Description

Technical Field

[0001] This utility model relates to a handheld negative ion respirator for improving the negative ion content in the air during human respiration. Background Technology

[0002] Negative ions, known as "air vitamins," offer significant health benefits. They also play a multifaceted role in the medical field.

[0003] The negative ion generator consists of a switching power supply and a high-voltage discharge emitter. The high-voltage discharge emitter discharges in space to generate negative ions in the air.

[0004] In existing technologies, the negative ions generated by the high-voltage discharge transmitter in space are released into the space by the action of a fan and are diluted by the air in the space. People can only breathe the negative ions diluted by the air in a specific space, which has poor effect. Moreover, the negative ion generator is bulky and cannot be carried around or used by individuals. Utility Model Content

[0005] To address the issues of large size, low negative ion content, and inability to meet the needs of individuals for convenient and portable negative ion breathing in existing negative ion generators, this utility model discloses a handheld negative ion respirator.

[0006] Piezoelectric miniature air pumps have advantages such as stable air pressure, small size, high efficiency, low noise and low power consumption, and have been widely used in environments where small size, high efficiency and high noise requirements are required.

The pressure gas generating chamber and the negative ion 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 negative ion generating chamber is provided with a negative ion exhaust port.

[0011] A ceramic piezoelectric vibrator is installed inside the pressure gas generating chamber.

[0012] A negative ion generator is fixedly supported inside the negative ion generating chamber.

[0013] The pressure chamber pump cover is fixedly connected to the pressure gas generating chamber on the pump body, forming a closed pressure gas generating chamber structure.

[0014] The generating chamber pump cover is fixedly connected to the negative ion generating chamber on the pump body to form a closed negative ion generating chamber structure. The negative ion exhaust port is set on the generating chamber pump cover and is connected to the breathing mask.

[0015] The air inlet control valve is connected to the atmosphere via the air inlet.

[0016] The advantages of this utility model are: simple structure, convenient to use and carry, low cost, high efficiency in producing negative ions in the negative ion generation chamber of the air pump, high negative ion content in the air outlet, and low power consumption.

[0021] Referring to the attached drawings, a handheld negative ion respirator includes: a housing 1, a breathing mask 2, a negative ion generating pump 3, a control circuit 4, and a power supply 5. The negative ion generating pump 3, the control circuit 4, and the power supply 5 are disposed inside the housing 1, and the breathing mask 2 is disposed on the air outlet 1-1 of the housing 1.

[0022] The negative ion generating pump 3 includes: a pump body 31, an outlet control valve 32, an inlet control valve 33, an exhaust port 34, a ceramic piezoelectric vibrator 35, a negative ion generator 36, a pressure chamber pump cover 37, a generating chamber pump cover 38, and an inlet 39.

[0023] The pump body 31 has a dual-chamber structure consisting of a pressure gas generating chamber 31-1 and a negative ion generating chamber 31-2. The pressure gas generating chamber 31-1 and the negative ion generating chamber 31-2 are connected by an outlet control valve 32. The pressure gas generating chamber 31-1 is connected to the atmosphere through an inlet control valve 33 and an inlet 39. The negative ion generating chamber 31-2 is provided with a negative ion exhaust port 34.

[0024] A ceramic piezoelectric vibrator 35 is provided inside the pressure gas generating chamber 31-1.

[0025] A negative ion generator 36 is fixedly supported inside the negative ion generating chamber 31-2.

[0026] The pressure chamber pump cover 37 is fixedly connected to the pressure gas generating chamber 31-1 on the pump body 31, forming a closed pressure gas generating chamber 31-1 structure.

[0027] The generating chamber pump cover 38 is fixedly connected to the negative ion generating chamber 31-2 on the pump body 31, forming a closed negative ion generating chamber 31-1 structure. The negative ion exhaust port 34 is provided on the generating chamber pump cover 38 and is connected to the breathing mask 2.

[0028] When this invention is in operation, the ceramic piezoelectric vibrator 35 vibrates, drawing air into the pressurized gas generating chamber 31-1 through the air inlet 39 and the air inlet control valve 33. The pressurized air generated in the pressurized gas generating chamber 31-1 enters the negative ion generating chamber 31-2 through the air outlet control valve 32. The high-voltage discharge emitter of the negative ion generator 36 ionizes the air in the negative ion generating chamber 31-2, producing negative ions in the pressurized air. The pressurized air in the closed negative ion generating chamber 31-2 further enhances the negative ion ionization efficiency. The pressurized air carrying negative ions enters the breathing mask 2 through the exhaust port 34, allowing the user to breathe negative ions through their mouth and nose on the breathing mask 2.

[0029] During the use of this invention, the pressurized air carrying negative ions has less contact with the atmosphere, thus ensuring the negative ion content in the pressurized air and reducing its outward diffusion.

[0030] In this embodiment of the utility model, in order to keep the air clean, an air filter 310 is provided at the inlet end of the air inlet 39.

[0031] In this embodiment of the invention, for ease of operation, a display screen 311 is also provided on the housing 1, and the display screen 311 is electrically connected to the control circuit 4. During operation, the invention can be controlled via the display screen 311 or the control buttons 7.
