[0002] There are more or less bacteria in the air. These bacteria usually attach to dust or droplets and stay suspended in the air with the dust and droplets. Especially in environments with high humidity, high dust, poor ventilation, and insufficient sunlight (such as indoor spaces), the bacteria content in the air is particularly high and their survival time is relatively long. The presence of bacteria can make the air a medium for spreading respiratory diseases, which seriously endangers people's health.

[0035] At present, the sterilization module configured on the air conditioner usually only has a sterilization function, and cannot know the current sterilization effect and the specific sterilization process in real time, resulting in the sterilization module being turned on and off in time, which is prone to incomplete sterilization or over-sterilization. To this end, the sterilization module of the present invention includes a sterilization module and a bacteria detection module.

[0036] Refer to the following Figures 1 to 7 To illustrate the possible implementation methods of the sterilization module of the utility model.

When the wall-mounted air conditioner is running, after the air enters the casing 1, the temperature is adjusted, and it can also be sterilized by the sterilization module, and the bacteria content in the air can be detected in real time by the bacteria detection module 32, and the bacteria content detected by the bacteria detection module 32 is fed back to the wall-mounted air conditioner, and the wall-mounted air conditioner automatically turns on the sterilization module according to the level of the bacteria content, or the bacteria content detected by the bacteria detection module 32 is displayed through the display screen on the wall-mounted air conditioner, or the remote control, or the APP paired with the wall-mounted air conditioner, etc., and the user manually turns on the sterilization module after seeing the specific bacteria content, etc. Through such a setting, the temperature of the indoor space can be adjusted, and the air can be sterilized in a timely and accurate manner, thus avoiding the problem of incomplete sterilization or excessive sterilization.

[0038] like Figures 1 to 4As shown, the sterilization module includes a UVC lamp bead (not shown), which can emit ultraviolet rays, and the ultraviolet rays can sterilize the surface of objects and air within its irradiation range. The mounting bracket 31 is roughly a long rectangular structure, on which a first mounting position 311 and a second mounting position 312 are formed, and the first mounting position 311 and the second mounting position 312 are distributed along the length direction of the mounting bracket 31. The sterilization module is arranged on the first mounting position 311, and the bacteria detection module 32 is arranged on the second mounting position 312. The installed sterilization module and the bacteria detection module 32 are also distributed on the mounting bracket 31 along the length direction of the mounting bracket 31. When the air flows through the sterilization module 3, it can be sterilized in time when the bacteria content in the air is detected, so as to better improve the air quality. When installed, the ultraviolet light emitted by the UVC lamp bead can fill the housing 1, and then sterilize all the air entering the housing 1 and all areas in the housing 1.

[0039] like Figures 1 to 4 As shown, four first buckles 3111 are arranged on the first mounting position 311, and the four first buckles 3111 are arranged opposite to each other in pairs and surround to form a roughly rectangular clamping position. The UVC lamp bead is roughly a rectangular structure and can be clamped in the clamping position, so that the sterilization module is arranged on the mounting bracket 31. The ultraviolet light emitted by the UVC lamp bead when powered on can irradiate most or even all areas in the housing 1, and sterilize the air entering the housing 1, the inner wall of the housing 1, the surface of the heat exchanger 2, etc. Obviously, the UVC lamp bead can also be arranged in the first mounting position 311 by screwing, bonding, etc.

