Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0037] Some current air treatment devices, such as multi-function air purifiers and humidifying fans, often integrate functions such as humidity control. Multi-function air purifiers, in particular, combine dehumidification and purification. They not only dehumidify the air but also purify it, improving user comfort.

[0038] Current multi-functional air purifiers typically consist of an air purifier, dehumidifier, and wet curtain humidifier. The filter removes dust and particulate matter from the air, while the compressor and two devices (the evaporator and condenser) condense moisture from the air onto the fins of the two devices, achieving the dehumidification effect.

[0039] Multi-function air purifiers or humidifying fans use wet curtains to increase the humidity of the air flowing through them, thereby achieving an air humidification effect. However, the fins of multi-function air purifiers or wet curtains need to be in a humid environment for a long time, which can easily breed bacteria. Even after drying, the bacteria cannot be inactivated.

[0040] Based on the above technical problems, the present utility model is proposed. The utility model may include a deflector 1, a lamp holder 2, at least one first ultraviolet light bar 3, and a lamp cover 4.

The lamp cover 4 is located on the first ultraviolet light bar 3 and cooperates with the lamp holder 2 to form a seal around the first ultraviolet light bar 3. When the first ultraviolet light bar 3 is in operation, it illuminates the components located below the lamp holder 2, thereby sterilizing the components of the air handling equipment in a humid environment, avoiding the generation of odor, and improving the user's health and well-being.

[0041] Reference Figure 1-6 The present invention provides an air treatment device, which may include a deflector 1, a lamp holder 2, at least one first ultraviolet light bar 3, and a lamp cover 4.

[0043] The lamp cover 4 is located on the end face of the first UV light strip 3 facing away from the lamp holder 2.

[0047] In an embodiment of the present invention, the air treatment device may include a guide plate 1, a lamp holder 2, a first ultraviolet light bar 3, and a lamp cover 4. The guide plate 1 is used to guide the airflow through the air treatment device, and the lamp holder 2 is fixed to the guide plate 1 to provide an assembly position for the first ultraviolet light bar 3. At least one first ultraviolet light bar 3 is mounted on the lamp holder 2. The first ultraviolet light bar 3 can emit ultraviolet light when powered. The ultraviolet light damages and changes the DNA (deoxyribonucleic acid) structure of microorganisms, thereby achieving the purpose of sterilization.

[0048] The lamp cover 4 is located on the end face of the first UV light strip 3 facing away from the lamp holder 2. The lamp cover 4 cooperates with the lamp holder 2 to enclose the first UV light strip 3. In other words, the lamp cover 4 and the lamp holder 2 both limit the position of the first UV light strip 3 and protect the first UV light strip 3 and the corresponding electrical circuits.

[0049] In some optional embodiments, the lamp holder 2 may include a first mounting portion 21 and a second mounting portion 22, and the first mounting portion 21 and the second mounting portion 22 are fixedly connected. In some preferred embodiments, the first mounting portion 21 and the second mounting portion 22 may be arranged perpendicular to each other. For example, the second mounting portion 22 may form surface contact with the guide plate 1 in the vertical direction. The first ultraviolet light strip 3 may be mounted on the first mounting portion 21, so that the light source direction of the first ultraviolet light strip 3 can be set vertically downward by the setting of the first mounting portion 21. In this way, the device located below the first mounting portion 21 can be irradiated and sterilized.

[0050] In one example, the first mounting portion 21 and the second mounting portion 22 can be an integrated structure. When the first UV light strip 3 is in operation, it illuminates components located below the lamp holder 2. The UV light emitted can sterilize the surfaces of components located below the lamp holder 2. This sterilizes components of air handling equipment in humid environments, prevents odor and bacterial growth, and significantly improves the user's health and well-being.

[0051] In an optional embodiment of the utility model, the air treatment device may include a deflector 1, a lamp holder 2, at least one first ultraviolet light strip 3, and a lamp cover 4. The lamp holder 2 is fixedly connected to the deflector 1, and at least one first ultraviolet light strip 3 is mounted on the lamp holder 2. The lamp cover 4 is located on the first ultraviolet light strip 3 and cooperates with the lamp holder 2 to form a seal around the first ultraviolet light strip 3.

