[0046] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0047] Figure 1 This is an exploded view of an embodiment of a sterilization volute of the present invention;

[0048] Figure 2 It is a structural diagram provided by an embodiment of the sterilization volute of the present invention.

[0049] like Figure 1 and Figure 2 As shown, the sterilization volute of this embodiment includes a sterilization device 10 and a volute 11 for mounting a fan body.

[0050] The volute 11 includes a shell body 111 and an end cover 112, and the shell body 111 and the end cover 112 are detachable. An installation groove 113 is provided on the inner side of the shell body 111. When the shell body 111 and the end cover 112 are fixed, the end cover 112 limits the sterilization device 10 in the installation groove. By adopting the technical solution of this embodiment, when installing the sterilization device 10, there is no need for auxiliary installation of mounting parts such as clamps and lamp holders, which simplifies the installation process. When installing the fan body, the shell body 111 can be installed on the motor of the fan body first, and then the fan blades of the fan body can be fixed. The fan blades can be fixed with nuts, and finally the end cover 112 is installed. It is simpler than the traditional installation method of upper and lower volute buckles, further simplifies the installation process, and saves installation time.

[0051] In some optional embodiments, the mounting groove 113 includes a mounting hole A. When installing the sterilization device 10, the sterilization device 10 is placed in the mounting groove 113 through the mounting hole A of the mounting groove 113. In order to further fix the sterilization device 10 in the mounting groove 113, a limiting device 114 is provided on the end cover 112, such as Figure 1 and Figure 2 As shown, when the shell body 111 and the end cover 112 are fixed, the limiting device 114 covers the mounting hole A of the mounting groove 113 to fix the sterilization device 10 in the mounting groove 113 .

[0052] In some optional embodiments, the fan body includes a motor and a fan blade. When installing the fan body, the shell 111 can be installed on the motor first, and then the fan blade is set on the shaft of the motor, and finally the end cover 112 is installed, and the sterilization device 10 can be installed before installing the end cover 112. Optionally, the sterilization device 10 can be installed after the fan blade is installed to avoid the sterilization device 10 falling due to the lack of the limit device 114 on the end cover. The sterilization volute provided in this embodiment is simpler than the traditional installation method of the upper and lower volute buckles, further simplifies the installation process, and saves installation time.

[0053] In some optional embodiments, an end cap 112 may be provided, one side of the mounting slot 113 is a mounting hole A, and the other side of the mounting slot 113 is a blind hole to prevent the sterilization device 10 from falling from the other side of the mounting slot 113. The limiting device 114 on the end cap 112 covers the mounting hole A to fix the sterilization device 10 in the mounting slot 113.

[0054] In some optional embodiments, two end covers 112 may be provided, both sides of the mounting groove 113 are mounting sides, and the limiting devices 114 on the two end covers 112 respectively cover the two mounting holes A to fix the sterilization device 10 in the mounting groove 113 .

[0055] Figure 3 It is a structural diagram provided by another embodiment of the sterilization volute of the present invention.

[0056] like Figure 3 As shown, in some optional embodiments, the limiting device 114 includes a limiting flange S, and when the shell body 111 and the end cover 112 are fixed, the limiting flange S extends into the mounting hole A.

[0057] Specifically, after the sterilization device 10 is inserted into the installation groove 113 , the end cover 112 is fixed, and the limiting flange S extends into the installation hole A to prevent the sterilization device 10 from moving back and forth, and at the same time, the end cover 112 can also be positioned.

[0058] In some optional embodiments, the sterilization device 10 includes an ultraviolet sterilization lamp.

[0059] Ultraviolet sterilization lamps can use UVC purple lamps. UVC purple lamps can kill viruses in the covered air environment and will not produce substances harmful to the human body. It is an efficient and clean sterilization method today.

[0060] In some optional embodiments, the number of mounting slots 113 is at least two, and each mounting slot 113 corresponds to a group of ultraviolet sterilization lamps, that is, the number of ultraviolet sterilization lamps is at least two groups, so that the ultraviolet light emitted by the ultraviolet sterilization lamp covers the fan body, and the light scattering can cover the internal structure of the sterilization volute, and fully meet the optimal distance of UVC of 10cm, thereby maximizing the sterilization effect, purifying the air passing through the sterilization volute, and achieving the purpose of sterilization.