[0040] like Figures 1 to 7 As shown, the bacteria detection module 32 includes a shell 321, and the shell 321 is surrounded by a side portion, a bottom plate and a top plate 3220, wherein the side portion includes a first side wall 3211, a second side wall 3212, a third side wall 3213, a fourth side wall 3214, a fifth side wall 3215 and a sixth side wall 3216 arranged in sequence, the first side wall 3211 and the fifth side wall 3215 are arranged opposite to each other, the second side wall 3212 and the fourth side wall 3214 are connected to each other through the third side wall 3213, the second side wall 3212, the fourth side wall 3214 and the sixth side wall 3216 are parallel to each other, and the first side wall 3211, the third side wall 3213 and the fifth side wall 3215 are parallel to each other. Figure 5In the orientation shown, the upper side of the first side wall 3211 is connected to the left side of the second side wall 3212, and the lower side is connected to the left side of the sixth side wall 3216. The upper side of the fifth side wall 3215 is connected to the right side of the fourth side wall 3214, and the lower side is connected to the right side of the sixth side wall 3216. The distance between the second side wall 3212 and the sixth side wall 3216 is greater than the distance between the fourth side wall 3214 and the sixth side wall 3216. In other words, the side portion of the housing 321 is generally a special-shaped structure surrounded by six side walls, and the outer walls of the second side wall 3212, the fourth side wall 3214 and the sixth side wall 3216 are respectively formed with a card slot 3217, which is generally a long strip structure, and each card slot 3217 extends along the length direction of each side wall (roughly the length direction of the mounting bracket 31). Five limiting structures are arranged on the second installation position 312, of which four are second buckles 3121 and one is an elastic limiting block 3122. The four second buckles 3121 are arranged opposite to each other in pairs, and the elastic limiting block 3122 is located on the right side of the four second buckles 3121. The four second buckles 3121 and the elastic limiting block 3122 are roughly arranged to form a limiting space adapted to the side of the housing 321. When installed, two of the four second buckles 3121 are matched and connected with the slots 3217 on the sixth side wall 3216, and the other two are matched and connected with the slots 3217 on the second side wall 3212 and the fourth side wall 3214, respectively, and the elastic limiting block 3122 is in contact with the outer wall of the fifth side wall 3215, so that the bacteria detection module 32 is fixed in the limiting space.

[0041] It should be noted that the limiting structure may also include only the second buckle 3121, or include four second buckles 3121 and two elastic limiting blocks 3122, or include other numbers of second buckles 3121 and elastic limiting blocks 3122. Obviously, the limiting structure may also be composed of other structures such as hooks or claws, and accordingly, the outer wall of the shell 321 is provided with matching structures such as holes or blocks. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting form of the limiting structure according to the specific application scenario, as long as the bacteria detection module 32 can be set in the second installation position 312. Of course, the bacteria detection module 32 can also be set in the second installation position 312 by screwing, bonding, etc.

[0042] It should be noted that a plurality of first mounting positions 311 may be formed on the mounting bracket 31, each of which is provided with a sterilization module, and the plurality of first mounting positions 311 and the second mounting positions 312 are distributed along the length direction of the mounting bracket 31. Of course, a part of the plurality of first mounting positions 311 and the second mounting positions 312 may be distributed along the length direction of the mounting bracket 31, and another part may be distributed along the width direction of the mounting bracket 31.

[0043] It should be noted that the sterilization module can also be a UVC lamp, UVA lamp beads or UVA lamps and other devices that can emit ultraviolet rays. Obviously, the sterilization module can also be a positive / negative ion sterilization module, an ozone sterilization module, a silver ion sterilization module, etc. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting form of the sterilization module according to the specific application scenario, as long as the air can be sterilized.

[0044] It should be noted that, in this embodiment, the length direction of the mounting bracket 31 is approximately Figure 1 The length direction of the casing 1 is shown.

[0045] like Figure 1 , Figure 2 , Figures 5 to 7As shown, the bacteria detection module 32 also includes an excitation light source 324, a fluorescence detection device 325, a fan 326 and a light processing unit 327 arranged in the housing 321, wherein the excitation light source 324 is configured to emit excitation light after being powered on, and the excitation light can excite the bacteria carried in the air to emit fluorescence. The excitation light source 324 can be a laser emitter or a laser, or an ultraviolet lamp or LED lamp that can emit UVA ultraviolet rays, or a device that can emit excitation light containing a band of 340nm to 405nm, etc. The fluorescence detection device 325 is configured to detect the fluorescence emitted by the bacteria carried in the air after irradiating the air with the excitation light after being powered on, and output the detection result. The light processing unit 327 can adjust the excitation light so as to better excite the bacteria in the air, and can adjust the fluorescence so that the fluorescence detection device 325 can better capture and detect the fluorescence. In this way, the bacterial content in the air can be quickly detected by the irradiation of the excitation light and the detection of the fluorescence detection device 325, without sampling and culturing, and the detection process is simple and fast. The fan 326 can introduce the air to be detected into the housing 321 and send the detected air out of the housing 321. For example, the fan 326 can be an axial flow fan 326, a centrifugal fan 326, etc. The fan 326 can make the air pass through the housing 321 at a relatively stable flow rate, thereby ensuring the detection accuracy of the bacteria detection device. The housing 321 is provided with a first partition 322 and a second partition 323. One side of the first partition 322 is connected to the second side wall 3212 and the other side is connected to the sixth side wall 3216. One side of the second partition 323 is connected to the first side wall 3211 and the other side is connected to the first partition 322. The first partition 322 divides the housing 321 into three chambers. The first chamber 10 is roughly an L-shaped structure, and the second chamber 20 and the third chamber 30 are roughly rectangular structures. The excitation light source 324 is embedded in the fifth side wall 3215, the fluorescence detection device 325 is embedded in the second side wall 3212, and the light processing unit 327 is arranged in the first chamber 10. A support 328 is arranged in the third chamber 30, and a fan 326 is seated on the support 328. A through hole 3221 is arranged on the first partition 322, through which the first chamber 10 and the second chamber 20 can be connected. The through hole 3221 is roughly a rectangular hole. When installed, the excitation light emitted by the excitation light source 324 is along the length direction of the sixth side wall 3216 (roughly Figure 2 The second partition plate 323 is provided with a plurality of vents 3231, through which the second chamber 20 and the third chamber 30 can be connected.

