[0023] See also Figure 1-5A detachable air volume regulating valve comprises a detachable regulating valve body 100, a detachable external protection component 200 is arranged at the top of the detachable regulating valve body 100, the detachable external protection component 200 comprises a first connecting plate 210, a first connecting plate 210 is arranged at the top of the detachable regulating valve body 100, a second connecting plate 211 is inserted in the middle of the first connecting plate 210, and first grooves 212 are provided at both left and right ends of the second connecting plate 211.

[0024] A first plug plate 213 is inserted into the first groove 212, a second groove 214 is formed at the bottom of the first plug plate 213, a first moisture-absorbing pad 215 is glued into the second groove 214, third grooves 216 are formed at both left and right ends of the second connecting plate 211, first plug rods 217 are inserted into the third grooves 216, and a fixed connection assembly 300 is provided at the bottom of the first connecting plate 210.

[0025] Furthermore, the fixed connection assembly 300 includes a third connecting plate 310, and the third connecting plate 310 is fixed to the top of the detachable regulating valve body 100, and the left and right ends of the third connecting plate 310 are both provided with fourth grooves 311, and the left and right ends of the third connecting plate 310 are both provided with fifth grooves 312, and the bottom ends of the left and right sides of the first connecting plate 210 are both fixed with first connecting blocks 313.

[0026] The first connecting block 313 is inserted into the fourth groove 311, the bottom end of the first connecting block 313 is provided with a sixth groove 314, and the inside of the sixth groove 314 is provided with a second plug rod 315, which makes it more convenient for users to disassemble the first connecting plate 210, facilitates the use of users, and brings great convenience to users.

[0027] Furthermore, sliders are fixed on both sides of the second connecting plate 211, and sliding grooves are opened on both ends of the first connecting plate 210, so that the connection between the second connecting plate 211 and the first connecting plate 210 is more stable and the second connecting plate 211 is prevented from being pulled out from the first connecting plate 210.

[0028] Furthermore, a first rubber pad is glued to the surface of the right end of the first plugboard 213, and the first rubber pad fits the surface of the first plugboard 213, thereby increasing the friction between the user's hand and the surface of the first plugboard 213, making it more convenient for the user to exert force.

[0029] Furthermore, a spring is sleeved on the outer side of the second plug rod 315, and the spring is fixedly connected to the third connecting plate 310, so that the second plug rod 315 can be reset after being pulled by the user.

[0030] Furthermore, a second rubber pad is glued to the surface of the second insertion rod 315 away from the fifth groove 312, and the second rubber pad fits the surface of the second insertion rod 315, thereby increasing the friction between the user's hand and the surface of the second insertion rod 315, making it more convenient for the user to exert force.

[0031] In the specific implementation, first, when the user needs to rotate the top end of the detachable regulating valve body 100, the user pulls out the first plug plate 213 to pull the first plug plate 213 out from the first groove 212, and then, the user pulls out the first plug rod 217 to pull the first plug rod 217 out from the third groove 216.

[0032] The user presses the second connecting plate 211 to shrink the second connecting plate 211 into the first connecting plate 210 , so that the protective cover at the top of the detachable regulating valve body 100 can be lowered to facilitate the user to rotate the top of the detachable regulating valve body 100 .

[0033] By providing a first connecting plate 210 and a second connecting plate 211 at the top of the detachable regulating valve body 100, moisture in the air will not enter the interior of the detachable regulating valve body 100. Through the moisture absorption characteristics of the first moisture absorption pad 215 material, the moisture entering the first connecting plate 210 and the second connecting plate 211 is adsorbed to a certain extent, so that the top of the detachable regulating valve body 100 is always kept dry, and the top of the detachable regulating valve body 100 is protected from moisture to a certain extent.

[0034] Finally, when the user needs to dismantle the device, the user pulls the second plug rod 315 to disengage the second plug rod 315 and the sixth groove 314, and the user can easily pull the first connecting block 313 out from the fourth groove 311, making it more convenient for the user to disassemble the first connecting plate 210 and the second connecting plate 211.

[0035] When the user installs the first connecting plate 210 and the second connecting plate 211, the user again inserts the first connecting block 313 into the fourth groove 311 and inserts the second insert rod 315 into the sixth groove 314 to fix the first connecting block 313 to a certain extent, making the disassembly of the device more convenient.
