TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a sleep respirator. BACKGROUND

[0002] The disadvantages of the current mainstream sleep respirator are as follows: 1. The air path is complex, the air inlet pipeline is long, there are many turns, and the pipeline process is long; the fan air outlet pipeline needs to be converted in direction for multiple times to reduce noise. 2. There are many components, and the installation is complex. 3. The size is large, the weight is large, it is not easy to carry, and the weight is about 860g. It is not very convenient to carry, and it is not suitable for use during travel.

[0003] Therefore, the applicant discloses a respirator structure in Chinese patent application 2024101347215, which has a small size, a small weight, and is convenient to carry.

[0004] As shown in the above patent application, Figure 1a and 1b the respirator structure includes a main machine upper shell 1, a main machine lower shell 2, a main circuit board, a fan noise reduction cover (i.e. a pump cavity upper cover) 20, a fan wrapping sleeve 5, a fan 6, a main machine air inlet, and a main machine air outlet; the main machine upper shell and the main machine lower shell are buckled together; the fan wrapping sleeve is fixed between the main machine upper shell and the main machine lower shell, the fan is wrapped in the inner cavity of the fan wrapping sleeve, the fan noise reduction cover is arranged on the fan wrapping sleeve, and the main circuit board is arranged on the fan noise reduction cover; the main machine air inlet 7 is arranged on the main machine lower shell, the main machine air inlet is communicated with a spiral flow channel, the spiral flow channel is communicated with a fan upper air chamber 12 through a wrapping sleeve air hole on the fan wrapping sleeve, the fan upper air chamber is communicated with a fan air inlet 25, and a fan air outlet is connected with the main machine air outlet 8 through a wave-shaped shock absorption and noise reduction mechanism. The wrapping sleeve air hole is communicated with the spiral flow channel and the fan upper air chamber, the fan upper air chamber is surrounded by the fan noise reduction cover, the upper part of the fan shell, and the fan wrapping sleeve, and the wrapping sleeve opening is used to expose the fan air inlet. The spiral flow channel is jointly surrounded by the fan noise reduction cover, an air inlet pipe 3, a spiral rib plate 24 of the main machine lower shell, a fan lower air chamber 13, and the fan wrapping sleeve 5.

[0005] In summary, the above product has a small structure size and is convenient to carry, but because of the limitation of the structure space, the air inlet pipeline flow size is small under the premise of controlling noise, the overall air inlet amount is insufficient, and the maximum gas flow of the product as a whole is small. CONTENT OF THE UTILITY MODEL

[0006] The present application aims to provide a new sleep respirator air inlet pipeline scheme, and increase the maximum gas flow under the premise of not increasing noise.

[0007] To achieve the above-mentioned purposes of the application, the application provides a sleep breathing machine, which has a main machine upper shell and a main machine lower shell; the main machine upper shell and the main machine lower shell are buckled together; inside, a fan wrapping sleeve is fixed between a pump cavity upper cover and the main machine lower shell, forming a fan upper air cavity and a fan lower air cavity; air first enters the fan lower air cavity, then enters the fan upper air cavity through wrapping sleeve air holes on the fan wrapping sleeve, and then enters an air inlet of the fan through wrapping sleeve openings, is accelerated and pressurized in the fan, and is discharged from a main machine air outlet, forming an entire air path.

[0008] The main machine lower shell is provided with an air inlet cavity, which is connected to the fan lower air cavity through two pipelines of a first air inlet pipe and a second air inlet pipe, wherein one-way air enters the fan upper air cavity through a spiral flow channel between the first air inlet pipe and the wrapping sleeve air holes on the fan wrapping sleeve; another-way air enters the fan lower air cavity through the second air inlet pipe, and then enters the air inlet of the fan through the wrapping sleeve openings.