[0046] The light processing unit 327 includes a collimating lens group 3271, a uniform light filter group 3272, a dichroic mirror 3273 and a collecting lens group 3274, wherein the excitation light source 324, the collimating lens group 3271, the uniform light filter group 3272 and the dichroic mirror 3273 are arranged along the length direction of the sixth side wall 3216, and the dichroic mirror 3273, the collecting lens group 3274 and the fluorescence detection device 325 are arranged along the length direction of the first partition 322 (approximately Figure 2 The fourth side wall 3214 and the sixth side wall 3216 are provided with slots opposite to each other, and the two ends of the two collimating lenses are respectively inserted into the corresponding slots and arranged on the downstream side of the excitation light source 324, so as to adjust the excitation light emitted by the excitation light source 324 into light irradiated in the same direction. In this embodiment, the excitation light adjusted by the collimating lens group 3271 is irradiated along the length direction of the sixth side wall 3216. The light homogenizing filter group 3272 includes a light homogenizing plate and a filter. Slots are arranged opposite to each other on the fourth side wall 3214 and the sixth side wall 3216. Both ends of the light homogenizing plate and the filter are respectively inserted into the corresponding slots and arranged on the downstream side of the collimating lens group 3271, so as to evenly distribute the energy of each wavelength in the light passing therethrough and filter out part of the light that cannot excite the bacteria to emit fluorescence. In this way, the excitation light irradiated to the air will be more uniform and pure, thereby being able to better excite the bacteria in the air. The dichroic mirror 3273 is arranged at the downstream side of the light homogenizing filter group 3272, at the corner of the first chamber 10 and close to the second chamber, and the angle between the dichroic mirror 3273 and the sixth side wall 3216 is approximately 45°. The dichroic mirror 3273 is used to filter the stray light in the excitation light so as to allow the light that can excite the bacteria to emit fluorescence to pass through, and to reflect the fluorescence emitted by the bacteria to the fluorescence detection device 325, for example, to allow the light with a wavelength between 340nm and 405nm to pass through, and to reflect the light with a wavelength between 405nm and 600nm, etc. The collecting lens group 3274 includes two lenses, and slots are arranged on the third side wall 3213 and the first partition plate 322. The two ends of the two lenses are respectively inserted into the corresponding slots, arranged on the downstream side of the dichroic mirror 3273 and the upstream side of the fluorescence detection device 325, and are used to gather the fluorescence reflected by the dichroic mirror 3273 and focus it on the fluorescence detection device 325, so that the fluorescence can be detected by the fluorescence detection device 325. The fluorescence detection device 325 can analyze fluorescence. Since different bacteria absorb laser energy and form different fluorescence spectra, the bacterial content in the air can be determined by detecting the strength of the fluorescence signal and analyzing the fluorescence characteristics.