[0052] The lamp holder 2 may include a first mounting portion 21 and a second mounting portion 22 connected to the first mounting portion 21. The first UV light bar 3 is mounted on the first mounting portion 21, and the second mounting portion 22 is fixedly connected to the deflector 1. When the first UV light bar 3 is in operation, it illuminates the device located below the lamp holder 2. Furthermore, a mounting groove 2101 is defined on the first mounting portion 21. The first UV light bar 3 is embedded in the mounting groove 2101, so that the mounting groove 2101 forms a limit for the first UV light bar 3. The first UV light bar 3 may also pass through the mounting groove 2101 and extend outside the first mounting portion 21.

[0053] In an embodiment of the present invention, the air treatment device may include a guide plate 1, a lamp holder 2, a first ultraviolet light bar 3, and a lamp cover 4. The guide plate 1 is used to guide the airflow through the air treatment device, and the lamp holder 2 is fixed to the guide plate 1 to provide an assembly position for the first ultraviolet light bar 3. At least one first ultraviolet light bar 3 is mounted on the lamp holder 2. The first ultraviolet light bar 3 can emit ultraviolet light when powered. The ultraviolet light damages and changes the DNA (deoxyribonucleic acid) structure of microorganisms, thereby achieving the purpose of sterilization.

[0054] The lamp cover 4 is located on the end face of the first UV light strip 3 away from the lamp holder 2. The lamp cover 4 cooperates with the lamp holder 2 to enclose the first UV light strip 3. Furthermore, the first mounting portion 21 defines a mounting groove 2101, into which the first UV light strip 3 is embedded, thereby limiting the position of the first UV light strip 3.

[0055] That is, during the assembly process of the first ultraviolet light bar 3, the first ultraviolet light bar 3 can be first embedded in the mounting groove 2101, thereby forming a horizontal limit for the first ultraviolet light bar 3 through the mounting groove 2101. After the first ultraviolet light bar 3 is installed, the lamp cover 4 is covered on the first ultraviolet light bar 3 and fixedly connected to the first mounting portion 21, thereby forming a vertical limit for the first ultraviolet light bar 3. On the one hand, the lamp cover 4 and the lamp holder 2 can limit the first ultraviolet light bar 3. On the other hand, the lamp cover 4 and the lamp holder 2 can protect the first ultraviolet light bar 3 and the corresponding electrical circuits.

[0056] In some optional embodiments, the lamp holder 2 may include a first mounting portion 21 and a second mounting portion 22, wherein the first mounting portion 21 and the second mounting portion 22 are fixedly connected. In some preferred embodiments, the first mounting portion 21 and the second mounting portion 22 may be arranged perpendicular to each other. In other words, the angle formed between the first mounting portion 21 and the second mounting portion 22 is 90°.

[0057] For example, the second mounting portion 22 can form a vertical surface contact with the deflector 1. The first UV light strip 3 can be mounted on the first mounting portion 21. This allows the light source of the first UV light strip 3 to be directed vertically downward. This allows components located below the first mounting portion 21 to be illuminated and sterilized.

[0058] In one example, the first mounting portion 21 and the second mounting portion 22 can be an integrated structure. When the first UV light strip 3 is in operation, it illuminates components located below the lamp holder 2. The UV light emitted can sterilize the surfaces of components located below the lamp holder 2. This sterilizes components of air handling equipment in humid environments, prevents odor and bacterial growth, and significantly improves the user's health and well-being.

[0059] In an optional embodiment of the utility model, the second mounting portion 22 is fixedly connected to the guide plate 1 by snapping.

[0060] In an embodiment of the present invention, a buckle may be provided on the second mounting portion 22, and correspondingly, a buckle groove may be preset on the guide plate 1, so that the buckle can cooperate with the buckle groove to form a snap connection and fixation between the second mounting portion 22 and the guide plate 1.

The fastener 5 passes through the assembly hole and the threaded hole, and the fastener 5 is threadedly connected to the guide plate 1 to form a fixation between the second mounting portion 22 and the guide plate 1.

[0063] In some optional embodiments of the utility model, when the second mounting portion 22 and the guide plate 1 are fixed by a snap connection, fasteners 5 can be used to fix the second mounting portion 22 and the guide plate 1, thereby further improving the connection stability between the second mounting portion 22 and the guide plate 1.

[0065] In the embodiment of the present invention, there are at least three first UV light strips 3, which are spaced apart on the lamp frame 2, thereby solving the problem of limited UV irradiation coverage and enabling devices located below the first UV light strips 3 to be fully sterilized.

