Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically providing a negative ion generator. Background Technology

[0002] Air conditioners typically regulate indoor temperature by exchanging heat between indoor air and an indoor heat exchanger. During operation, to save energy and quickly reach the preset temperature, doors and windows are usually closed. However, over time, the concentration of bacteria and particulate matter in the indoor air gradually increases, leading to a decrease in indoor air quality. To address this, people often equip air conditioners with health modules, which may include sterilization, PM2.5 removal, oxygenation, and negative ion generation modules.

[0003] However, users usually cannot intuitively perceive the operation of these health modules, and each health module itself usually does not have a window configured so that users can intuitively perceive its operation, which is not conducive to the sales of products with health modules.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0006] This utility model provides a negative ion generator, which includes a housing and a negative ion generating component and a light-emitting component disposed within the housing. The housing is provided with a ventilation structure. The negative ion generating component is used to generate negative ions. The light-emitting component is disposed on the side of the negative ion generating component, and at least a portion of the light-emitting component is aligned with the housing so that the light emitted by the light-emitting component can illuminate the housing when the negative ion generating component is in operation.

[0007] In the preferred embodiment of the above-mentioned negative ion generator, the negative ion generator includes multiple sets of negative ion generating components, at least a portion of the negative ion generating components are arranged along the length direction of the housing, and the light-emitting component is disposed between at least one pair of adjacent sets of negative ion generating components.

[0008] In the preferred embodiment of the above-mentioned negative ion generator, the light-emitting component is disposed between two sets of negative ion generating components arranged along the length direction of the housing.

[0009] In the preferred embodiment of the above-mentioned negative ion generator, the housing is provided with a light-transmitting member at a position corresponding to the light-emitting member, and the light-transmitting member is configured to allow light emitted by the light-emitting member to pass through.

[0012] In the preferred embodiment of the above-mentioned negative ion generator, the light-transmitting component is provided with an indicator so as to display the function of the negative ion generator when the light-emitting component transmits light.

[0013] In the preferred embodiment of the above-mentioned negative ion generator, the negative ion generating component includes multiple electrodes, at least a portion of which are arranged along the length of the housing, and each electrode is electrically connected to a negative voltage.

[0014] In the preferred technical solution of the above negative ion generator, the distance between two adjacent electrodes is greater than or equal to 1.5cm.

[0015] In the preferred embodiment of the above-described negative ion generator, the plurality of electrodes may be the same or different; and / or

[0016] The electrode is one of the following: carbon brush, needle, or tungsten wire.

[0017] In this invention, the negative ion generator includes a housing and a negative ion generating component and a light-emitting component disposed within the housing. The housing has a ventilation structure. The negative ion generating component generates negative ions, and the light-emitting component is disposed on the side of the negative ion generating component, with at least a portion aligned with the housing. This allows the light emitted by the light-emitting component to illuminate the housing when the negative ion generating component is running. Thus, when the negative ion generating component is powered on, air enters the housing through the ventilation structure, is ionized by the negative ion generating component, and generates negative ions. These negative ions are carried by the air through the ventilation structure to the outside of the housing, where they sterilize and remove dust, improving air quality and contributing to the user's health. Simultaneously, the user can accurately and intuitively observe the operation of the health module's negative ion generator through the light emitted by the light-emitting component, directly perceiving the presence of the negative ion function.

[0019] Furthermore, the negative ion generating component includes multiple electrodes, at least a portion of which are arranged along the length of the housing, and each electrode is electrically connected to a negative voltage. This allows it to cover a larger area, ensuring that air flowing through the negative ion generator can fully contact and ionize the electrodes, producing a sufficient number of negative ions to better improve the air quality in the space it occupies.

[0027] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that although this embodiment uses a negative ion generator installed on a wall-mounted air conditioner as an example, the negative ion generator can obviously also be installed on a cabinet air conditioner, central air conditioner, ducted air conditioner, or other types of air conditioners, or on an air purifier, sterilizer, or other types of air handling equipment.

[0028] It should be noted that in the description of this utility model, the terms "inner", "outer", "left", "right", "center", "middle", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0029] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Currently, users typically cannot intuitively perceive the operation of the health modules installed on air conditioners, and each health module itself usually lacks a window allowing users to visually experience its operation, which hinders the sales of products equipped with health modules. Therefore, the negative ion generator of this application includes not only a negative ion generating component capable of producing negative ions but also a light-emitting component. The light emitted by this component allows users to intuitively perceive the operation of the negative ion generator within the health module, effectively improving the user experience and promoting product sales.

