Both the threaded hole and the fixing hole 4102 are threadedly connected to the fasteners so that the panel 410 is connected to the base plate 1112.

[0196] like Figure 1 , Figure 8 As shown, in some embodiments, the second fixing structure 820 includes a positioning platform 8201 and a locking block 8202; the positioning platform 8201 is disposed in the recess 120; the locking block 8202 is disposed on the positioning platform 8201, and the humidification part 220 of the ventilator is provided with a locking groove 2205 that cooperates with the locking block 8202.

[0197] The detachable connection between the humidification section 220 and the housing is achieved by setting a card slot 2205 block to cooperate with the card slot 2205, which is simple and convenient.

[0198] like Figure 8As shown, it should be noted that the humidification unit 220 includes a water tank 2204, which abuts against the positioning platform 8201, and the slot 2205 is provided on the water tank 2204.

[0199] like Figure 4 , Figure 5 As shown, in some embodiments, the housing includes a support plate 160 and a shock-absorbing plate; the support plate 160 is detachably connected to the bottom of the base plate 1112; the shock-absorbing plate is disposed between the base plate 1112 and the support plate 160; wherein, the support plate 160 is provided with a third fixing structure for detachably connecting to the battery assembly 60 of the ventilator.

[0200] By setting up a support plate 160 to provide a structural foundation for installing the battery assembly 60, and by detachably connecting the third fixing structure to the battery assembly 60, the assembly efficiency of the ventilator is further improved, while facilitating disassembly and maintenance; by setting up a shock-absorbing plate to buffer and absorb shock, noise is reduced.

[0201] It should be noted that, as Figure 3 As shown, a fixing strip 1115 is provided at the bottom of the base plate 1112, and a fixing groove is provided on the support plate 160 to cooperate with the fixing strip 1115. The fixing strip 1115 is inserted into the fixing groove to realize the detachable connection between the support plate 160 and the base plate 1112.

[0202] It should also be noted that damping plates include, but are not limited to, foam boards.

[0203] It should also be noted that the battery assembly 60 is used for power supply, ensuring that the ventilator can still operate normally in the event of a power outage, thereby improving the versatility and safety of the ventilator.

[0204] like Figure 4 , Figure 5 As shown, in some embodiments, the third fixing structure includes a positioning ring 8301, a second male buckle 8302, and an electrical male buckle; the positioning ring 8301 is disposed at the bottom of the support plate 160, and the positioning ring 8301 has a first side and a second side facing each other; the second male buckle 8302 is disposed on the first side of the positioning ring 8301, and the battery assembly 60 of the ventilator is provided with a second female buckle 610 that cooperates with the second male buckle 8302; the third male buckle 8303 is disposed on the second side of the positioning ring 8301, and the battery assembly 60 of the ventilator is provided with a third female buckle 620 that cooperates with the third male buckle 8303.

[0205] The positioning ring 8301 is used to position the battery assembly 60 during installation, thereby improving installation efficiency. The second male buckle 8302 and the third male buckle 8303 are respectively set on the opposite sides of the positioning ring 8301 to improve the reliability and stability of the connection and prevent the battery assembly 60 from falling off.

[0206] It should be noted that, as Figure 9 As shown, the battery assembly 60 includes a battery box and a battery disposed inside the battery box, and the second female buckle 610 and the third female buckle 620 are both disposed on the battery box.

[0207] It should also be noted that the structures of the second male buckle 8302, the second female buckle 610, the third male buckle 8303, and the third female buckle 620 are all existing technologies, and will not be described in detail in this application.

[0208] It should also be noted that the number of the second public card buckle 8302 and the third public card buckle 8303 can be set as needed, for example, such as Figure 4 , Figure 5 As shown, there are two second public card buckles 8302 and one third public card buckle 8303.

[0209] like Figure 11 As shown, in some embodiments, the main body 110 is provided with an air inlet 1109, a gas outlet 1106, a first gas inlet 1107, and a second gas inlet 1108.

[0210] It should be noted that, as Figure 11 As shown, air inlet 1109 and second gas inlet 1108 are both located on the second side wall 1103, and gas outlet 1106 and first gas inlet 1107 are both located on the fourth side wall 1105.

