The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The ion generating device and the vehicle proposed in the embodiment of the utility model are described below with reference to the accompanying drawings.

[0025] Figure 1 is a schematic diagram of the structure of an ion generating device according to an embodiment of the utility model, referring to Figure 1 As shown, the device 100 includes: a first power supply circuit 110 , a first ion generator 120 , a second ion generator 130 and a condenser 140 .

[0026] Among them, the first power supply circuit 110 is connected to the DC power supply VDD, and is configured to convert the first DC power output by the DC power supply VDD into a first AC power; the first ion generator 120, the first ion generator 120 is connected to the first power supply circuit 110, and is configured to ionize the surrounding air based on the first AC power to generate negative ions; the second ion generator 130 and the condenser 140, the second ion generator 130 and the condenser 140 are respectively connected to the first power supply circuit 110, the condenser 140 is configured to generate condensed water on the surface of the second ion generator 130 based on the first AC power, and the second ion generator 130 is configured to ionize the condensed water based on the first AC power to generate water ions.

[0027] Specifically, the first power supply circuit 110 can be a variety of inverter circuits, such as a full-bridge inverter circuit, etc. The specific principle of the inverter circuit is not expanded here. The first power supply circuit 110 can convert the first direct current into the first alternating current to power the first ion generator 120, the second ion generator 130 and the condenser 140. Among them, the first ion generator 120 can ionize the surrounding air based on the first alternating current to generate negative ions to generate negative ions. In the second ion generator 130 and the condenser 140, the condenser 140 can first generate condensed water on the surface of the second ion generator 130 based on the first alternating current, and then the second ion generator 130 ionizes the condensed water on the surface based on the first alternating current to generate water ions, thereby enabling the device 100 to release water ions and negative ions into the air, and the water ions and negative ions in the air can play the role of air purification, sterilization, moisturizing the skin, and removing odors, and compared with a single negative ion generator or a water ion generator, the air purification effect of the device 100 of the utility model embodiment is better. At the same time, compared to the solution of separately providing a negative ion generator and a water ion generator, the device 100 of the embodiment of the utility model can not only integrate the two generators into one device to reduce hardware costs and occupied space, but also the first ion generator 120, the second ion generator 130 and the condenser 140 in the device 100 can also share the first power supply circuit 110. Therefore, the device 100 of the embodiment of the utility model can also effectively reduce the hardware cost of the device 100.

[0028] In the above embodiment, the first direct current output by the DC power supply is converted into a first alternating current through an internally arranged first power supply circuit, and is provided to the first ion generator, the second ion generator and the condenser, so that the first ion generator ionizes the surrounding air to generate negative ions, and the second ion generator and the condenser cooperate to generate water ions, thereby enabling the device to have the function of generating water ions and negative ions, with a better air purification effect, while also being able to save hardware costs, thereby effectively improving the user experience and economy of the device.

[0029] In some embodiments, reference Figure 2 As shown, the first ion generator 120 includes: a first voltage module 121, a first electrode 122 and a discharge ring 123. The first voltage module 121 is connected to the first power supply circuit 110 and the first electrode 122 respectively, and the discharge ring 123 is grounded GND. The first voltage module 121 is configured to output a first negative high voltage to the first electrode 122 based on a first alternating current, so that the first electrode 122 discharges to the discharge ring 123 to ionize the surrounding air to generate negative ions.

[0030] Specifically, the first voltage module 121 can be a variety of pulse generating circuits, etc., to generate a first negative high voltage based on the first alternating current. The specific circuit and principle are not expanded here. The first electrode 122 and the discharge ring 123 can be set in a relatively fixed position. For example, the first electrode 122 and the discharge ring 123 can be fixed on the same circuit board, and in order to improve the air ionization effect, the first electrode 122 can be coaxially arranged with the discharge ring 123. When the first ion generator 120 is running, the first voltage module 121 can output a negative high voltage to the first electrode 122 based on the first alternating current. Since the discharge ring 123 is grounded GND, the first electrode 122 can discharge the discharge ring 123 to ionize the air between the first electrode 122 and the discharge ring 123, thereby generating negative ions. In this way, the negative ion generation function of the first ion generator is realized.

