Description

Technical Field

[0001] The utility model relates to the technical field of sterilization, in particular to a sterilization device and a household appliance. Background Art

[0002] As users have higher and higher requirements for indoor air quality, air conditioners with sterilization functions are becoming more and more popular among consumers. At present, when sterilizing different strains of bacteria, air conditioners with sterilization lamps on the market can only meet the sterilization rate by increasing the sterilization time. For strains that are more resistant to ultraviolet rays, the time required is doubled, so energy consumption increases.

[0003] There is a sterilization device with adjustable focus, including a housing, a plane mirror, a lens, a motor and a screw, etc. The housing and the plane mirror form a closed space, and the motor drives the screw to rotate, thereby driving the lens to move, so as to adjust the distance between the lens and the light source and achieve zooming. However, since the material of the lens is usually fragile, it is very easy to cause damage to the lens in the process of the screw driving it to move. In addition, the lens will reduce the amount of light transmitted. The existing solution requires two lenses, the plane mirror and the lens, which will greatly reduce the amount of light transmitted, thus affecting the sterilization effect. Utility Model Content

[0004] The first purpose of the utility model is to provide a sterilization device, which can improve the sterilization intensity and achieve different sterilization effects by adjusting the focal length, while reducing energy consumption and extending the service life.

[0005] The second object of the utility model is to provide a household appliance adopting the above-mentioned sterilization device.

[0006] To achieve the above-mentioned first purpose, the utility model provides a sterilization device, including a spotlight cover, a focusing lens, a light source body and a focusing module. The inner wall of the spotlight cover is provided with a reflective surface, and the reflective surface is arranged toward the focusing lens; the focusing lens is installed at the open end of the spotlight cover, and the spotlight cover and the focusing lens form a light source accommodating cavity, and the light source body is located in the light source accommodating cavity and is arranged toward the focusing lens; the focusing module includes a driving member and an adjusting rod, and the driving member is installed on the spotlight cover, and the driving member is connected to the light source body through the adjusting rod, and the driving member drives the adjusting rod to move, and the adjusting rod drives the light source body to approach or move away from the focusing lens.

[0007] It can be seen from the above scheme that the adjustment rod is driven to move by the driving member, and the adjustment rod drives the light source body to move closer to or away from the focusing lens, thereby adjusting the focal length of the sterilization device. When facing UV-tolerant bacteria, the adjustment rod drives the light source body away from the focusing lens, and the light converges to the focus, directly focusing the sterilizing ultraviolet to kill it, thereby increasing the intensity of ultraviolet light and sterilization ability and reducing the sterilization time; when strong sterilization is not required, that is, when facing ordinary bacteria, the adjustment rod drives the light source body close to the focusing lens, so that the light is dispersed, thereby obtaining a larger sterilization area, saving sterilization time and reducing sterilization energy consumption. In addition, since the light source body of the sterilization device only passes through a layer of lens, the light transmittance is large, ensuring the sterilization effect. Moreover, the driving member drives the light source body to move instead of the lens, and the light source body usually includes a high-strength support shell, so that it will not cause damage to the lens, and can extend the service life of the sterilization device.

[0008] A preferred solution is that both the spotlight cover and the spotlight lens are in the shape of long strips; the open end of the spotlight cover is provided with a mounting rail extending along the length direction of the spotlight cover, and the edge of the spotlight lens is slidably matched with the mounting rail.

[0009] It can be seen that the sliding fit between the edge of the condenser lens and the mounting guide rail can ensure a stable connection between the condenser lens and the spotlight cover.

[0010] A further solution is that an insertion port is provided at one end of the mounting rail, and the focusing lens can be inserted into the mounting rail from the insertion port. The insertion port is provided with a fixing block, and the fixing block limits the mounting rail in the extension direction of the mounting rail.

[0011] It can be seen that the provision of the insertion port facilitates the assembly of the focusing lens and the spotlight cover, and the provision of the fixing block facilitates the limiting fixation of the focusing lens after assembly to prevent sliding and dislocation after assembly.

[0012] A further solution is that the insertion port is further provided with a T-shaped slide groove, and the fixing block is provided with a T-shaped slide rail, and the slide rail and the slide groove are slidably matched along an extension direction perpendicular to the installation guide rail.

[0013] It can be seen that since the installation direction of the fixing block is perpendicular to the installation direction of the mounting rail, the installation of the fixing block is facilitated.

[0014] A preferred solution is that the sterilization device also includes a guide rod, which is arranged at the end of the light source body and perpendicular to the extension direction of the light source body, and the guide rod is arranged parallel to the adjustment rod; a guide hole is opened on the spotlight cover, and the guide hole and the guide rod slide together along the moving direction of the light source body.

[0015] It can be seen that the guide rod is used for guiding to ensure the stable movement of the light source body.

[0016] A further solution is that the number of guide rods is more than two, and at least one guide rod is respectively arranged at both ends of the light source body in the length direction. The adjustment rod is arranged in the middle of the spotlight cover in the length direction.

[0017] It can be seen that the multiple guide rods can ensure the force balance at both ends of the light source body, further improving the stability of the power supply movement.

[0018] A further solution is that a connecting portion is provided at one end of the guide rod, a mounting groove is provided on the connecting portion and matches with the light source body in a limiting manner, and the mounting groove and the light source body are plugged and matched along the extension direction of the light source body.

[0019] It can be seen that the insertion direction of the installation groove and the light source body is perpendicular to the moving direction of the light source body, ensuring the stability of the connection between the guide rod and the light source body. Even if the guide rod drives the light source body to move continuously, the two will not become loose.

[0020] A preferred solution is that the driving shaft of the driving member is provided with a gear, the adjusting rod is provided with a rack portion, and the gear and the rack portion are meshed. The driving member is arranged on the end wall of the spotlight cover away from the opening end.

[0021] A preferred solution is that a slot is provided at one end of the adjustment rod, and the light source body cooperates with the slot in an upper limit position in the moving direction of the light source body.

[0022] This shows that the stability of the connection between the adjustment rod and the light source body is ensured.

[0023] To achieve the above second purpose, the utility model provides a household appliance, comprising the above sterilization device. BRIEF DESCRIPTION OF THE DRAWINGS