[0211] It should also be noted that the air inlet 1109 is equipped with a perforated cover plate, which serves to prevent dust while ensuring normal air intake.

[0212] Example 2

[0213] At least one embodiment of the present invention also provides a ventilator, including the housing of any embodiment of the present invention, thereby having all the technical effects brought about by the technical solutions of the above embodiments.

[0214] like Figure 10 As shown, in some embodiments, the ventilator includes a display assembly 40, a humidification unit 220, and a battery assembly 60 that are detachably connected to the housing.

[0215] Example 3

[0216] A ventilator draws air in with a fan and then delivers it to the user through a humidifier. The humidifier is a crucial component of the ventilator; it heats and humidifies the air, reducing the irritation of the respiratory mucosa caused by cold, dry air. To minimize air condensation, the hot air exiting the ventilator is typically connected to a heated tubing.

[0217] However, the applicant discovered at least the following problems in the prior art: hot air from the humidifier is prone to condensation when flowing through the tubing between the humidifier outlet and the ventilator outlet, producing condensate and affecting the normal use of the ventilator.

[0218] To solve the above-mentioned technical problems, at least one embodiment of the present invention provides a heating pipeline structure and a ventilator, including a shell assembly 10, a main body assembly 20, and a heating pipeline interface 30; the main body assembly 20 is disposed on the shell assembly 10, and the main body assembly 20 is used to introduce gas and humidify and heat the gas, and an air outlet 2207 is provided on the main body assembly 20; the heating pipeline interface 30 passes through the shell assembly 10, one end of the heating pipeline interface 30 is connected to the air outlet 2207, and the other end is used to connect to an external pipeline, and the heating pipeline interface 30 can keep the gas heated by the main body assembly 20 warm.

[0219] As can be seen from the above, by connecting the outlet 2207 to the external pipeline through the heating pipe interface 30, the heated gas leaving the main component 20 is kept warm in a timely manner. The heating pipe interface 30 serves as an insulation pipe, providing a warming path for the heated gas. Before flowing into the external pipeline, the heated gas is prevented from cooling and generating condensate, thus ensuring the normal use of the ventilator. This solves the problem that existing hot air easily generates condensate when flowing through the pipeline between the humidification section outlet 2207 and the ventilator outlet 2207, which affects the normal use of the ventilator.

[0220] like Figure 10 , 12 As shown, the ventilator includes a housing assembly 10, a main body assembly 20, and a heating tubing interface 30. The main body assembly 20 is disposed on the housing assembly 10 and is used to introduce gas and humidify and heat the gas. The main body assembly 20 is provided with an air outlet 2207. The heating tubing interface 30 passes through the housing assembly 10. One end of the heating tubing interface 30 is connected to the air outlet 2207, and the other end is used to connect to an external pipeline. The heating tubing interface 30 can keep the gas heated by the main body assembly 20 warm.

[0221] It should be noted that the end of the external pipeline away from the heating pipeline is connected to the breathing mask. The external pipeline can be a heating pipeline to keep the gas warm and prevent the gas from cooling and producing condensation.

[0222] It should also be noted that the gases include oxygen and / or air.

[0223] The heating pipe interface 30 connects the air outlet 2207 to the external pipeline, which keeps the heated gas leaving the main component 20 warm in time. This prevents the heated gas from cooling down and generating condensate before flowing into the external pipeline, thus solving the problem that existing hot air easily generates condensate when flowing through the pipeline between the humidification section air outlet 2207 and the ventilator air outlet 2207, which affects the normal use of the ventilator.

[0224] like Figures 13-15 , Figure 17 As shown, in some embodiments, the heating pipeline interface 30 includes a pipeline body 310, a heating element 320, and a heating link 330; the pipeline body 310 passes through the housing assembly 10; the heating element 320 is disposed on the pipeline body 310 and is used to heat and keep the pipeline body 310 warm; the heating link 330 is disposed inside the housing assembly 10 and is electrically connected to the heating element 320.

[0225] The heating element 320 is powered through the heating link 330, enabling the heating element 320 to work; the heating element 320 heats the pipeline body 310, enabling the pipeline body 310 to have the function of heat preservation of gas.