[0031] The following is combined with Figures 1 to 4This paper will describe the possible implementation methods of the negative ion generator of this utility model.

[0032] In this application, the wall-mounted air conditioner includes a casing, a heat exchanger, and an indoor fan housed within the casing. The casing has an air inlet and an air outlet. Under the action of the indoor fan, indoor air enters the casing through the air inlet, exchanges heat with the heat exchanger, and then returns to the indoor space through the air outlet, thereby achieving the purpose of adjusting the indoor temperature. The negative ion generator 1 of this application is located near the left end of the air outlet. When assembled, the negative ion generator 1 extends along the length of the air outlet. When the air conditioner is running, a portion of the air flowing from the air outlet simultaneously flows through the negative ion generator 1, is ionized by the negative ion generator 1, generates negative ions, and then returns to the indoor space with the air, improving indoor air quality.

[0033] Obviously, the negative ion generator 1 can also be placed near the right end of the air outlet, or in the middle, or in other possible locations.

[0034] like Figures 1 to 3 As shown, the negative ion generator 1 includes a housing 11 and a negative ion generating component 12 and a light-emitting component 13 disposed within the housing 11. The housing 11 is a generally elongated hollow structure with an installation space formed therein, within which the negative ion generating component 12 and the light-emitting component 13 are disposed. A ventilation structure 14 is provided on the housing 11. When air flows through the negative ion generator 1, it can enter the housing 11 through the ventilation structure 14, be ionized by the negative ion generating component 12 to generate negative ions, and then return to the indoor space along with the air after passing through the ventilation structure 14, thus sterilizing and removing dust from the indoor space, improving the air quality in the space, and contributing to the user's health. The light-emitting component 13 is disposed on the side 1122 of the negative ion generating component 12, with at least a portion aligned with the housing 11. For example, the light-emitting component 13 can be a light strip, a light bead, or a light belt. The light-emitting component 13 is electrically connected to the negative ion generating component 12. When the negative ion generating component 12 is powered on, the light-emitting component 13 is illuminated, and the emitted light shines onto the housing 11, allowing the user to easily and intuitively see the operation of the negative ion generator 1. This design enables the wall-mounted air conditioner to ionize the air and generate negative ions, purifying the air and benefiting the user's health. It also allows users to intuitively perceive the presence of the negative ion function, effectively improving the user experience and promoting the sales of products with health-related features.

[0035] Obviously, the light-emitting component 13 may not be electrically connected to the negative ion generating component 12, but may be electrically connected to the power supply module of the negative ion generator 1. The negative ion generating component 12 is also electrically connected to the power supply module. When the negative ion generating component 12 is powered on, the light-emitting component 13 is also powered on and lit.

[0036] like Figures 1 to 3 As shown, the negative ion generator 1 includes multiple sets of negative ion generating components 12, at least some of which are arranged along the length of the housing 11. When the negative ion generator 1 is installed, the length of its housing 11 is approximately parallel to the length of the air outlet. This allows more air to enter the housing 11 through the ventilation structure 14, fully contacting and ionizing the multiple sets of negative ion generating components 12, generating more negative ions and improving the air quality of the indoor space. A light-emitting component 13 is positioned between two sets of negative ion generating components 12 arranged along the length of the housing 11. This ensures that the light emitted by the light-emitting component 13 can illuminate the housing 11, allowing the user to see the light emitted by the light-emitting component 13 when the negative ion generating components 12 are operating, thus visually observing the operation of the negative ion generating components 12 and intuitively perceiving the existence of the negative ion function. Obviously, the light-emitting component 13 can also be positioned between two sets of negative ion generating components 12 arranged along the width of the housing 11.

[0037] It should be noted that in this embodiment, the length direction of the housing 11 and the length direction of the air outlet are approximately as follows: Figure 1 In the horizontal direction, the width direction of the shell 11 is approximately... Figure 1 The direction perpendicular to the paper.

[0038] like Figures 1 to 4 As shown and in accordance with Figure 1 As shown in the diagram, the housing 11 includes a base 111 and a cover 112 that interlock with each other. The base 111 is generally rectangular in shape, and a mounting plate 1111 is provided on its upper side. The mounting plate 1111 is generally annular in shape distributed around the circumference of the base 111. Six locking blocks 1112, serving as mating structures, are provided on the outer wall of the mounting plate 1111, and the six locking blocks 1112 are located on the two long sides of the mounting plate 1111. The cover 112 includes a top 1121 and side portions 1122 extending downward around the top 1121. The top 1121 is generally rectangular in shape, and the top 1121 and the side portions 1122 form a generally inverted cover-like structure. Six slots 1123, capable of mating with the locking blocks 1112, are provided on the inner wall of the side portions 1122 of the cover 112. The cover 112 and the base 111 are interlocked through the mating connection of the locking blocks 1112 and the slots 1123.