[0066] Those skilled in the art can select the number of the first ultraviolet light strips 3 according to the specifications of the devices located below the first ultraviolet light strips 3. For example, the number of the first ultraviolet light strips 3 can be 3, 4 or 5, etc., which is not limited here.

[0067] An optional embodiment of the utility model, referring to Figure 5 As shown, when the number of the first ultraviolet light strips 3 is set to be more than two, the more than two first ultraviolet light strips 3 are connected.

[0069] An optional embodiment of the utility model, referring to Figure 1 、 Figure 3 、 Figure 5 as well as Figure 6 As shown, the air treatment device may include a deflector 1, a lamp holder 2, at least one first ultraviolet light bar 3, and a lamp cover 4. The lamp holder 2 is fixedly connected to the deflector 1, and at least one first ultraviolet light bar 3 is mounted on the lamp holder 2.

The lamp holder 2 may include a first mounting portion 21 and a second mounting portion 22 connected to the first mounting portion 21. The first ultraviolet light bar 3 is mounted on the first mounting portion 21, and the second mounting portion 22 is fixedly connected to the deflector 1. When the first ultraviolet light bar 3 is in operation, it illuminates the device located below the lamp holder 2. Furthermore, the first mounting portion 21 defines a mounting groove 2101, and the first ultraviolet light bar 3 is embedded in the mounting groove 2101 to limit the position of the first ultraviolet light bar 3. In which, a light-transmitting hole 101 is opened on the guide plate 1, and the air treatment device also includes a second ultraviolet light strip 6, which is fixed on the lamp holder 2 and arranged toward the light-transmitting hole 101, wherein the light-transmitting hole 101 is connected to the air outlet so that the second ultraviolet light strip 6 can purify the air at the air outlet when it is working.

[0070] In an embodiment of the present invention, the air treatment device may include a guide plate 1, a lamp holder 2, a first ultraviolet light bar 3, and a lamp cover 4. The guide plate 1 is used to guide the airflow through the air treatment device, and the lamp holder 2 is fixed to the guide plate 1 to provide an assembly position for the first ultraviolet light bar 3. At least one first ultraviolet light bar 3 is mounted on the lamp holder 2. The first ultraviolet light bar 3 can emit ultraviolet light when powered. The ultraviolet light damages and changes the DNA (deoxyribonucleic acid) structure of microorganisms, thereby achieving the purpose of sterilization.

[0071] The lamp cover 4 is located on the end face of the first UV light strip 3 away from the lamp holder 2. The lamp cover 4 cooperates with the lamp holder 2 to enclose the first UV light strip 3. Furthermore, the first mounting portion 21 defines a mounting groove 2101, into which the first UV light strip 3 is embedded, thereby limiting the position of the first UV light strip 3.

[0072] That is, during the assembly process of the first ultraviolet light bar 3, the first ultraviolet light bar 3 can be first embedded in the mounting groove 2101, thereby forming a horizontal limit for the first ultraviolet light bar 3 through the mounting groove 2101. After the first ultraviolet light bar 3 is installed, the lamp cover 4 is covered on the first ultraviolet light bar 3 and fixedly connected to the first mounting portion 21, thereby forming a vertical limit for the first ultraviolet light bar 3. On the one hand, the lamp cover 4 and the lamp holder 2 can limit the first ultraviolet light bar 3. On the other hand, the lamp cover 4 and the lamp holder 2 can protect the first ultraviolet light bar 3 and the corresponding electrical circuits.

[0073] In some optional embodiments, the lamp holder 2 may include a first mounting portion 21 and a second mounting portion 22, and the first mounting portion 21 and the second mounting portion 22 are fixedly connected. In some preferred embodiments, the first mounting portion 21 and the second mounting portion 22 may be arranged perpendicular to each other. That is, the angle formed between the first mounting portion 21 and the second mounting portion 22 is 90°. For example, the second mounting portion 22 may form a surface contact with the guide plate 1 in the vertical direction. The first ultraviolet light strip 3 may be mounted on the first mounting portion 21, so that the light source direction of the first ultraviolet light strip 3 may be set vertically downward by the setting of the first mounting portion 21. In this way, the device located below the first mounting portion 21 may be irradiated and sterilized.