[0226] It should be noted that, as Figure 15 As shown, the heating element 320 can be a ring structure. The heating element 320 is sleeved on the outer wall of the first pipeline section 3101 and is detachably connected to the first pipeline section 3101. The heating element 320 is an electric heating element that converts electrical energy into heat energy.

[0227] like Figures 13-15 As shown, in some embodiments, the pipeline body 310 and the housing assembly 10 are connected, and a limiting ring 3103 is provided on the outer wall of the pipeline body 310, the limiting ring 3103 abutting against the inner wall of the housing assembly 10.

[0228] The limit ring 3103 is set to limit the installation of the pipe body 310, which facilitates the installation of the pipe body 310 and improves the installation efficiency.

[0229] It should be noted that the outer wall of the pipeline body 310 is provided with a plurality of fixing seats 3104 arranged circumferentially around the pipeline body 310. The fixing seats 3104 are connected to the limiting ring 3103. The fixing seats 3104 abut against the inner wall of the housing assembly 10. The fixing seats 3104 are connected to the housing assembly 10 by screws, thereby realizing the connection between the pipeline body 310 and the housing assembly.

[0232] It should also be noted that the first electrical connector 3301 and the second electrical connector 3302 are mechanical electrical connectors that enable detachable connections between circuit devices, components, or assemblies. They are used to transmit signals and current and control the on / off state of the connected circuit. For example, the first electrical connector 3301 is a terminal block, and the second electrical connector 3302 is provided with multiple metal pins for conducting electrical signals.

[0233] like Figure 12 , Figure 18 As shown, in some embodiments, the housing assembly 10 includes a main body 110 and a recess 120; the main body 110 has a cavity 1101; the recess 120 is disposed on one side of the main body 110; wherein, the main body 110 is provided with a gas outlet 1106, a first gas inlet 1107, and a second gas inlet 1108, and the first gas inlet 1107 and the second gas inlet 1108 are for the pipeline body 310 to pass through.

[0234] The main body 110 and recessed portion 120 provide a structural foundation for the installation of the main body component 20 and the heating pipe interface.

[0235] It should be noted that, as Figure 11 , Figure 12 , Figure 16 , Figure 18 , Figure 19 As shown, the main body 110 includes a first sidewall 1102 and a second sidewall 1103 opposite to each other. The opening of the cavity 1101 is provided on the first sidewall 1102. The second sidewall 1103 is provided with an air inlet 1109, a DC interface 150 and a groove 1117. The air inlet 1109 is provided with a perforated cover plate, which can prevent dust while ensuring normal air intake. The second gas inlet 1108 is provided in the groove 1117.

[0236] The main body 110 includes a third side wall 1104 and a fourth side wall 1105, which are located between the first side wall 1102 and the second side wall 1103. The gas outlet 1106 and the first gas inlet 1107 are both provided on the fourth side wall 1105, and the recess 120 is provided on the fourth side wall 1105.

[0237] It should also be noted that, such as Figure 15 As shown, the pipeline body 310 includes a first pipeline section 3101 and a second pipeline section 3102. The first pipeline section 3101 passes through the first gas inlet 1107, and the second pipeline section 3102 passes through the second gas inlet 1108. The first pipeline section 3101 and the second pipeline section 3102 are connected and perpendicular to each other, so as to cooperate with the perpendicular first gas inlet 1107 and the second gas inlet 1108. A limiting ring 3103 is disposed on the second pipeline section 3102 and is located in the groove 1117. The fixing seat 3104 is located outside the groove 1117 and abuts against the second side wall 1103.

[0238] It should also be noted that, such as Figure 18 , Figure 19 As shown, the main body 110 and the recessed portion 120 are integrally formed. It should also be noted that the housing assembly 10 includes a base 130 connected to the bottom of the recessed portion 120. The bottom surface of the housing assembly 10 is provided with a plurality of silicone pads 140, which are respectively disposed at the corners of the bottom surface of the housing assembly 10. The silicone pads 140 play a shock-absorbing role, effectively reducing vibration noise and ensuring the normal operation of the equipment.

[0239] In some embodiments, such as Figure 16 As shown, the main body 110 is provided with an annular boss 1111 surrounding the second gas inlet 1108, and the end face of the annular boss 1111 abuts against the limiting ring 3103.