[0031] In some embodiments, reference Figure 3 As shown, the second ion generator 130 includes: a second voltage module 131, a second electrode 132 and a third electrode 133, the second voltage module 131 is respectively connected to the first power supply circuit 110 and the second electrode 132, and the third electrode 133 is grounded GND; wherein, the condenser 140 is configured to cool the second electrode 132 to generate condensed water on the surface of the second electrode 132, and the second voltage module 131 is configured to output a second negative high voltage to the second electrode 132 based on the first alternating current, so that the second electrode 132 discharges to the third electrode 133 to ionize the condensed water to generate water ions.

[0032] Specifically, the second voltage module 131 may be a pulse generating circuit identical to the first voltage module 121, so as to output a negative high voltage to the second electrode 132 based on the first alternating current, which will not be described in detail here. The condenser may be a variety of heat exchange circuits to cool the second electrode 132 to generate condensed water, the second electrode 132 may be an atomizing electrode, and the third electrode 133 may be an annular electrode arranged in the circumference of the second electrode 132, so that the second electrode 132 can discharge to the third electrode 133 based on the second negative high voltage to ionize the condensed water. When the second ion generator 130 is running, the second voltage module 132 may output a second negative high voltage to the second electrode 132 based on the first alternating current, and at the same time, the condenser 140 may cool the second electrode 132 to generate condensed water on the surface of the second electrode 132, and then the second electrode 132 may discharge to the third electrode 133 to ionize the condensed water on the surface of the second electrode 132 to generate water ions.

[0033] Optional, reference Figure 4As shown, the device 100 also includes: a temperature control module 150 and a heat dissipation module 160. The temperature control module 150 is respectively connected to the heat exchange end 141 of the condenser 140 and the heat dissipation module 160. The temperature control module 150 is configured to obtain the temperature of the heat exchange end 141 and control the heat dissipation module 160 according to the temperature of the heat exchange end 141 to dissipate heat from the condenser 140.

[0034] Specifically, during the operation of the condenser 140, the condenser 140 needs to transfer the heat at the second electrode 132 end to the heat exchange end 141 of the condenser 140 through the refrigerant to achieve the cooling function of the second electrode 132. Therefore, the heat exchange end of the condenser 140 will have a heat accumulation problem, especially when the device 100 needs to be used in a small space scene such as a vehicle, the heat accumulation will be more serious. The heat accumulation problem of the heat exchange end 140 will affect the cooling effect of the second electrode 132, and then affect the efficiency of the device 100 in generating water ions. Therefore, in the embodiment of the utility model, the device 100 also has a temperature control module 150 and a heat dissipation module 160, wherein the temperature control module 150 can be a TEC (ThermoElectricCooler, temperature controlled electric cooler) chip, and the heat dissipation module 160 can include a variety of heat dissipation circuits, for example, the heat dissipation module 160 can include a fan and its drive circuit, which is not limited here. When the condenser 140 is working, the temperature control module 150 can detect the temperature of the heat exchange end 141 of the condenser 140, and when the temperature of the heat exchange end 141 exceeds the preset temperature, the heat dissipation module 160 is controlled to dissipate the heat of the heat exchange end 141 of the condenser 140, thereby avoiding possible heat accumulation problems, enabling the device 100 to stably generate water ions, and thereby improving the reliability of the device.

[0035] In some embodiments, reference Figure 4 As shown, the device 100 also includes: a second power supply circuit 170, which is respectively connected to the DC power supply VDD, the temperature control module 150 and the heat dissipation module 160, and is configured to convert the first DC power output by the DC power supply VDD into a second DC power, and provide it to the temperature control module 150 and the heat dissipation module 160.

[0036] Specifically, since the temperature control module 150 and the heat dissipation module 160 can be a variety of integrated chips, they usually require stable DC low-voltage power supply. Therefore, the device 100 also has a second power supply circuit 170. The second power supply circuit 170 can convert the first DC power output by the DC power supply VDD into a second DC power to supply the temperature control module 150 and the heat dissipation module 160. The second power supply circuit 170 can be a conventional BUCK, BOOST circuit, etc., which will not be expanded here.