[0074] In one example, the first mounting portion 21 and the second mounting portion 22 can be an integrated structure. When the first UV light strip 3 is in operation, it illuminates components located below the lamp holder 2. The UV light emitted can sterilize the surfaces of components located below the lamp holder 2. This sterilizes components of air handling equipment in humid environments, prevents odor and bacterial growth, and significantly improves the user's health and well-being.

[0075] The deflector 1 is provided with a light-transmitting hole 101. The air treatment device further includes a second ultraviolet light bar 6, which is fixed to the lamp holder 2 and disposed toward the light-transmitting hole 101. The second ultraviolet light bar 6 is fixed to the second mounting portion 22. That is, the second ultraviolet light bar 6 and the first ultraviolet light bar 3 are disposed perpendicular to each other. The ultraviolet light from the first ultraviolet light bar 3 irradiates downward, while the ultraviolet light from the second ultraviolet light bar 6 irradiates toward one side of the deflector 1. The light-transmitting hole 101 is connected to the air outlet, so that when the second ultraviolet light bar 6 is in operation, it irradiates the air at the air outlet with ultraviolet light, thereby sterilizing the air flowing through the air outlet and achieving air purification.

[0076] In some embodiments, the second UV light strip 6 is preferably installed on the guide plate 1 at a position that does not block the airflow direction on the guide plate 1, thereby avoiding a reduction in air volume or noise.

[0077] In summary, the embodiment of the present utility model discloses an air treatment device, which may include a guide plate 1, a lamp holder 2, at least one first ultraviolet light bar 3, and a lamp cover 4. The lamp holder 2 is fixedly connected to the guide plate 1, and at least one first ultraviolet light bar 3 is mounted on the lamp holder 2. The lamp cover 4 is located on the first ultraviolet light bar 3 and cooperates with the lamp holder 2 to form a seal around the first ultraviolet light bar 3. When the first ultraviolet light bar 3 is in operation, it illuminates the components located below the lamp holder 2, thereby sterilizing the components of the air treatment equipment in a humid environment, avoiding the generation of odor, and improving the user's health factor.

[0078] Reference Figure 7 and Figure 8 As shown, the present invention also discloses an air purifier, comprising an evaporator fin 7, a condenser fin 8, and an air treatment device as described in any one of the above-mentioned utility model embodiments. The evaporator fin 7 and the condenser fin 8 are located below the lamp holder 2, so that when the first ultraviolet light strip 3 is in operation, the evaporator fin 7 and the condenser fin 8 are sterilized.

[0079] In an embodiment of the present invention, the air purifier can be an air purifier with a dehumidification device formed by an evaporator and a condenser. It can also be called a multifunctional air purifier, a freshener, etc. Therefore, the lamp holder 2 can be installed on the guide plate 1 so that the evaporator fins 7 and the condenser fins 8 are located below the lamp holder 2. When the first ultraviolet light bar 3 is working, the evaporator fins 7 and the condenser fins 8 are irradiated and sterilized. This can avoid the problems of the evaporator fins 7 and the condenser fins 8 being moldy, odor-generating, and aging-accelerated due to being in a humid environment for a long time. For example, the wavelength of the ultraviolet light emitted by the first ultraviolet light bar 3 is 200 to 400 nm.

[0080] The arrangement of the plurality of first UV light strips 3 allows ultraviolet rays to reach both end surfaces of the evaporator fins 7 and the condenser fins 8, even when the gap between the evaporator fins 7 and the condenser fins 8 is small, thereby fully sterilizing the evaporator fins 7 and the condenser fins 8. The spacing between two adjacent first UV light strips 3 can be determined based on the end surface positions of the evaporator fins 7 and the condenser fins 8.

[0081] During the operation of the air purifier, the air passage in the air purifier can be closed by setting an air guide plate, thereby ensuring that the ozone generated by the first ultraviolet light strip 3 stays in the air passage for full purification and does not flow out of the air purifier.

[0082] In summary, the embodiment of the present utility model discloses an air purifier, which may include a deflector 1, a lamp holder 2, at least one first ultraviolet light strip 3, and a lamp cover 4. The lamp holder 2 is fixedly connected to the deflector 1, and at least one first ultraviolet light strip 3 is mounted on the lamp holder 2. The lamp cover 4 is located on the first ultraviolet light strip 3 and cooperates with the lamp holder 2 to form a seal around the first ultraviolet light strip 3.