[0240] By setting an annular boss 1111 around the second gas inlet 1108, support is provided for the pipeline body 310 when it passes through the second gas inlet 1108, increasing the contact area with the pipeline body 310, thereby improving the stability and reliability of the pipeline body 310 installation.

[0241] It should be noted that a portion of the annular boss 1111 is located inside the groove 1117, while the other portion of the annular boss 1111 is located outside the cavity 1101, thereby avoiding occupying the space of the cavity 1101.

[0242] In some embodiments, such as Figure 14 As shown, a first sealing element 340 is provided between the annular boss 1111 and the limiting ring 3103.

[0243] By setting the first sealing element 340, the sealing performance is improved, preventing gas leakage, which would reduce the amount of gas and affect the user experience.

[0244] It should be noted that a limiting groove is provided on the end face of the annular boss 1111 that abuts against the limiting ring 3103, and the first sealing element 340 is located in the limiting groove.

[0245] It should also be noted that the first sealing element 340 includes, but is not limited to, an O-ring.

[0246] like Figure 12 , Figures 18-20 As shown, in some embodiments, the main component 20 includes a fan section 210 and a humidification section 220; the fan section 210 is disposed in the cavity 1101, the fan section 210 has an air outlet 2101, and the fan section 210 is used to introduce gas; the humidification section 220 is disposed in the recess 120, the humidification section 220 has an air inlet 2206, and the humidification section 220 is used to humidify and heat the gas introduced by the fan section 210; wherein, the air outlet 2207 is disposed on the humidification section 220, the air outlet 2101 is connected to the gas outlet 1106, and the gas outlet 1106 is connected to the air inlet 2206.

[0247] By introducing air from the external environment through the fan unit 210, and humidifying and heating the introduced air through the humidification unit 220, the irritation of cold, dry air to the user's respiratory mucosa is reduced. The air outlet 2101 is connected to the gas outlet 1106, and the gas outlet 1106 is connected to the air inlet 2206, introducing air from the external environment into the humidification unit 220, providing the structural basis for humidification and heating.

[0248] It should be noted that the fan unit 210 includes a housing, a fan installed inside the housing, and a shock absorber 2102 installed at the bottom of the housing. The housing is provided with a duct for gas flow, which is connected to the fan. An air inlet and an air outlet 2101 are respectively installed at both ends of the duct, and the air inlet is connected to the air inlet 1109.

[0249] It should also be noted that, such as Figure 18 As shown, the humidification section 220 includes a support 2201, a heating element 2202, a heat-conducting element 2203, and a water tank 2204; the support 2201 is disposed on the recessed section 120; the heating element 2202 is disposed on the support 2201; the heat-conducting element 2203 is disposed on the heating element 2202; the water tank 2204 is disposed on the heat-conducting element 2203, and the water tank 2204 is detachably connected to the recessed section 120.

[0250] The water in the water tank 2204 is heated by the heating element 2202 and the heat-conducting element 2203, resulting in high heating efficiency and rapid evaporation of the water. The evaporated water vapor comes into contact with the gas introduced into the humidification section 220, thereby heating and humidifying the gas. The detachable connection between the water tank 2204 and the recessed section 120 facilitates the disassembly and replacement of the water tank 2204.

[0251] It should be noted that the heating element 2202 includes, but is not limited to, a silicone heating sheet; the heat-conducting element 2203 includes, but is not limited to, an aluminum heat-conducting element or a copper heat-conducting element; and the heating element 2202 is connected to the heat-conducting element 2203 by means of bonding.

[0253] By installing a second seal 230 at the connection between the gas outlet 1106 and the air inlet 2206, the sealing performance is improved, preventing gas leakage when it is introduced into the humidification section 220, which would reduce the gas volume and affect the user experience. By installing a second seal 230 at the connection between the air outlet 2207 and the heating pipeline interface 30, the sealing performance is improved, preventing gas leakage when it leaves the humidification section 220 after heating and humidification. Leaked gas is prone to condensation, which would affect the normal operation of the ventilator.

[0254] It should be noted that the second seal 230 includes, but is not limited to, a silicone seal.

[0255] It should also be noted that the second seal 230 at the connection between the gas outlet 1106 and the air inlet 2206, and at the connection between the air outlet 2207 and the heating pipeline interface 30, can be two separate seals or two seals connected by an integral molding process.