[0037] In some embodiments, reference Figure 4As shown, the device 100 also includes: a controller 180, which is connected to the first power supply circuit 110 and the second power supply circuit 170 respectively, and is configured to control the first power supply circuit 110 to convert the first direct current into the first alternating current, and to control the second power supply circuit 170 to convert the first direct current into the second direct current.

[0038] Specifically, refer to Figure 4 As shown, the controller 180 is mainly used to output enable signals and drive signals to the switch devices in the first power supply circuit 110 and the second power supply circuit 170 to control the first power supply circuit 110 to convert the first direct current into the first alternating current, and to control the second power supply circuit 170 to convert the first direct current into the second direct current. The specific principle is not elaborated here. Figure 5 As shown, the DC power source VDD may be connected to the controller 180 to output a first DC power to power the controller 180 .

[0039] Furthermore, the device 100 also includes: a voltage sampling circuit 190, which is respectively connected to the controller 180 and the first power supply circuit 110, and is configured to sample the first alternating current to generate a voltage sampling signal. The controller 180 is also configured to control the first power supply circuit 110 to convert the first direct current into the first alternating current based on the voltage sampling signal.

[0040] Specifically, refer to Figure 2 As shown, the controller 180 can generate a corresponding drive signal according to the voltage sampling signal output by the voltage sampling circuit 190 to control the first power supply circuit 110 to convert the first direct current into the first alternating current, thereby realizing closed-loop control of the first power supply circuit 110 to ensure the stability of the first alternating current; alternatively, the controller 180 can also determine the size of the first alternating current through the detected voltage sampling signal. When it is determined that the first alternating current is too large or too small, the controller 180 stops outputting the enable signal to the first power supply circuit 110 to realize over-voltage and under-voltage protection for the first power supply circuit 110, thereby improving the stability and safety of the device.

[0041] Furthermore, the apparatus 100 further includes: a signal transceiver 1100 , which is connected to the controller 180 , and is configured to receive and send communication signals between the controller 180 and the external device 200 .

[0042] Specifically, the signal transceiver 1100 is mainly used to receive and send communication signals between the controller 180 and external devices, so that the controller 180 can communicate with the external device, so that the external device 200 can obtain the working status of the device 100, and control the operation of the controller 180, thereby improving the convenience of the controller 180. Among them, the signal transceiver 1100 can adapt to a variety of communication protocols, such as LIN (Local Interconnect Network) communication, CAN, (Controller Area Network, controller area network bus), etc., to adapt to a variety of scenarios, which are not specifically limited here.

[0043] Furthermore, the device 100 also includes: a filtering circuit 1110 and a voltage stabilizing circuit 1120, the filtering circuit 1110 is connected to the DC power supply VDD and the voltage stabilizing circuit 1120 respectively, and the voltage stabilizing circuit 1120 is also connected to the controller 180, the first power supply circuit 110 and the second power supply circuit 170, wherein the filtering circuit 1110 is configured to filter the first DC power, and the voltage stabilizing circuit 1120 is configured to stabilize the first DC power after filtering.

[0044] Specifically, refer to Figure 2 As shown, the filter circuit 1110 and the voltage stabilizing circuit 1120 are mainly used to filter and stabilize the first direct current to improve the power supply quality of the first direct current. Among them, the filter circuit 1110 can be a full-bridge, half-bridge filter circuit, etc., and the stabilizing voltage can be a capacitor, an LDO (Low Dropout Regulator, low voltage difference regulator) module, etc., which are not specifically limited here. At the same time, the filter circuit 1110 and the voltage stabilizing circuit 1120 can also prevent the device 100 from generating harmonics that affect the direct current power supply VDD, thereby improving the reliability and EMC (Electro Magnetic Compatibility, electromagnetic compatibility) performance of the device 100.

[0045] Optionally, in order to ensure that the device 100 can stably release water ions and negative ions, the device 100 may have two independent air vents, and the two electrodes of the first electrode and the second electrode are placed in the corresponding independent air vents to avoid mutual interference in the release processes of water ions and negative ions, thereby improving the stability of the device 100.