[0047] The housing 321 is provided with an inlet 3218 and an outlet 3219 . The inlet 3218 is communicated with the second chamber 20 . An air inlet pipe 32181 is provided at the inlet 3218 . The outlet 3219 is communicated with the third chamber 30 . An air outlet pipe 32191 is provided at the outlet 3219 . When the bacteria detection module 32 is running, under the action of the fan 326, the air outside the shell 321 can enter the second chamber 20 through the air inlet pipe 32181 and the inlet 3218, and the excitation light emitted by the excitation light source 324 passes through the collimating lens group 3271, the uniform light filter group 3272, the dichroic mirror 3273 and the through hole 3221 to irradiate the second chamber 20. This part of the air is excited by the irradiation of the light, and the bacteria carried therein emit fluorescence. The fluorescence then passes through the through hole 3221 and returns to the first chamber 10, and is reflected by the dichroic mirror 3273 to the collecting lens group 3274. The fluorescence is collected by the collecting lens group 3274 to the fluorescence detection device 325, and the bacteria content in the air can be detected by the fluorescence detection device 325. After being irradiated by the excitation light, the air in the second chamber 20 enters the third chamber 30 through the vent hole 3231 on the second partition 323 under the action of the fan 326, and then is discharged from the housing 321 through the outlet 3219 and the air outlet pipe 32191. In other words, the second chamber 20 serves as a detection chamber. Under the action of the fan 326, the air is sucked into the detection chamber and irradiated by the excitation light, and then the bacteria content in the air can be determined by the fluorescence detection device 325. The air in the detection chamber is then sent out of the housing 321 by the fan 326, so that the bacteria content in the air flowing through the bacteria detection device can be detected in real time, and the bacteria content in the air of the indoor space can be monitored in real time.

[0048] It should be noted that the air inlet 32181 and the air outlet 32191 may not be provided on the housing 321, and the air outside the housing 321 directly enters the housing 321 through the inlet 3218 and is discharged from the housing 321 through the outlet 3219. Obviously, the bacteria detection module 32 may not include the fan 326. When the bacteria detection module 32 is set in the air duct, a part of the air flowing in the air duct will naturally enter the housing 321 through the inlet 3218 and then flow out of the housing 321 through the outlet 3219. Of course, the bacteria detection module 32 may not detect the bacterial content based on the principle that bacteria are excited to emit fluorescence. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting method of the bacteria detection module 32 according to the specific application scenario, as long as the bacteria detection module 32 can accurately detect the bacterial content in the air.

[0049] like Figures 2 to 4As shown, the sterilization module 3 also includes a power supply module (not shown), for example, the power supply module is a circuit board, which is roughly rectangular. A third mounting position 313 is also provided on the mounting bracket 31, and the power supply module can be set on the mounting bracket 31 by means of snap connection or screw connection. The circuit board is connected to the power supply of the wall-mounted air conditioner, and the power supply of the sterilization module and the bacteria detection module 32 can be ensured through the power supply module, thereby ensuring the stable operation of the sterilization module 3. Obviously, the power supply module can also only supply power to one of the sterilization module and the bacteria detection module 32, and the other one through other power supply modules or share a power supply module with the wall-mounted air conditioner.

[0050] It should be noted that the power supply module can also be a storage battery, a dry cell or a rechargeable battery, etc., through which the sterilization module and the bacteria detection module 32 are powered separately. Of course, the mounting bracket 31 may not be provided with a power supply module separately, but the circuit board for powering the sterilization module 3 may be integrated into the circuit board of the wall-mounted air conditioner. Without departing from the basic principles of the present application, those skilled in the art can flexibly choose whether to set the power supply module and the specific setting method of the power supply module according to the specific application scenario, as long as the power supply of the sterilization module and the bacteria detection module 32 can be ensured.

[0051] Refer to the following Figures 1 to 4 To illustrate the possible implementation of the wall-mounted air conditioner of the utility model equipped with the above-mentioned sterilization module 3.

