[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an anti-wear dry ash removal mixing chamber. The anti-wear dry ash removal mixing chamber includes an air guiding assembly 100, a connecting assembly 200, a switching assembly 300, and a housing assembly 400. It can prevent stable eddies from appearing in the mixing chamber, thus avoiding point-to-point wear of the mixing chamber.

[0033] Specifically, the air guiding assembly 100 includes a main pipe 101, a thick pipe 102, and a thin pipe 103. The thick pipe 102 is located at the bottom of the main pipe 101 and is sleeved on the outside of the thin pipe 103.

[0034] The gas guiding assembly 100 is located at the top of the mixing chamber. The top of the thick pipe 102 passes through the bottom of the middle part of the main pipe 101. The gas guiding assembly 100 is used to conduct the gas that is blown into the mixing chamber.

[0035] Specifically, the connecting component 200 connects the thick tube 102 and the thin tube 103, and includes a fixing ring 201, a rotating component 202 and a lifting component 203. The fixing ring 201 is located at the bottom of the thick tube 102, the rotating component 202 is located at the top of the thin tube 103, and the lifting component 203 is located inside the thick tube 102 and the thin tube 103.

[0036] The connecting component 200 allows the thin tube 103 to rotate about the axis of the thick tube 102, and at the same time move along the axial direction.

[0037] Specifically, the switch assembly 300 is located at the bottom of the air guide assembly 100 and includes a louver 301, a sliding column 302, and a limiting base 303. The louver 301 is located on the inner wall of the bottom of the air guide assembly 100, the sliding column 302 is located at the bottom of the louver 301, and the limiting base 303 is located at the bottom of the sliding column 302.

[0038] The switch assembly 300 controls whether gas flows through the louver 301. At the same time, the opening and closing of the louver 301 is subject to the gas pressure inside the air guide assembly 100. It will only open when the pressure is high enough.

[0039] Specifically, the outer casing assembly 400 is disposed outside the air guiding assembly 100 and includes an air inlet pipe 401, a main chamber 402 and an air outlet pipe 403. The main chamber 402 is disposed outside the air guiding assembly 100, the air inlet pipe 401 passes through and connects to one side of the main chamber 402, and the air outlet pipe 403 passes through and connects to the other side of the main chamber 402.

[0040] The outer casing assembly 400 is the original main body of the mixing chamber. To avoid point wear, the aforementioned air guide assembly 100, connection assembly 200 and switch assembly 300 are introduced.

[0041] Specifically, the main pipe 101 extends laterally through the intake pipe 401, the main chamber 402, and the exhaust pipe 403. The top of the thick pipe 102 and the bottom of the main pipe 101 are connected through it. The inner wall of the thick pipe 102 is provided with a first limiting ring groove K1.

[0042] The first limiting annular groove K1 on the inner wall of the thick tube 102 cooperates with the connecting component 200 to allow the thin tube 103 to rotate around the axis of the thick tube 102.

[0043] Specifically, the air guiding assembly 100 also includes a bend 104 and an inclined tube 105. The bottom of the thin tube 103 is fixedly connected to the bend 104, and the inclined tube 105 is located at the bottom of the bend 104.

[0044] Both the bend 104 and the inclined tube 105 are used to guide air.

[0045] In use, the air guiding assembly 100 is located at the top of the mixing chamber. The top of the thick pipe 102 extends through the bottom of the middle section of the main pipe 101. The air guiding assembly 100 is used to conduct the gas that is blown and disturbed in the mixing chamber. The connecting assembly 200 allows the thin pipe 103 to rotate around the axis of the thick pipe 102 and move along the axis. The switching assembly 300 controls the flow of gas through the opening and closing of the louver 301. The opening and closing of the louver 301 is limited by the gas pressure inside the air guiding assembly 100; it will only open when the pressure is high enough. The outer casing assembly 400 is the original main body of the mixing chamber. The air guiding assembly 100, connecting assembly 200, and switching assembly 300 are introduced to avoid point wear. The first limiting annular groove K1 on the inner wall of the thick pipe 102 cooperates with the connecting assembly 200 to allow the thin pipe 103 to rotate around the axis of the thick pipe 102. The bent pipe 104 and the inclined pipe 105 are also used for air guiding.

[0046] Before use, the louvers 301 are closed and the air guide assembly 100 is sealed. When the blower is turned on, the air pressure will act on the louvers 301 first and will not blow out and disturb the air in the mixing room.

[0047] Example 2

[0048] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0049] Specifically, the inner wall of the fixing ring 201 is fixedly connected to the outer wall of the bottom of the thick tube 102. The bottom of the fixing ring 201 is provided with a second limiting ring groove K2, and the bottom of the second limiting ring groove K2 is provided with a ring of limiting holes H1.

[0050] The second limiting ring groove K2 of the fixed ring 201 is used to prevent the rotating part 202 from disengaging from the fixed ring 201. The limiting hole H1 of the fixed ring 201 is used to adjust the initial position of the thin tube 103, the bent tube 104 and the inclined tube 105 each time the blower is turned on.

[0051] Specifically, the rotating component 202 includes a long column 202a, a coil spring 202b, and a short column 202c. One end of the long column 202a is fixedly connected to the outer end of the coil spring 202b, and the other end is engaged with the limiting hole H1. One side of the short column 202c is fixedly connected to the outer end of the coil spring 202b, and the other side is fixedly connected to the top of the thin tube 103.

[0052] Once the blower reaches a certain air pressure after being turned on, it will open the louvers 301, allowing airflow to pass through the thin tube 103, the bent tube 104, and the inclined tube 105, and blow it into the mixing chamber. The rotating component 202 ensures that when the inclined tube 105 is subjected to an unbalanced force, the thin tube 103 can rotate relative to the rotating component 202 until the coil spring 202b balances the unbalanced force, thus preventing the thin tube 103, the bent tube 104, and the inclined tube 105 from rotating continuously.