[0009] The first air inlet pipe is equivalent to the fan air inlet pipe in the background art. The second air inlet pipe is equivalent to an additional air inlet pipe based on the original one. This design is equivalent to increasing the flux cross-sectional area of the air inlet pipe as a whole, which is conducive to increasing the air flow. Moreover, this design does not increase the diameter of one of the pipelines. Thus, the general rule that the larger the diameter, the greater the noise is avoided.

[0010] As an improvement of the above technical solution, the spiral flow channel is jointly surrounded by the first air inlet pipe, a spiral rib plate of the main machine lower shell, the fan lower air cavity and the fan wrapping sleeve, wherein the air inlet of the first air inlet pipe is sealingly fixed to a side port of the air inlet cavity, and the first air inlet pipe is arranged in a circular arc shape along the inner wall of the fan lower air cavity. The air inlet of the second air inlet pipe is sealingly fixed to an inner port of the air inlet cavity. Further, the port part of the air inlet of the first air inlet pipe and / or the air inlet of the second air inlet pipe is provided with a flange, and the air inlet cavity is provided with a clamping groove corresponding to the port, for mounting the first air inlet pipe and the second air inlet pipe.

[0011] As another improvement of the above technical solution, the wrapping sleeve air holes on the fan wrapping sleeve include a pump cavity first through hole, a pump cavity second through hole and a pump cavity third through hole. The pump cavity second through hole is equivalent to the pump cavity through hole in the previous design. The pump cavity first through hole and the pump cavity third through hole are equivalent to some flux areas newly added on the basis of the original ones. This is conducive to increasing the air flow.

[0012] In actual application, the main machine lower shell is provided with a pump cavity rib plate, a first air inlet pipe inlet clamping groove, a first air inlet pipe outlet clamping groove, a second air inlet pipe clamping groove, an air inlet cavity upper cover sealing rib plate and a second air inlet pipe sealing rib plate.

[0013] As a further improvement of the above technical solution, the fan wrapping sleeve adopts a pump wrapping silica gel sleeve. The upper cover of the air inlet cavity is also designed on the pump wrapping silica gel, and is integrally formed by using silica gel material; and is embedded and sealed with the air inlet cavity upper cover sealing rib plate.

[0014] In addition, the main machine lower shell can also be provided with a sound-absorbing cotton fixing column located at the outlet of the two air inlet pipes, for clamping the sound-absorbing cotton between the fixing column and the rib plate. In this way, the noise of the fan part in the fan is filtered through the sound-absorbing cotton when it is transmitted outward through the air inlet pipe, and necessary noise reduction is performed.

[0015] The bottom of the pump wrapping silica gel sleeve can be sealed, that is, the fan wrapping sleeve also wraps the bottom of the fan. In this way, the noise of the motor part in the fan can be further minimized to be transmitted outward. In the original product scheme, the motor end of the fan bottom is not wrapped by silica gel. However, now that the second air inlet pipe is too close to the motor end, such wrapping is necessary.

[0016] The present application further designs a double-pipe air inlet structure on the original product, which effectively solves the problem of noise while increasing the flow of the fan. BRIEF DESCRIPTION OF DRAWINGS

[0035] The technical solutions of the present application will be described in detail below in combination with the drawings and examples. In these drawings, the same or similar components are denoted by the same or similar reference numerals. The fan and pump mentioned herein refer to the same component.

[0036] As shown in Figure 2a -d and Figure 6 , air enters the host air inlet cavity 10 from the air inlet cover 7, and two pipelines, the second air inlet pipe 4 and the first air inlet pipe 3, are installed in the air inlet cavity 10 to enter the lower part of the pump cavity. The first air inlet pipe 3 corresponds to the fan air inlet pipe in the background art. The second air inlet pipe 4 corresponds to an additional air inlet pipe added on the basis of the original. This design is equivalent to increasing the flux cross-sectional area of the air inlet pipe as a whole, which is beneficial to increasing the air flow. Moreover, such design does not increase the diameter of one of the pipelines. In this way, the general rule that "the larger the diameter, the louder the noise" is avoided. Among them Figure 2c and 2d respectively show the structure of the port part of the air inlet of the second air inlet pipe and the air inlet of the first air inlet pipe, which are provided with flanges 16 corresponding to the clamping grooves of the port of the air inlet cavity, so that the first air inlet pipe 3 and the second air inlet pipe 4 can be conveniently installed.