[0256] Example 4

[0257] At least one embodiment of the present invention also provides a ventilator, including a heating tubing structure according to any embodiment of the present invention, thereby having all the technical effects brought about by the technical solutions of the above embodiments.

[0260] like Figure 7 As shown, in some embodiments, the display component 40 includes a panel 410 and a display screen 420. The panel 410 is disposed on the opening of the cavity 1101 and has a plurality of buttons 430. The display screen 420 is disposed on the side of the panel 410 away from the main body 110.

[0261] It should be noted that the bottom of the panel 410 is connected to the main body 110 by screws, among other things, and the display screen 420 is connected to the panel 410 by adhesive, among other things.

[0262] like Figure 20 As shown, in some embodiments, the control component 50 includes a first substrate 510 and a second substrate 520; the first substrate 510 is disposed in the cavity 1101 and is electrically connected to the main component 20 and the heating pipe interface 30; the second substrate 520 is disposed on the panel 410 and is electrically connected to the display screen 420; wherein, the first substrate 510 and the second substrate 520 are electrically connected.

[0263] The second substrate 520 is electrically connected to the display screen 420 to receive commands input by the user on the display screen 420. The second substrate 520 is also electrically connected to the first substrate 510 to transmit electrical signals. This allows the first substrate 510 to control the main component 20 and the heating pipe interface 30 to operate according to the user commands transmitted by the second substrate 520, and to feed back electrical signals to the second substrate 520. The second substrate 520 then displays the real-time operating information of the main component 20 and the heating pipe on the display screen 420.

[0264] It should be noted that both the first substrate 510 and the second substrate 520 are circuit boards. The first substrate 510 is mounted on the main body 110 with screws, and the second substrate 520 is mounted on the panel 410 with screws. The first substrate 510 and the second substrate 520 are electrically connected by a ribbon cable.

[0266] It should also be noted that a first signal processing circuit is provided on the first substrate 510, and a second signal processing circuit is provided on the second substrate 520.

[0267] Example 5

[0268] The gas supplied by a ventilator usually needs to maintain an oxygen concentration within a comfortable range for the human body, especially for patients who need a ventilator to maintain their breathing, who are more sensitive to the oxygen concentration of the gas entering their body.

[0269] However, the applicant found that the prior art has at least the following problems: when the gas delivered to the patient by the ventilator is a mixture of oxygen and air, the oxygen concentration is prone to be too high or too low, causing discomfort to the patient.

[0270] like Figure 21 , Figure 24 As shown, the ventilator includes a housing assembly 10, a main body assembly 20, a sensor 70, and a control assembly 50. The housing assembly 10 includes an air inlet 1109 and an oxygen inlet 1110. The main body assembly 20 is disposed within the housing assembly 10 and includes an air duct that is connected to the air inlet 1109 and the oxygen inlet 1110, respectively. The main body assembly 20 is used to introduce gas and humidify and heat the gas. The sensor 70 is disposed on the air duct and senses the oxygen concentration of the gas and generates a corresponding sensing electrical signal. The control assembly 50 is disposed within the housing assembly 10 and receives the sensing electrical signal and monitors the oxygen concentration of the gas based on the sensing electrical signal.

[0271] By providing an air inlet 1109 and an oxygen inlet 1110 connected to the air duct on the housing assembly 10, separate inlets are provided for the ventilator to input air and oxygen, allowing users to select according to their needs, greatly improving flexibility and practicality. Simultaneously, both the air inlet 1109 and the oxygen inlet 1110 are connected to the air duct, allowing air and oxygen to mix within the duct. The sensor 70 senses the oxygen concentration of the gas and generates a corresponding sensing electrical signal. The control assembly 50 receives the sensing electrical signal generated by the sensor 70, enabling monitoring of the oxygen concentration of the gas and ensuring that the oxygen concentration is within a suitable range. This solves the problem of excessively high or low oxygen concentration when the existing ventilator delivers a mixture of oxygen and air.

[0272] It should be noted that the sensing element 70 includes, but is not limited to, an oxygen concentration sensor. The oxygen concentration sensor is an outsourced component, and its specific structure is existing technology, which will not be described in detail in this application.

