Description

Technical Field

[0001] This utility model relates to household ornamental aquatic plant cultivation equipment, and in particular to a pneumatic electric pump that integrates ozone for water sterilization, disinfection, water purification and oxygen supply, and has water purification and deodorization functions. Background Technology

[0002] The use of ozone for water sterilization, disinfection, and water purification in existing technologies is widely used in environmental water treatment. Ozone generation is based on the corona discharge method, where air is ionized to generate ozone. An ozone generator consists of a generator board, a control circuit, and an ozone generator board. The control circuit controls the ozone generator board to work, and after air flows through the ozone generator board, some of the air generates ozone.

[0003] In existing technologies for home aquatic plant cultivation, especially ornamental fish cultivation equipment, air pumps are essential for supplying oxygen to the water. However, there is a lack of small, easy-to-use integrated devices that can achieve a reasonable and precise match between the pressure, stability, and flow rate of pressurized air and the amount of ozone generated, while simultaneously using ozone to sterilize, disinfect, and purify the water.

[0004] If an ozone generator is set up independently to achieve the purpose of water sterilization, disinfection, and water purification, an air pump needs to be connected to the air inlet of the ozone generator. The disadvantage of the existing technology of selecting different air pumps to connect to the ozone generator is that, because ozone is extremely unstable, it is impossible to achieve a reasonable and precise match between the pressure, pressure stability, and flow rate of the air generated by the air pump and the ozone generator.

[0005] The existing technology uses an air pump to deliver ozone to the aquarium water via an ozone generator. However, this technology has drawbacks such as complex structure, large size and noise, difficulty in matching the air pump with the ozone generator, low ozone generation efficiency, low ozone concentration in the gas, high power consumption, and inability to achieve intermittent ozone generation and individual oxygen supply. Utility Model Content

[0006] To address the shortcomings of existing technologies, such as complex structure, large size and noise, difficulty in matching the air pump with the ozone generator resulting in low ozone generation efficiency, low ozone concentration in the gas, high power consumption, and inability to achieve intermittent ozone generation and independent oxygen supply, this utility model discloses a piezoelectric pump with water purification and deodorization functions.

The pressure gas generating chamber and the ozone generating chamber are connected by an outlet control valve. The pressure gas generating chamber is connected to the atmosphere by an inlet control valve. The ozone generating chamber is provided with a pressure ozone exhaust port, which is connected to the fish tank through an exhaust pipe.

[0011] The ceramic piezoelectric vibrator is placed inside the pressure gas generating chamber, forming part of the piezoelectric pump structure.

[0012] The ozone generating part includes an ozone generating plate, which is disposed inside the ozone generating cavity.

[0024] Referring to the attached figure, a piezoelectric pump with water purification and deodorization functions includes: a housing part, a piezoelectric pump part, an air pump mounting part, an ozone generating part, and an electrical control circuit part.

[0025] The piezoelectric pump section includes: a pump housing 1-1, a ceramic piezoelectric vibrator 1-2, a pump upper cover 1-3, a pump lower cover 1-4, an inlet control valve 1-5, and an outlet control valve 1-6.

[0026] The air pump housing 1-1 is sealed and connected to the air pump upper cover 1-3 and the air pump lower cover 1-4 respectively, forming a dual-chamber structure of the pneumatic electric pump part, namely the pressure gas generating chamber 1-11 and the ozone generating chamber 1-12. The pressure gas generating chamber 1-11 and the ozone generating chamber 1-12 are connected through the outlet control valve 1-6. The pressure gas generating chamber 1-11 is connected to the atmosphere through the inlet control valve 1-5. The ozone generating chamber 1-12 is provided with a pressure ozone exhaust port 2, which is connected to the fish tank 4 through the exhaust pipe 3.

[0027] The ceramic piezoelectric vibrator 1-2 is installed in the pressure gas generating chamber 1-11, forming part of the piezoelectric pump structure.

[0028] The ozone generating part includes an ozone generating plate 2-1, which is disposed inside the ozone generating chamber 1-12.

[0029] The piezoelectric pump is installed inside the housing 5 of the housing part, and the housing 5 of the housing part is provided with an air inlet 5-1 that communicates with the air inlet control valve 1-5 of the piezoelectric pump part.

[0030] The control circuit board 6 of the electric pump and the electric control circuit is located inside the housing 5 of the housing part, and the air pump mounting part is located outside the housing 5 of the housing part.