[0061] Among them, a group of ultraviolet germicidal lamps may include one or more ultraviolet germicidal lamps, which is not limited in this embodiment.

[0062] The shell body 111 is provided with an air outlet P, and the number of the mounting grooves 113 includes three. Correspondingly, the number of the ultraviolet germicidal lamps is three groups. Figure 4 FIG. 1 is a distribution diagram of ultraviolet germicidal lamps provided by an embodiment of the sterilization volute of the present invention. In some optional embodiments, the three mounting slots 113 can be arranged according to Figure 4 In some other embodiments, the three mounting grooves 113 can also be evenly arranged on the inner wall of the shell 111 and avoid the air outlet P. The ultraviolet germicidal lamps are evenly distributed to ensure that the air passing through the fan body is completely covered by the ultraviolet light, thereby improving the sterilization efficiency.

[0063] It should be noted that whether to install the sterilization device 10 can be determined based on actual conditions, and this embodiment does not limit this.

[0064] In some optional embodiments, the shell body 111 and the end cover 112 are detachably fixed by a buckle 13, such as Figure 1 , Figure 2 and Figure 3 shown.

[0065] Figure 5 It is a circuit schematic diagram provided by one embodiment of the sterilization volute of the present invention.

[0066] like Figure 5 As shown, in some optional embodiments, an air detection device 13 and a controller 14 are also included, and the controller 14 is connected to the air detection device 13 and the sterilization device 10 respectively.

[0067] The air detection device 13 includes: a formaldehyde sensor 131, a PM2.5 detection sensor 132, and a temperature and humidity detection sensor 133. The formaldehyde sensor 131 is used to obtain formaldehyde parameters, the PM2.5 detection sensor 132 is used to obtain PM2.5 parameters, and the temperature and humidity detection sensor 133 is used to obtain temperature and humidity parameters. The controller 14 generates an air quality index based on the formaldehyde parameters, PM2.5 parameters, and temperature and humidity parameters, and then the controller 14 controls the working state of the sterilization device 10 according to the air quality index.

[0068] In some optional embodiments, the controller 14 may control the working state of the sterilization device 10 through the following steps:

[0069] Determine the quality interval in which the air quality index is located. In this embodiment, two quality intervals, a first quality interval and a second quality interval, can be preset, wherein the air quality corresponding to the second quality interval is higher than the air quality corresponding to the first quality interval. If, after judgment, it is determined that the air quality index is in the preset first quality interval, it means that the air quality is low, and the sterilization equipment can be controlled to perform sterilization work to improve the air quality; if the air quality index is in the preset second quality interval, that is, the air quality is high, the sterilization equipment is controlled to stop the sterilization work to save power resources.

[0070] Furthermore, the first quality interval includes a first sub-quality interval and a second sub-quality interval, and the air quality corresponding to the second sub-quality interval is higher than the air quality corresponding to the first sub-quality interval. If it is further determined that the air quality index is in the first sub-quality interval, the sterilization device is controlled to perform sterilization at a preset first power; if the air quality index is in the second sub-quality interval, the sterilization device is controlled to perform sterilization at a preset second power. Among them, the first power is greater than the second power, that is, if the air quality index is in the first sub-quality interval, it means that the air quality is relatively poor, and the power of the sterilization device can be increased to improve the sterilization effect; if the air quality index is in the second sub-quality interval, it means that the air quality is relatively good, and the power of the sterilization device can be reduced to save electric energy.

[0071] Figure 6 It is a flow chart provided by an embodiment of the sterilization control method of the present invention.

[0072] Based on a general inventive concept, this embodiment further provides a sterilization control method, which is applied to the sterilization volute of any of the above embodiments. The sterilization volute includes a sterilization device.

[0073] like Figure 6 As shown, the method of this embodiment may specifically include the following steps:

[0074] S21. Obtain air quality index.

[0075] In this embodiment, the air quality index may be obtained first.

