Description

[0002] The water treatment industry usually uses ultraviolet rays to disinfect water bodies. Ultraviolet disinfection refers to the principle that ultraviolet rays of appropriate wavelengths can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growing cells to die or / and regenerative cells to die, and ultimately achieving the effect of sterilization and disinfection.

[0093] In one embodiment, please refer to Figure 2 and Figure 4 , the first shaft sleeve 231 can move along the axial direction of the first cylindrical cavity relative to the sterilization cylinder 110, one end of the lamp cylinder 121 is in telescopic cooperation with the shaft end cover plate 232, and the other end of the lamp cylinder 121 is fixed to the other end of the sterilization cylinder 110.

[0094] After the first shaft sleeve 231 moves to the side of the lamp cylinder 121, the first shaft sleeve 231 can rotate relative to the sterilization cylinder 110; after the first shaft sleeve 231 moves to the side away from the lamp cylinder 121, the first shaft sleeve 231 cannot rotate relative to the sterilization cylinder 110.

[0095] As Figure 2In the view shown, the first shaft sleeve 231 can move left and right relative to the sterilization barrel 110 and the lamp barrel 121; when the first shaft sleeve 231 moves to the right, the first shaft sleeve 231 can rotate relative to the sterilization barrel 110, thereby entering the descaling working state; when the first shaft sleeve 231 moves to the left and returns to the original position, the first shaft sleeve 231 can no longer rotate relative to the sterilization barrel 110, thereby ending the descaling working state.

[0096] In one embodiment, referring to Figure 2 and Figure 4 , the first mounting assembly further comprises a third shaft sleeve 235 fixed to one end of the sterilization barrel 110, the first shaft sleeve 231 and the third shaft sleeve 235 are in telescopic cooperation, and the first shaft sleeve 231 can rotate relative to the third shaft sleeve 235, and the first liquid inlet cavity is in communication with the first shaft cavity through the third shaft sleeve 235.

[0097] As shown in the view shown in Figure 4 , the third shaft sleeve 235 is fixed to the first end cover 111 of the sterilization barrel 110, and the end of the third shaft sleeve 235 facing the first shaft sleeve 231 is provided with a boss to position the first shaft sleeve 231 and enable the first shaft sleeve 231 and the third shaft sleeve 235 to be in telescopic cooperation.

[0098] In one embodiment, referring to Figure 4 , the first shaft sleeve 231 is provided with a first limiting portion 2311, and the third shaft sleeve 235 is provided with a second limiting portion 2351.

[0099] After the first shaft sleeve 231 moves to the side of the lamp barrel 121, the first limiting portion 2311 is not in limiting cooperation with the second limiting portion 2351; after the first shaft sleeve 231 moves away from the side of the lamp barrel 121, the first limiting portion 2311 is in limiting cooperation with the second limiting portion 2351.

[0100] As shown in the view shown in Figure 4 and in combination with Figure 2 , when the first shaft sleeve 231 moves to the left, the first limiting portion 2311 is in limiting cooperation with the second limiting portion 2351, at this time the first shaft sleeve 231 cannot rotate relative to the third shaft sleeve 235, at this time it is not in the descaling working state; when the first shaft sleeve 231 moves to the right, the first limiting portion 2311 is separated from the second limiting portion 2351, at this time the first shaft sleeve 231 can rotate relative to the third shaft sleeve 235, thereby entering the descaling working state.

[0101] Optionally, one of the first limiting portion 2311 and the second limiting portion 2351 is a limiting groove, and the other of the first limiting portion 2311 and the second limiting portion 2351 is a limiting protrusion, the limiting protrusion and the limiting groove are in limiting cooperation.

[0102] For example, Figure 4 andFigure 5 As shown, the first limiting part 2311 is a limiting protrusion or limiting protrusion provided on the first bushing 231, and the second limiting part 2351 is a limiting groove provided on the third bushing 235. When the limiting protrusion is engaged in the limiting groove, the first bushing 231 cannot rotate relative to the third bushing 235. When the limiting protrusion is disengaged from the limiting groove, the first bushing 231 can rotate relative to the third bushing 235.

[0103] In one embodiment, please refer to Figure 2 The first mounting component also includes an elastic element 236, which is located inside the lamp tube 121. One end of the elastic element 236 abuts against the shaft end sealing plate 232, and the other end of the elastic element 236 abuts against one end of the ultraviolet lamp 122.

[0104] like Figure 2 From the perspective shown, the left end of the elastic element 236 abuts against the shaft end sealing plate 232, and the right end of the elastic element 236 abuts against the left end of the ultraviolet lamp 122. When the first bushing 231 moves to the right, the shaft end sealing plate 232 presses against the elastic element 236, and the first bushing 231 can rotate relative to the third bushing 235, thus entering the descaling working mode. After descaling is completed, the first bushing 231 returns to its original position under the restoring force of the elastic element 236, thereby limiting the engagement between the first bushing 231 and the third bushing 235, preventing them from rotating again, and ending the descaling working mode.

[0105] Optionally, the first bushing 231 can be moved toward the lamp tube 121 by increasing the amount of liquid entering the first shaft cavity, so that the first bushing 231 can rotate relative to the third bushing 235 and enter the descaling working mode; while the descaling working mode can be ended by reducing the amount of liquid entering the first shaft cavity and pushing the first bushing 231 to reset by the reset force of the elastic member 236.