[0053] Specifically, the lifting component 203 includes a bottom ring 203a, a middle spring 203b, and a top ring 203c. The bottom ring 203a is fixed to the inner wall of the top of the thin tube 103, the middle spring 203b connects the bottom ring 203a and the top ring 203c, and the top ring 203c is fitted to the inner wall of the bottom of the thick tube 102.

[0054] The middle spring 203b ensures that the thin tube 103 can be translated along the axis of the thick tube 102.

[0055] In this way, the thin tube 103 and the thick tube 102 can rotate relative to each other and also translate relative to each other.

[0056] Specifically, the lifting component 203 also includes a top column 203d, a small spring 203e, and a limiting groove K4. The limiting groove K4 is evenly arranged around the outer wall of the top ring 203c. One end of the small spring 203e is fixed to the bottom of the limiting groove K4. The top column 203d is arranged in the limiting groove K4 and is fixedly connected to the other end of the small spring 203e. The top column 203d cooperates with the first limiting ring groove K1.

[0057] The bottom ring 203a of the lifting component 203 is fixed to the inner wall of the top of the thin tube 103, and the top ring 203c is engaged with the first limiting ring groove K1 of the bottom inner wall of the thick tube 102, so that the thin tube 103 and the thick tube 102 can rotate relative to each other.

[0058] Specifically, the louver 301 includes a fan blade 301a, a steering column 301b, and a rotating column 301c. The rotating column 301c is rotatably connected to the inner wall of the inclined tube 105. The steering column 301b passes through and connects to the fan blade 301a. The fan blade 301a is fitted to the inner wall of the inclined tube 105.

[0059] The steering column 301b has a protrusion on its side, and the fan blade 301a has a groove on its side where it is penetrated, and the two match. At the same time, the fan blade 301a has a protrusion on its side, and the inclined tube 105 has a groove on its inner wall, and the two also match. In this way, when the steering column 301b is raised or lowered, the connection between the side of the fan blade 301a and the inclined tube 105 will only rotate and not rise or fall. This allows the angle of the fan blade 301a to be adjusted, changing the on and off state of the air guide assembly 100.

[0060] Specifically, the inclined tube 105 has a vent H2 on its side, which is parallel to the fan blade 301a. The bottom of the inclined tube 105 has a switch hole H3, and the translation column 302 passes through the switch hole H3. The bottom of the steering column 301b and the top of the translation column 302 are fixedly connected.

[0061] The vent H2 is located on the side of the inclined tube 105. When the air guide assembly 100 is open, it will give the inclined tube 105 a lateral force, and the inclined tube 105 will rotate. At this time, the short column 202c of the rotating component 202 will rotate with the thin tube 103, causing the coil spring 202b to accumulate elastic potential energy until the coil spring 202b and the inclined tube 105 are in balance.

[0062] Specifically, the limiting base 303 includes a bottom fixing post 303a and a top limiting ring 303b. The top limiting ring 303b is located on the top of the bottom fixing post 303a. The bottom of the bottom fixing post 303a is fixedly connected to the main chamber 402. The top of the top limiting ring 303b is provided with a third limiting ring groove K3. The bottom of the translation post 302 cooperates with the third limiting ring groove K3.

[0063] When the blower is first turned on, the airflow passes through the air guide assembly 100 from the main pipe 101 to the thick pipe 102, thin pipe 103, bend pipe 104 and inclined pipe 105, and is finally intercepted by the louver 301. Due to the lack of air circulation, the thin pipe 103, bend pipe 104 and inclined pipe 105 move downward relative to the thick pipe 102, the middle spring 203b extends, and the translation column 302 cannot move downward because it is blocked by the top of the top limit ring 303b. Therefore, the steering column 301b at the top of the translation column 302 also cannot move downward. As a result, the steering column 301b rises relative to the fan blade 301a, the fan blade 301a is opened, the airflow flows out from the vent H2 on the side of the inclined pipe 105, the air guide assembly 100 is open, and the airflow blows into the mixing chamber.

[0064] Because the length required to adjust the fan blade 301a is very short, there will be a certain gap between the bottom of the translation column 302 and the bottom of the third limiting ring groove K3 at the beginning.

[0065] When the blower is first turned on, it will press the thin tube 103, the bent tube 104 and the inclined tube 105 downwards. As the wind force increases, the long column 202a of the rotating component 202 will slowly disengage from the limiting hole H1. When the thin tube 103 descends to a certain height, the long column 202a of the rotating component 202 has completely disengaged from the limiting hole H1. When the thin tube 103 descends to the point where the fan blades 301a change to allow airflow through the air guide assembly 100, the internal pressure of the air guide assembly 100 decreases sharply, the middle spring 203b releases elastic potential energy, and at the same time, the side vent H2 blows out air, causing the thin tube 103, the bent tube 104 and the inclined tube 105 to start rotating. Then the long column 202a of the rotating component 202 will insert back into the limiting hole H1, and it is highly likely that it will insert back into a different limiting hole H1.

[0066] During use, the thin tube 103, the bent tube 104, and the inclined tube 105 will move upwards slightly. This may cause the fan blade 301a to close again, or it may not. If it is not closed to maintain ventilation, the air guide assembly 100 will continue to output airflow to avoid fixed-point wear of the mixing chamber. If it is closed, the situation when the blower is first turned on will start again. The air guide assembly 100 will open again, and the long column 202a will replace the limit hole H1 again to adjust the blowing direction, which can better avoid fixed-point wear of the mixing chamber.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