[0039] It should be noted that the docking structure can also include five, four, three, or even fewer locking blocks 1112, or seven, eight, nine, or even more locking blocks 1112. Of course, the docking structure can also be other types of snap-fit ​​structures such as locking holes or slots 1123, as long as the base 111 and the cover 112 can be engaged with each other by snap-fit. Obviously, the cover 112 and the base 111 can also be engaged with each other by insertion, adhesion, magnetic adsorption, etc. Correspondingly, the docking structure can be a pin, Velcro, metal sheet, etc. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific method of engagement between the cover 112 and the base 111 according to the specific application scenario, as long as the engagement between the two can be achieved. Of course, the housing 11 can also only include the base 111.

[0040] Continue to refer to Figures 1 to 4The negative ion generator 1 includes two negative ion generating components 12, which are arranged on the base 111 along the length of the housing 11. A light-emitting component 13 is screwed or snapped between the two negative ion generating components 12, located near the inner wall of the mounting plate 1111, at the middle position along the length of the housing 11. In other words, the light-emitting component 13 is located at the middle of a long side near the base 111. The ventilation structure 14 includes multiple strip holes, six circular holes, V-shaped holes, and irregularly shaped holes. Some of the strip holes are located on the side 1122 of the housing 112, extending vertically. The remaining strip holes, six circular holes, V-shaped holes, and irregularly shaped holes are located on the top 1121 of the housing 112, forming two symmetrical patterns on the top 1121. Mounting holes 1124 are symmetrically arranged on the two long sides of the side portion 1122 of the housing 112. The mounting holes 1124 are roughly rectangular and are located approximately in the middle of the long side when viewed along the length of the housing 11. A recessed platform 1125 is formed around the mounting hole 1124. The light-transmitting member 15 is set at the recessed platform 1125 by snap-fit ​​or adhesive, thus positioning the light-transmitting member 15 in the middle of the long side of the housing 112. When the housing 112 and the base 111 are fastened together, the light-transmitting member 15 is positioned corresponding to the light-emitting member 13. Thus, when the negative ion generating component 12 is running, the light emitted by the light-emitting member 13 can directly illuminate and pass through the light-transmitting member 15, allowing the user to more intuitively see the operation of the negative ion generator 1 and perceive the presence of the negative ion function. Furthermore, when the negative ion generator 1 is installed at the outlet of the wall-mounted air conditioner, and its casing 11 extends along the length of the air outlet, the light-transmitting component 15 faces the user. This makes it easier for the user to see the operation of the negative ion generator 1 and to perceive the negative ion function more intuitively. It should be noted that the inner wall of the mounting plate 1111 is relative to the outer wall of the casing 11. The inner wall of the mounting plate 1111 refers to the side wall of the mounting plate 1111 that is away from the outer wall of the casing 11.

[0041] It should be noted that the light-transmitting component 15 can be made of transparent materials such as glass, plastics (such as acrylic, polycarbonate, polystyrene, etc.), or transparent ceramics, transparent resins, etc.

[0042] It should be noted that the light-transmitting component 15 may not be provided on the housing 11, and the user can still see the light emitted by the light-emitting component 13 through the ventilation structure 14 on the housing 112.

[0043] Continue to refer to Figures 1 to 3The light-transmitting component 15 is provided with a label, which is a text label, such as "clean" or "negative ions". When the light emitted by the light-emitting component 13 shines on the light-transmitting component 15, the text label can more intuitively demonstrate the negative ion function of the negative ion generator 1 to the user. Of course, the label can also be a graphic label or other type of label, as long as it can help the user intuitively feel the negative ion function.

[0044] like Figures 1 to 3 As shown and in accordance with Figure 1 As shown, the negative ion generating component 12 includes a mounting base 121 and three electrodes 122 disposed on the mounting base 121. The mounting base 121 is generally elongated and sits on the base 111. The three electrodes 122 are arranged along the length of the housing 11, and each electrode 122 is electrically connected to a negative voltage. In this way, each negative ion generating component 12 can cover a large area, and when air flows through the negative ion generator 1, it can fully contact and be ionized with each electrode 122, generating a sufficient number of negative ions to better improve the air quality in the space it is in.