[0052] like Figures 1 to 4 As shown, a heat exchanger 2 and an indoor fan (not shown) are arranged in a housing 1 of the wall-mounted air conditioner. The indoor fan may be a cross-flow fan 326. The housing 1 has an air inlet 11 and an air outlet 12. An air duct is formed between the air inlet 11 and the air outlet 12. The heat exchanger 2 is arranged in the air duct. Figure 2 The left end of the mounting bracket 31 shown in FIG. 1 is provided with two screw holes 314, the second end (approximately Figure 2The third buckle 315 is provided at the right end of the mounting bracket 31 shown in the figure. The front side of the inner wall of the housing 1 is correspondingly provided with a mounting hole and a clamping hole. During installation, the third buckle 315 is matched with the clamping hole, and then the fastener (such as a bolt, a screw, etc.) is passed through the screw hole 314 and connected with the mounting hole, so that the sterilization module 3 is fixed on the inner wall of the housing 1 by screwing and clamping. When installed, the sterilization module 3 is located between the heat exchanger 2 and the housing 1 and close to the air inlet 11, so that the sterilization module 3 is set in the air duct, and the sterilization module and the bacteria detection module 32 are distributed along the length direction of the housing 1. When the wall-mounted air conditioner is running, the indoor fan is turned on and operated. Under the action of the indoor fan, the air in the indoor space enters the housing 1 through the air inlet 11, exchanges heat with the heat exchanger 2, reaches the air outlet 12 through the air duct, and then returns to the indoor space, thereby achieving the purpose of adjusting the temperature of the indoor space. At the same time, part of the air entering the housing 321 enters the second chamber 20 through the air inlet pipe on the bacteria detection module 32 in the sterilization module 3. After being irradiated by the excitation light, the fluorescence emitted by the bacteria in the air is captured by the fluorescence detection device 325, and the bacterial content in the air is finally determined. This part of the air can be irradiated by the ultraviolet rays emitted by the UVC lamp beads on the sterilization module to sterilize it. Through such a setting, the temperature of the indoor space can be adjusted, and the air can be sterilized in a timely and accurate manner to avoid the problem of incomplete sterilization or excessive sterilization, thereby better improving the air quality of the indoor space and enhancing the user experience.

[0053] It should be noted that screw holes 314 may be provided at both ends of the mounting bracket 31, or third buckles 315 may be provided at both ends, that is, the mounting bracket 31 may be provided in the housing 1 only by screwing or only by snapping. Obviously, the mounting bracket 31 may also be provided in the housing 1 by other possible means such as magnetic adsorption and bonding. Without departing from the basic principles of the present application, those skilled in the art may flexibly select the specific setting method of the sterilization module 3 according to the specific application scenario, as long as the sterilization module 3 can be provided in the air duct.

[0054] It should be noted that the sterilization module 3 can also be set on the heat exchanger 2 by screwing, clamping, bonding, etc. Obviously, the sterilization module 3 can also be set between the heat exchanger 2 and the indoor fan by screwing, clamping, bonding, etc., or set on the side of the air inlet grille at the air inlet 11 facing the inside of the casing 1 by screwing, clamping, bonding, etc. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting position of the sterilization module 3 according to the specific application scenario, as long as the sterilization module 3 can be set in the air duct.

[0055] In a possible implementation, a display screen is provided on the wall-mounted air conditioner, and the display screen is in communication connection with the bacteria detection module 32. After the bacteria detection module 32 detects the bacteria content in the air, the bacteria content is transmitted to the display screen, and displayed on the display screen, so that the user can know the current air quality in real time. Obviously, it is also possible that the wall-mounted air conditioner is not provided with a display screen, or the display screen does not display the detection result of the bacteria detection module 32, but the detection result of the bacteria detection module 32 is displayed through a remote control matched with the wall-mounted air conditioner, or an APP matched with it.

[0056] In summary, in the preferred technical solution of the utility model, the bacteria content in the air is detected in real time by the bacteria detection module 32 of the sterilization module 3, the air is sterilized by the sterilization module in the sterilization module 3, and the sterilization module 3 is set on the wall-mounted air conditioner through the mounting bracket 31, so that the temperature of the indoor space can be adjusted and the air can be sterilized in time and accurately, thereby avoiding the problem of incomplete sterilization or excessive sterilization. By making the first mounting position 311 and the second mounting position 312 distributed along the length direction of the mounting bracket 31, the sterilization module is clamped in the first mounting position 311, and the bacteria detection module 32 is clamped in the second mounting position 312, the air can be sterilized in time when the bacteria content in the air is detected, so as to better improve the air quality. By making the bacteria detection module 32 include an excitation light source 324 and a fluorescence detection device 325, and setting an air inlet pipe 32181 and an air outlet pipe 32191 on the housing 321, the bacteria content in the air can be directly detected by irradiating the excitation light and the fluorescence detection device 325, and the detection process is simple and fast. The mounting bracket 31 is set on the inner side of the housing 1 by screwing and clamping, and the sterilization module 3 is set between the heat exchanger 2 and the housing 1, near the air inlet 11, so that the sterilization module 3 is set in the air duct. When the wall-mounted air conditioner is running, it can not only adjust the temperature of the indoor space, but also sterilize the air in a timely and accurate manner.

[0057] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.