[0076] The air quality index can be obtained through various ways. For example, the air quality index can be obtained by accessing the Internet and using the local weather forecast; data can also be exchanged with air detection equipment installed in the same area to obtain the air quality index calculated by the air detection equipment installed in the same area; an air detection equipment can also be installed on the sterilization volute, and the air quality index can be detected by the air detection equipment installed on the sterilization volute, which is not limited in this embodiment.

[0077] In some optional embodiments, an air detection device is provided on the sterilization volute. The air detection device may include at least one of a formaldehyde sensor, a PM2.5 detection sensor, and a temperature and humidity detection sensor. Among them, the formaldehyde sensor 131 is used to obtain formaldehyde parameters, the PM2.5 detection sensor 132 is used to obtain PM2.5 parameters, and the temperature and humidity detection sensor 133 is used to obtain temperature and humidity parameters. In this embodiment, at least one of the formaldehyde parameters, PM2.5 parameters, and temperature and humidity parameters can be obtained; based on at least one of the formaldehyde parameters, PM2.5 parameters, and temperature and humidity parameters, an air quality index is generated. The air quality index is obtained by combining at least formaldehyde parameters, PM2.5 parameters, and temperature and humidity parameters. It should be noted that determining the air quality index based on formaldehyde parameters, PM2.5 parameters, and temperature and humidity parameters is a very mature technical means in this field, and this embodiment will not be repeated.

[0078] S22. Control the working status of the sterilization equipment according to the air quality index.

[0079] Specifically, the working state of the sterilization equipment can be controlled through the following steps:

[0080] Step 1: Determine the quality range of the air quality index;

[0081] Step 2: If the air quality index is in a preset first quality interval, the sterilization equipment is controlled to perform sterilization work; if the air quality index is in a preset second quality interval, the sterilization equipment is controlled to stop sterilization work.

[0082] Specifically, this embodiment can preset two quality intervals, and the air quality corresponding to the second quality interval is higher than the air quality corresponding to the first quality interval. If it is determined through judgment that the air quality index is in the preset first quality interval, it means that the air quality is low, and the sterilization equipment can be controlled to perform sterilization work to improve the air quality; if the air quality index is in the preset second quality interval, that is, the air quality is high, the sterilization equipment is controlled to stop the sterilization work to save electricity resources.

[0083] In some optional embodiments, the first mass interval includes a first sub-mass interval and a second sub-mass interval; if the air quality is in the first sub-mass interval, the sterilization equipment is controlled to perform sterilization work at a preset first power; if the air quality is in the second sub-mass interval, the sterilization equipment is controlled to perform sterilization work at a preset second power; wherein the first power is greater than the second power, and the air quality corresponding to the second sub-mass interval is higher than the air quality corresponding to the first sub-mass interval.

[0084] Specifically, if the air quality index is in the first sub-quality interval, it means that the air quality is relatively poor, and the power of the sterilization equipment can be increased to improve the sterilization effect and ensure people's health; if the air quality index is in the second sub-quality interval, it means that the air quality is relatively good, and the power of the sterilization equipment can be reduced to save electric energy.

[0085] The user can set the air quality index corresponding to each quality interval according to the actual situation in the area, and this embodiment does not limit this.

[0086] In some optional embodiments, the higher the calculated air quality index value, the higher the air quality. The air quality index corresponding to the first sub-quality interval includes 0-40; the air quality index corresponding to the second sub-quality interval includes 40-60; the air quality index corresponding to the second quality interval is greater than 60.

[0087] Specifically, the air detection device can detect the air quality index in real time. If the air quality index is greater than 60, it means that the air quality is high and the air quality index is in the second quality interval. The sterilization equipment is controlled to stop running to save electricity. If the air quality index is less than 60, it means that the air quality index may be in the first sub-quality interval or the second sub-quality interval. It is further determined whether the air quality index is greater than 40. If the air quality index is greater than 40, it means that the air quality is high and the air quality index is in the second sub-quality interval. The sterilization equipment is controlled to run in a low-power state to save electricity while sterilizing. If the air quality index is less than 40, it means that the air quality is low and the air quality index is in the first sub-quality interval. The sterilization equipment is controlled to run in a high-power state to improve the sterilization effect.