[0045] It should be noted that the negative ion generating component 12 may also include two, one, or fewer electrodes 122, or even four, five, or more electrodes 122. When the negative ion generating component 12 includes multiple electrodes 122, the multiple electrodes 122 may all be arranged along the length direction of the housing 11, or they may be partially arranged along the length direction of the housing 11 and partially arranged along the width direction of the housing 11. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific number and arrangement of the electrodes 122 according to the specific application scenario, as long as they can ionize the air to generate a sufficient number of negative ions.

[0046] It should be noted that the power supply module of the negative ion generator 1 is equipped with a high-voltage power conversion section. Its function is to process the input DC or AC power through the EMI processing circuit and the lightning protection circuit, and then through the pulse oscillation circuit, overvoltage current limiting, high and low voltage isolation circuit, etc., to raise the low voltage to high voltage. Then, after rectification and filtering by special grade electronic materials, pure DC negative high voltage and DC positive high voltage are obtained. Finally, the DC negative high voltage is connected to each electrode 122 through the power supply wire.

[0047] Continue to refer to Figures 1 to 3 The distance between each pair of the three electrodes 122 is greater than or equal to 1.5cm. For example, the distance between two adjacent electrodes 122 is 1.5cm, 2cm, 2.5cm, 3cm, 3.5cm, 5cm, 7cm, 9cm, etc., to prevent mutual electric creep and thus better ensure the stable operation of the negative ion generator 1.

[0048] Continue to refer to Figures 1 to 3 And in accordance with Figure 1 As shown, the three electrodes 122 of the negative ion generating component 12 on the left, from left to right, are a carbon brush, a needle, and a tungsten filament; the three electrodes 122 of the negative ion generating component 12 on the right, from left to right, are a tungsten filament, a needle, and a carbon brush. The needle can be a tungsten needle or a stainless steel needle. Six circular holes on the casing 112 are respectively positioned corresponding to the two sets of negative ion generating components 12. When assembled, the six circular holes are precisely aligned with the six electrodes 122 of the two sets of negative ion generating components 12. This ensures that at least some air enters and exits through these circular holes when air flows through the negative ion generator 1, thereby better ensuring sufficient contact between the air and the electrodes 122. Specifically, when the negative ion generator 1 is running, under DC high voltage, the three different tips—carbon brush, needle, and tungsten filament—generate high corona discharge, ionizing the air. The negative high voltage releases a large number of electrons (e) at extremely high speed. - Electrons cannot exist in the air for long (the lifespan of an electron is only on the order of nanoseconds) and are immediately captured by oxygen molecules (O2) in the air, thus generating negative air ions. Furthermore, its release capacity shows almost no decrease after prolonged use, producing a large number of negative ions.

[0049] It should be noted that the three electrodes 122, from left to right, can also be a carbon brush, a tungsten filament, and a needle, or a needle, a carbon brush, and a tungsten filament, or a needle, a tungsten filament, and a carbon brush, etc. Of course, all three electrodes 122 can also be the same type of carbon brush, needle, or tungsten filament; for example, all three electrodes 122 can be carbon brushes, etc. Obviously, the electrodes 122 can also be other possible forms such as titanium alloy needles, titanium alloy mesh electrodes 122, photocatalytic coated electrodes 122, and ceramic electrodes 122. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific arrangement of the electrodes 122 according to the specific application scenario, as long as they can ionize air to generate negative ions.

[0050] In summary, in the preferred embodiment of this utility model, by arranging a negative ion generating component 12 and a light-emitting component 13 within the housing 11, and aligning at least a portion of the light-emitting component 13 with the housing 11, the wall-mounted air conditioner can ionize the air to generate negative ions during operation. This improves indoor air quality and benefits the user's health, while also allowing the user to intuitively perceive the negative ion function of the wall-mounted air conditioner, effectively enhancing the user's experience. By placing the light-emitting component 13 between two sets of negative ion generating components 12 arranged along the length of the housing 11, placing a light-transmitting component 15 at a position corresponding to the light-emitting component 13, and placing the light-emitting component 13 near the inner wall of the mounting plate 1111, it is ensured that the light emitted by the light-emitting component 13 can be illuminated through the light-transmitting component 15. This ensures that the user can intuitively perceive the negative ion function of the wall-mounted air conditioner through the light emitted by the light-emitting component 13 during operation of the negative ion generator 1. By including multiple electrodes 122 in the negative ion generating component 12, arranging at least a portion of the multiple electrodes 122 along the length direction of the housing 11, and ensuring that the distance between two adjacent electrodes 122 is greater than or equal to 1.5 cm, a larger area can be covered, more negative ions can be generated, and the stable operation of the negative ion generator 1 can be ensured.

[0051] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0053] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