[0031] The high-frequency vibration of the ceramic piezoelectric vibrator 1-2 in this invention generates pressurized air in the pressurized gas generating chamber 1-11, which then enters the ozone generating chamber 1-12 through the outlet control valve 1-6.

[0032] Pressurized air passes through ozone generator plate 2-1 in ozone generation chamber 1-12 to generate ozone, and then enters the water in fish tank 4 through pressure ozone exhaust port 2 and exhaust pipe 3 to carry out water sterilization, disinfection, water purification and oxygenation in fish tank 4.

[0033] The pressure, stability, and flow rate of the pressurized gas generated by the pressurized gas generation chamber 1-1 are precisely matched with the ozone generator 2-1 to achieve high efficiency in ozone generation from the flowing pressurized gas and increase the ozone density in the pressurized gas. Simultaneously, the ozone generator 2-1 is controlled to operate on a timed basis, providing ozone to the water body at regular intervals while ensuring uninterrupted oxygen supply, thus mitigating the harm of excessive ozone to aquatic plants.

[0034] To facilitate installation, the air pump mounting component is either a hook 7-1 or a negative pressure suction cup 7-2. This hook 7-1 or suction cup 7-2 securely mounts the air pump to the fish tank 4, minimizing space usage.

[0035] To facilitate control, the outer side of the housing 5 of this invention is equipped with control buttons 6-1 or a touch display control screen on the control circuit board 6. This enables precise timed or quantitative control of ozone.

[0036] To address the noise and noise transmission issues of this invention, a shock-absorbing pad 8 is provided between the piezoelectric pump section and the housing 5 located in the housing section.

[0037] In this embodiment of the invention, the electronic control circuit includes: a switching power supply, a main control circuit, a display circuit, an air pump drive circuit, and an ozone drive circuit. The switching power supply is electrically connected to the display circuit, the air pump drive circuit, and the ozone drive circuit via the main control circuit board. This enables precise timing or quantitative control of ozone.

[0038] A fruit and vegetable washing machine with ozone function includes: an electronic control circuit, a washing machine housing, a washing basin, and an ozone generator. The electronic control circuit controls the ozone generator to deliver ozone to the washing water in the washing basin.

[0039] The ozone generator mentioned is an air pump type ozone generator 1.

[0040] The air pump type ozone generator 1 includes: generator electrical control circuit, generator housing 1-1, ceramic piezoelectric vibrator 1-2, housing upper cover 1-3, housing lower cover 1-4, air inlet control valve 1-5, air outlet control valve 1-6, and ozone generating plate 2.

The pressure gas generating chamber 1-11 and the ozone generating chamber 1-12 are connected by an outlet control valve 1-6. The pressure gas generating chamber 1-11 is connected to the atmosphere by an inlet control valve 1-5. The ozone generating chamber 1-12 is provided with an ozone exhaust port 3.

[0042] The ceramic piezoelectric vibrator 1-2 is installed in the pressure gas generation chamber 1-11 to form a piezoelectric pump structure.

[0043] The ozone generator 2 is disposed inside the ozone generating chamber 1-12.

[0044] The ozone exhaust port 3 of the air pump ozone generator 1 is connected to the inner cavity of the cleaning basin 4 via a pipeline.

[0045] The high-frequency vibration of the ceramic piezoelectric vibrator 5 in this invention generates pressurized air in the pressurized gas generating chamber 1-1, which then enters the ozone generating chamber 1-12 via the outlet control valve 1-6.

[0046] Pressurized air passes through ozone generating plate 2 in ozone generating chamber 1-12 to generate ozone, and then outputs it through ozone exhaust port 3 into the water in washing basin 4 to clean, sterilize and remove pesticide residues from fruits and vegetables in washing basin 4.

[0047] Based on the design of the pressure of the pressure generated by the pressure gas generating chamber 1-1, the pressure stability and flow rate of the pressure gas are reasonably and accurately matched with the ozone generating plate 2, so as to achieve high efficiency of ozone generation in the flowing pressure gas and increase the ozone density in the pressure gas.

[0048] In this embodiment of the invention, a vortex-generating water pump 5 is also included, which is disposed at the edge of the washing basin 4. The vortex-generating water pump 5 causes the water in the washing basin 4 to form a swirling water flow dynamic, thereby achieving uniform combination of ozone and water and fully utilizing the function of ozone.

[0049] In this embodiment of the utility model, in order to ensure that ozone combines with water more quickly and evenly, the air pump ozone generator 1 is installed inside the vegetable washing machine housing 6, and the ozone exhaust port 3 of the air pump ozone generator 1 is connected to the washing basin 4 via the air plate 7.