[0106] Optionally, the elastic element 236 is a spring or an elastic convex ball.

[0107] In one embodiment, the first descaling device 210 has a first support portion and a first scraping portion. The first support portion extends in a spiral shape, and the first scraping portion is disposed on the first support portion and is used to scrape off dirt from the cavity wall of the first cylindrical cavity.

[0108] In one embodiment, the second descaling device 220 has a second support portion and a second scraping portion. The second support portion extends in a spiral shape, and the second scraping portion is disposed on the second support portion and is used to scrape off dirt on the outer wall of the lamp tube 121.

[0109] The first support part is a main body part of the first descaler 210 and is provided in a helical shape, and the first flow-through cavity is provided on the first support part and extends along the first support part. Similarly, the second support part is a main body part of the second descaler 220 and is provided in a helical shape, and the second flow-through cavity is provided on the second support part and extends along the second support part.

[0110] Optionally, the first scraping part and the second scraping part are provided with special scraping angles to achieve better scraping effect on dirt.

[0111] Optionally, the first support part and the second support part are made of wear-resistant and high-strength materials, and the first scraping part and the second scraping part are made of soft materials and have high-temperature-resistant and wear-resistant properties.

[0112] In one embodiment, as shown in Figure 2 , the sterilization cylinder 110 is further provided with a pollution discharge end 118, which is arranged at the bottom side of the sterilization cylinder 110 and located at the side of the sterilization cylinder 110 close to the first shaft sleeve 231; the first descaler 210 and the second descaler 220 both push the dirt to the side where the pollution discharge end 118 is located.

[0113] As shown in Figure 2 , the pollution discharge end 118 is arranged at the bottom side of the sterilization cylinder 110 and close to the left side, and the first descaler 210 and the second descaler 220 both push the dirt to the left side during the descaling process, so that the dirt is discharged through the pollution discharge end 118 at the bottom of the left side.

[0114] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 6 , the sterilization cylinder 110 is further provided with a second liquid inlet end 115, and the second liquid inlet end 115 and the first liquid inlet end 114 are both arranged at one end of the sterilization cylinder 110.

[0115] As shown in Figure 2 and Figure 6 , the second liquid inlet end 115 and the first liquid inlet end 114 are both arranged at the left end of the sterilization cylinder 110. During operation, if descaling is not needed, the second liquid inlet end 115 is opened, and the first liquid inlet end 114 can be opened or not opened, at this time, the liquid enters the sterilization cylinder 110 for sterilization treatment; when descaling is needed, the second liquid inlet end 115 is closed, and the first liquid inlet end 114 is opened, at this time, the water pressure in the first liquid inlet end 114 increases, thereby pushing the first shaft sleeve 231 away from the third shaft sleeve 235, thereby releasing the limitation of the first limiting part 2311 and the second limiting part 2351, so that the first shaft sleeve 231 can rotate relative to the third shaft sleeve 235, and then the liquid is sprayed out of the first liquid outlet hole 234, thereby pushing the first shaft sleeve 231 to rotate and enter the descaling working mode.

[0116] In one embodiment, referring to Figure 1 and Figure 2 , the sterilization barrel 110 is further provided with a second liquid outlet end 117, the first liquid outlet end 116 is arranged on the side of the sterilization barrel 110, and the second liquid outlet end 117 is arranged on the other end of the sterilization barrel 110.

[0117] In one embodiment, referring to Figure 1 and Figure 6 , the descaling mechanism further comprises a detector 250 arranged on the sterilization barrel 110, and the detector 250 is used to detect whether the sterilization mechanism needs to be descaled.

[0118] Optionally, the detector 250 is an ultraviolet intensity sensor.

[0119] The detector 250 can realize online real-time monitoring. When the ultraviolet intensity is poor, it indicates that the dirt has been more, and descaling needs to be performed. At this time, the descaling working mode can be started, and the descaling process does not need to stop.

[0120] The ultraviolet sterilization device has two working modes:

[0121] The first working mode is that when the detector 250 detects that the ultraviolet intensity is poor, the second liquid inlet end 115 is closed, the liquid enters from the first liquid inlet end 114, so as to drive the first shaft sleeve 231 to move away from the third shaft sleeve 235, and then the first shaft sleeve 231 can rotate relative to the third shaft sleeve 235. After the liquid is sprayed out through the first liquid outlet hole 234, the liquid generates a pushing force to drive the first shaft sleeve 231 to rotate, and then the descaling is started, and the dirt is discharged through the dirt discharge end 118. When the detector 250 detects that the ultraviolet intensity returns to the normal value, the second liquid inlet end 115 is opened, the water inlet pressure of the first liquid inlet end 114 is reduced, the first shaft sleeve 231 is reset under the pushing of the elastic member 236, the first shaft sleeve 231 no longer rotates relative to the third shaft sleeve 235, and is no longer in the descaling mode. This working mode is suitable for the case that the water quality of the liquid is good.

[0122] The second working mode is that the second liquid inlet end 115 is always closed, the first liquid inlet end 114 is always opened, the liquid enters from the first liquid inlet end 114, and the first shaft sleeve 231 can always rotate relative to the third shaft sleeve 235 and rotate under the pushing force of the liquid sprayed from the first liquid outlet hole 234, so that the first descaler 210 and the second descaler 220 always perform the descaling operation. This working mode is suitable for the case that the water quality of the liquid is complex, the impurity content is high, and the viscosity is large.