[0273] It should also be noted that the sensing element 70 can generate a corresponding sensing electrical signal based on the oxygen concentration of the gas, and transmit the corresponding sensing electrical signal to the control component 50. After analysis and processing by the control component 50, the display component 40 displays the current oxygen concentration so that the user can know the current oxygen concentration in a timely manner.

[0276] like Figure 23 As shown, it should be noted that multiple silicone pads 140 are provided on the bottom surface of the support base 180. The multiple silicone pads 140 are respectively located at the corners of the bottom surface of the support base 180. The silicone pads 140 play a shockproof role, effectively reducing vibration noise and ensuring the normal operation of the equipment.

[0277] It should also be noted that the material of the shock absorber 1301 can be foam, and the shock absorber 1301 and the support 180 are connected by means of bonding, including but not limited to bonding.

[0326] Ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used in respiratory failure due to various causes, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation. A ventilator draws in air with a fan, then heats and humidifies it before delivering the warm air to the user. To reduce gas condensation, the warm air discharged from the ventilator outlet is usually connected to a heated tubing. However, the applicant has discovered at least the following problems with the existing technology: warm air is prone to condensation when flowing through the ventilator outlet, producing condensate that affects the normal use of the ventilator.

[0327] like Figure 11 , Figure 13 , Figure 14 , Figure 27 As shown, the heating structure includes a housing assembly 10 and a heating assembly; the heating assembly includes a pipe body 310 and a heating element 320 detachably disposed on the housing assembly 10. The pipe body 310 is used to connect to an external pipe, and the heating element 320 can heat and keep the gas inside the pipe body 310 warm.

[0328] The tubing body 310 is connected to an external pipeline, allowing hot air supplied by the ventilator to be discharged into the external pipeline. A heating element 320 heats and insulates the gas inside the tubing body 310, ensuring timely insulation of the hot air leaving the housing assembly 10. This prevents condensation from forming on the heated air before it flows into the external pipeline, thus guaranteeing the normal operation of the ventilator. This solves the problem of existing systems where hot air easily condenses when flowing through the ventilator outlet, affecting its normal operation. The detachable connection between the heating element 320, the tubing body 310, and the housing assembly 10 facilitates assembly and disassembly.

[0329] It should be noted that the end of the external pipeline away from the pipeline body 310 is connected to the breathing mask. The external pipeline can be a heating pipeline to keep the gas warm and prevent the gas from cooling and producing condensation.

[0360] A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used for respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, occupying a very important position in the field of modern medicine. Existing ventilator masks typically have an oxygen interface, requiring the oxygen tube to be inserted into the mask interface during use. For example, Chinese patent CN206334181U discloses a connection structure between a non-invasive ventilator mask and an oxygen tube, allowing for a relatively secure connection between the oxygen tube and the ventilator mask, preventing the oxygen tube from easily detaching from the mask. This oxygen supply method requires an additional oxygen tube connected to the mask, which can interfere with the user's activities such as getting out of bed, resulting in a poor user experience.

The input oxygen is mixed with air through the fan unit 210, enters the humidification unit 220, and is then supplied to the user for breathing. Therefore, there is no need to connect the oxygen tubing to the ventilator mask, resulting in a better user experience. The sensor 70 can monitor the oxygen concentration of the gas in the humidification unit 220, and can promptly detect abnormal oxygen concentrations to protect the user's health.

[0363] It should be noted that the sensing element 70 is an oxygen concentration sensor.

[0364] like Figure 39 As shown, one embodiment of the ventilator further includes a first connecting tube 5 and a second connecting tube 6. The two ends of the first connecting tube 5 are connected to an oxygen connector 11 and a blower unit 210, respectively. The two ends of the second connecting tube 6 are connected to a humidification unit 220 and a sensor 70, respectively. Oxygen introduced from the oxygen connector 11 first enters the blower unit 210 through the first connecting tube 5, mixes with air, and then is input into the humidification unit 220 from the blower unit 210. When the humidified gas is output, a portion enters the sensor 70 through the second connecting tube 6, thereby monitoring the oxygen concentration of the output gas. Both the first connecting tube 5 and the second connecting tube 6 can be flexible hoses for easy bending and installation inside the housing assembly 10, while also maintaining a lower cost.

