the first sliding guide portion, and the water tank 200 continues to push, the first sliding guide portion is subjected to force, the heat conductive member 131 is slightly lowered and moved downward, the second elastic member 132 is converted into a compressed state, and the heat conductive member 131 begins to form a communication connection with the energy supply component, and then, the second sliding guide portion is staggered with the first sliding guide portion until the water tank 200 is installed in place, and the heating module 220 is completely fitted with the heat conductive member 131.

[0044] Exemplarily, the energy supply assembly includes an energy supply shell 133 and an energy supply body. The other end of the second elastic member 132 is connected to the energy supply shell 133. The energy supply shell 133 is detachably connected to the energy supply body to facilitate replacement of the energy supply body. The energy supply shell 133 can effectively protect the energy supply body, and the energy supply body is used to provide thermal energy for the heat conductor 131. Specifically, the energy supply body can be a motor, a coil or other components that can provide a heat source for the heating module.

[0045] In this embodiment, the machine body 100 is provided with a breathing interface 160, and the box body 210 is provided with a guiding interface 213. When the water tank 200 is approaching the specified position and about to complete the installation, the direction angle of the water tank 200 approaches the direction angle of the specified position, and the guiding interface 213 and the breathing interface 160 start to be guided and aligned, further ensuring that the installation alignment of the water tank 200 and the machine body 100 is accurate; when the water tank 200 is installed, the guiding interface 213 is hermetically sleeved inside the breathing interface 160, and the standard water in the water tank 200 generates air pressure after heating. The ventilator precisely uses the air pressure difference to assist in breathing during treatment, and the gas is discharged or enters through the guiding interface 213 and the breathing interface 160.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