[0037] As shown in Figure 3 , the overall profile of the internal structure of the sleep ventilator of the present application includes the host air inlet 7, the first air inlet pipe 3, and the wrapping sleeve opening 11.

[0038] AsFigure 4a and 4b Figure 5 shows the structure of the pump silicone sleeve of the sleep ventilator of the present application; in this embodiment, the pump cavity first via hole 14, the pump cavity second via hole 9 and the pump cavity third via hole 15 are arranged on the pump silicone sleeve 5 (i.e. the fan wrapping sleeve 5). The pump cavity second via hole 9 here is equivalent to the pump cavity via hole in the previous design. The pump cavity first via hole 14 and the pump cavity third via hole 15 are equivalent to some new flux areas added on the basis of the original. In this way, the air inlet passes through the three via holes 14, 9, 15 into the upper fan cavity of the fan, which is conducive to increasing the air flow. As shown in Figure 1a Figure 6, the upper fan cavity 12 of the fan is the space formed between the pump cavity upper cover 20 and the fan wrapping sleeve 5.

[0039] The structure of the bottom shell 2 is shown in Figure 5a -e. The bottom shell is provided with a pump cavity rib plate 17, a first air inlet pipe inlet clamping groove 18, a first air inlet pipe outlet clamping groove 19 and a second air inlet pipe clamping groove 21. The second air inlet pipe clamping groove 21 is used to install the second air inlet pipe. The first air inlet pipe inlet clamping groove 18 is used to install the air inlet of the first air inlet pipe. The first air inlet pipe outlet clamping groove 19 is used to install the air outlet of the first air inlet pipe. The pump cavity rib plate 17 is used to support the pump silicone sleeve and form the lower part of the pump cavity (see Figure 1a and 1b Figure 7, the lower fan cavity 13 of the fan).

[0040] As shown in Figure 5a Figure 8, the first air inlet pipe 3 and the air inlet cavity upper cover 28 can also be designed on the pump silicone sleeve 5 and made of silicone material. The air inlet cavity upper cover 28 covers the air inlet cavity on the bottom shell and is connected and sealed with the air inlet cavity upper cover sealing rib plate 29. The air inlet cavity upper cover 28 is provided with a second air inlet pipe sealing rib plate 22 for sealing the joint of the second air inlet pipe at this point.

[0041] The external air enters the lower part of the pump cavity through the first air inlet pipe 3 and the second air inlet pipe 4. After passing through the lower part of the pump cavity, the air enters the fan inlet through the pump cavity first via hole, the pump cavity second via hole or the pump cavity third via hole.

[0042] The noise at the air inlet of the ventilator generally has two sources, one is generated by the air flow, and the other is generated by the rotation of the fan and transmitted to the air inlet. Because the pump cavity is sealed and installed around, the noise generated by the rotation of the fan is mainly conducted out through the air inlet pipe.

[0043] The bottom of the pump silicone sleeve 5 is sealed, which can minimize the transmission of the noise of the motor part of the fan to the outside. The bottom shell is provided with a sound-absorbing cotton fixing column 23 for clamping the sound-absorbing cotton between the fixing column 23 and the rib plate. The sound-absorbing cotton is placed at the outlets of the two air inlet pipes, so that when the noise of the fan part is transmitted to the outside through the air inlet pipe, it will pass through the sound-absorbing cotton and be necessary. The noise is reduced.

[0044] Finally, it should be noted that the above examples are merely intended to illustrate the technical solutions of the present application and not to limit. Although the present application is described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