[0365] like Figure 40 As shown, one embodiment of the ventilator also includes a heated tubing interface 30, which is disposed on the housing assembly 10 and communicates with the humidification unit 220. The heated tubing interface 30 is connected to the ventilator's heated tubing (not shown in the figure). The gas output from the humidification unit 220 reaches the ventilator's mask (not shown in the figure) through the heated tubing. During this process, the gas can be maintained at a temperature suitable for human inhalation, and no condensation will be generated in the heated tubing.

[0366] like Figure 41 As shown, specifically, the humidification unit 220 includes a water tank 2204 and an air inlet 2206 and an air outlet 2207 disposed on the water tank 2204. A heating pipe interface 30 is connected to the air outlet 2207, and a second connecting pipe 6 is connected to the heating pipe interface 30. The fan unit 210 is connected to the air inlet 2206 to communicate with the interior of the water tank 2204. The second connecting pipe 6 is connected to the heating pipe interface 30, allowing a portion of the gas output from the heating pipe interface 30 to enter the sensing element 70 through the second connecting pipe 6, thereby enabling monitoring of the gas oxygen concentration.

[0367] like Figure 40 and Figure 41 As shown, furthermore, there are two second connecting pipes 6, and the sensing element 70 includes two connectors 701, with each of the two second connecting pipes 6 connected to one connector 701. The sensing element 70 has an internal channel for gas flow (not shown in the figure), and both connectors 701 are connected to this channel. When the two second connecting pipes 6 are connected to one connector 701, the outlet 2207, the two second connecting pipes 6, and the interior of the sensing element 70 together form a gas flow loop. The gas output from the outlet 2207 can be delivered to the sensing element 70 more effectively and quickly, making the oxygen concentration value detected by the sensing element 70 more accurate.

[0368] like Figures 35 to 37 As shown, one embodiment of the ventilator also includes a protective cover 7, which is disposed on the surface of the housing assembly 10. The protective cover 7 can seal the end of the oxygen connector 11 located outside the housing assembly 10. When the oxygen tube is not needed, the protective cover 7 can seal the oxygen connector 11 to prevent external dust or other foreign objects from entering the oxygen connector 11 and keep the oxygen connector 11 clean.

[0369] like Figure 37 As shown, the surface of the housing assembly 10 is provided with a positioning groove 100, into which the protective cover 7 can be snapped. By providing the positioning groove 100, the protective cover 7 can be well fixed and is not easily dislodged due to movement or vibration of the ventilator.

[0370] Furthermore, the protective cover 7 includes a cover body 71, a flexible connecting part 72, and a fixing post 73. The flexible connecting part 72 is connected to the edge of the cover body 71, and the fixing post 73 is disposed on the flexible connecting part 72. The bottom of the positioning groove 100 has a fixing hole 200 for the fixing post 73 to be inserted. When the cover body 71 is removed from the positioning groove 100, the protective cover 7 will not fall off due to the fixing action of the fixing post 73, thus preventing the protective cover 7 from being lost. The flexible connecting part 72 allows the protective cover 7 to be flipped, thereby smoothly completing the fixing and removal operations of the cover body 71. The protective cover 7 can be made of materials such as rubber or silicone.

[0371] like Figure 36 As shown, one embodiment of the ventilator also includes a heating element 2202, which is disposed on the housing assembly 10, such as... Figure 42 As shown, a heat-conducting element 2203 is provided at the bottom of the humidification section 220, and a heating element 2202 is connected to the heat-conducting element 2203. The heating element 2202 can transfer heat to the heat-conducting element 2203, thereby raising the water temperature in the humidification section 220 to a suitable temperature range, so that the output gas is kept at a temperature suitable for the human body.

[0372] like Figure 34 As shown, one embodiment of the ventilator also includes a panel 9, which is connected to one side of the housing assembly 10 and forms a cavity for accommodating the fan section 210, as shown. Figure 43 As shown, the water tank 2204 is located outside the housing assembly 10, and is detachably connected to one side of the housing assembly 10, for example, by a snap-fit ​​connection. Placing the fan unit 210 inside the housing assembly 10 prevents it from being directly impacted by external forces. The location of the water tank 2204 outside the housing assembly 10 facilitates disassembly of the water tank 2204, making it convenient for adding water or cleaning operations.
