[0002] With the continuous development of society, people's demands for hygiene, environment, and health are becoming increasingly urgent. Food purifiers have been widely used to remove pesticide residues from fruits and vegetables and hormones from meat. Existing food purifiers generally include an ozone generator for producing ozone, and an ozone water generator connected to the ozone generator and used to mix ozone with water to form ozone water by immersion in water.

[0003] Existing ozone water generating devices generally include a shell formed by the joining of a bottom cover and a top cover, as well as an isolation hood, a gas diffuser plate, an impeller, a fixed plate, and a motor inside the shell. The motor is the core power component of the device, which is used to drive the impeller to rotate so as to stir and mix ozone and water to form ozone water. However, the motor in the ozone water generating device is relatively troublesome to install and has poor working stability, so there is room for improvement. Utility Model Content

[0022] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0023] This utility model discloses an ozone water generating device, such as... Figure 1 As shown, the device includes a housing consisting of a top cover 1, a guide ring 2, and a bottom cover 3, as well as a motor 4 and an impeller 5 disposed within the housing. The inner cavity of the housing is divided into an upper chamber and a lower chamber, which are distributed vertically. The motor 4 is installed in the sealed lower chamber, and its output shaft 41 passes through the upper chamber and is connected to the impeller 5 therein.

[0024] In this embodiment, the lower chamber for mounting the motor 4 is specifically as follows: Figure 1 and Figure 2 As shown, the device includes a bottom cover 3, a fixing plate 6, and a mounting plate 7. The lower surface of the fixing plate 6 has an annular groove around its outer edge, and a first sealing ring 14 is embedded in the annular groove. The upper surface of the bottom cover 3 has an annular rib 31 for embedding into the annular groove and abutting against the annular sealing ring. This allows the bottom cover 3 and the fixing plate 6 to form a sealed motor cavity C, in which the motor 4 is installed. At the same time, the fixing plate 6 has a through hole in its middle, through which the output shaft 41 of the motor 4 passes to the top of the fixing plate 6 and is sealed and connected to the through hole. The mounting plate 7 is connected to the fixing plate 6 and is located below the motor 4 to support the motor 4. This allows the motor 4 to be fixed on the fixing plate 6 as a whole, thereby facilitating the installation between the fixing plate 6 and the bottom cover 3.

[0025] In this embodiment, specifically as follows: Figure 2As shown, a bushing 8 is embedded in the through hole of the fixing plate 6. The bushing 8 is provided with a pressing edge 81 for pressing against the fixing plate 6. A nut 82 is threadedly connected to the part of the bushing 8 that extends to the lower part of the fixing plate 6. The bushing 8 is fixed in place by tightening the nut 82 and engaging with the pressing edge 81. The output shaft 41 of the motor 4 passes through the bushing 8, and an oil seal 11 and at least one first bearing 12 are arranged sequentially from top to bottom between the bushing 8 and the output shaft 41. The oil seal 11 and at least one first bearing 12 are tightly connected between the bushing 8 and the motor 4. The oil seal 11 and at least one first bearing 12 are clamped between the bushing 8 and the motor 4 by upper and lower limits. The output shaft 41 of the motor 4 extends to the top of the fixing plate 6 after passing through the inner ring of at least one first bearing 12 and the inner hole of the oil seal 11. This not only ensures the sealing fit between the output shaft 41 of the motor 4 and the fixing plate 6, but also achieves the upper constraint of the motor 4. Preferably, there are two first bearings 12, which can effectively ensure the rotational concentricity of the output shaft 41 of the motor 4.

[0026] In this embodiment, as Figure 2 As shown, the fixing plate 6 is provided with several connecting posts 61 on the outer periphery of the motor 4. The mounting plate 7 is fixedly connected to the connecting posts 61 by screws so that the mounting plate 7 is located below the motor 4 to support the motor 4. Preferably, there are four connecting posts 61, which are respectively located at the four corners of the mounting plate 7. At the same time, in order to improve the installation stability of the motor 4 on the mounting plate 7, the bottom of the motor 4 is preferably provided with a notch, and a second bearing 13 is fixedly embedded in the notch. The mounting plate 7 is provided with corresponding insertion protrusions 71 for inserting into the inner ring of the second bearing 13 to form a stable fit, thus achieving the lower constraint of the motor 4.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the lower chamber also includes a gas diffuser plate 10, which is annular in shape and rests on a fixed plate 6 with its inner hole facing the through hole. The gas diffuser plate 10 and the fixed plate 6 are arranged with a gap to form a gas diffusion cavity. A U-shaped sealing ring 15 is fitted on the inner edge of the gas diffuser plate 10. The pressing edge 81 of the bushing 8 presses against the U-shaped sealing ring 15 and cooperates with the fixed plate 6 to clamp and fix the inner end of the gas diffuser plate 10 and the U-shaped sealing ring 15. This also ensures the sealing effect between the bushing 8, the gas diffuser plate 10 and the fixed plate 6, ensuring the sealing performance of the motor cavity C and the safety of the internal motor 4.

[0028] In this embodiment, as Figure 1As shown, the lower chamber also includes a ring-shaped pressure plate 9, whose sealing buckle is located between the fixing plate 6 and the bottom cover 3 to form a sealed isolation cavity D. This isolation cavity D is arranged around the outside of the motor cavity C, thus creating a sealed defense line outside the motor cavity C, effectively improving the waterproof performance of the motor cavity C and ensuring the working stability of the motor 4. Specifically, the upper surface of the bottom cover 3 has an annular groove corresponding to its outer edge, and a second sealing ring 16 is embedded in the annular groove. The outer edge of the pressure plate 9 has an external pressure head 92 that presses against the second sealing ring 16. This achieves a sealed connection between the outer edge of the pressure plate 9 and the bottom cover 3; the fixing plate 6 has an annular groove corresponding to its outer edge, and an L-shaped sealing ring 17 is embedded in the annular groove. The outer edge of the gas diffuser plate 10 presses on the transverse part of the L-shaped sealing ring 17. The inner edge of the pressure plate 9 has an inner pressure head 91 that presses against the gas diffuser plate 10 and cooperates with the vertical part of the L-shaped sealing ring 17. This achieves a sealed connection between the pressure plate 9, the fixing plate 6 and the gas diffuser plate 10; at the same time, the gas diffuser plate 10 can be easily pressed onto the fixing plate 6 by the action of the pressure plate 9 and the bushing 8.

[0029] Compared with the prior art, this utility model has a simple and reasonable structure. The motor is constrained to the fixed plate by the cooperation of the mounting plate and the bushing, which makes the installation of the motor simpler and more stable. At the same time, the motor and the fixed plate become a whole, which greatly simplifies the installation between the fixed plate and the bottom cover. Furthermore, by forming a double-cavity structure of a sealed isolation cavity and a motor cavity, two sealing defenses are effectively formed, which greatly improves the safety of the motor.

[0030] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
