Description

Technical Field

[0001] The present application relates to the technical field of water sterilization equipment, and in particular to an ultraviolet LED sterilization device. Background Art

[0002] LED ultraviolet sterilization is a method of destroying the DNA structure of microorganisms through ultraviolet radiation, thereby causing the bacteria to die immediately or be unable to reproduce to achieve the purpose of disinfection and sterilization. Because LED ultraviolet sterilization is a purely physical disinfection method, there is no secondary pollution. At the same time, ultraviolet rays can disinfect various microorganisms, making LED ultraviolet sterilization broad-spectrum. Therefore, with the introduction of various newly designed ultraviolet lamps, the application scope of ultraviolet sterilization is also expanding;

[0003] Among them, water sterilization is one of the most mature and effective applications of UV LED. Through high-power UV irradiation, the water flowing through the sterilization module can be efficiently and instantly sterilized to a sterile level or a level with extremely low bacteria content, thereby effectively improving the hygiene and safety of people's use of water.

[0004] However, the water flow in the water valve will change according to people's actual usage status, and LED ultraviolet sterilization needs to ensure a certain irradiation intensity to achieve the purpose of effective sterilization, and accompanied by the attenuation of light intensity, when the water flow is too large, the weaker ultraviolet irradiation intensity cannot meet the effective sterilization requirements, and when the water flow is too small, the stronger ultraviolet irradiation intensity will increase the energy consumption of the ultraviolet LED sterilization module, and the stability and reliability are poor.

[0005] Therefore, there is an urgent need for an over-flow LED ultraviolet sterilization device to solve the defects existing in the above-mentioned existing LED ultraviolet sterilization module during actual use. Summary of the invention

[0006] The present application proposes a UV LED sterilization device, which has the ability to automatically adjust the irradiation intensity of the LED UV sterilization module thereon according to the water flow rate, so that it has the advantages of better sterilization effect on the water flow and lower energy consumption, and higher stability and reliability. It is used to solve the problem that when the water flow is too large, the weaker UV irradiation intensity cannot meet the effective sterilization requirements, and when the water flow is too small, the stronger UV irradiation intensity will increase the energy consumption of the UV LED sterilization module.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a UV LED sterilization device, comprising an outer valve body, an elastic capsule fixedly sleeved in the middle of the inner cavity of the outer valve body, and a linkage component movably sleeved on the top of the chamber formed by the elastic capsule and the outer valve body, and a seal is formed on the bottom of the formed chamber through the linkage component, an elastic component is provided at the top of the linkage component, and the linkage component is elastically connected to the outer valve body through the elastic component, a conductor is provided at the bottom of the inner wall of the linkage component, and a sliding variable resistance wire is provided in the middle of the outer surface of the elastic capsule, and at the same time, an ultraviolet lamp group is fixedly installed at the bottom of the inner wall of the outer valve body, and a series circuit is formed between the ultraviolet lamp group, the conductor, the sliding variable resistance wire and the external power supply.

[0008] Furthermore, a connecting hole is provided at the top end of the inner part of the outer valve body, wherein one end of the connecting hole is connected to the top end of the chamber formed by the outer valve body and the elastic bag, and the other end of the connecting hole is connected to the outer surface of the outer valve body.

[0009] Furthermore, the exterior of the connecting hole is configured as an inverted U-shaped structure, so that when air enters the chamber formed by the outer valve body and the elastic bag through the connecting hole, the water vapor therein may condense in the process of contacting with the inner wall of the connecting hole and be discharged through the connecting hole.

[0010] Furthermore, a protrusion is provided on the outside of the linkage assembly, and is used to limit the downward displacement of the linkage assembly under the elastic force of the elastic component. At the same time, a through groove is provided on the inside of the outer valve body, and the connecting hole and the top of the chamber formed by the outer valve body and the elastic bag are connected through the through groove.

[0011] Furthermore, the conductor and the sliding variable resistance wire are in a non-contact state in an initial state, and when no water flows through the outer valve body, the ultraviolet lamp group is in a non-conductive state.

[0012] Furthermore, an inner annular groove arranged obliquely is provided at the bottom of the inner wall of the outer valve body and above the ultraviolet lamp group, so that when water flows in the inner cavity of the outer valve body, the ultraviolet lamp group can be cooled by the water temporarily stored in the inner annular groove.

[0013] The present invention application has the following technical effects:

[0014] The present application provides an ultraviolet LED sterilization device, in which the elastic capsule and the structure thereon are arranged so that the relative contact position between the conductor and the sliding variable resistance wire changes through the extrusion deformation of the elastic capsule caused by the water flow flowing in the outer valve body, thereby adjusting the irradiation intensity of the ultraviolet lamp group on the water flow flowing in the outer valve body, so as to ensure a good sterilization effect while having low energy consumption, high stability and reliability.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] like Figure 1 As shown, a UV LED sterilization device comprises an outer valve body 1 whose top is threadedly connected to the end of a water outlet pipe, an elastic capsule 2 is fixedly sleeved in the middle of the inner cavity of the outer valve body 1, and a linkage component 3 is movably sleeved on the top of the chamber formed by the elastic capsule 2 and the outer valve body 1, and the bottom of the formed chamber is sealed by the linkage component 3, and then when the bottom end of the elastic capsule 2 is squeezed, the linkage component 3 can be driven to move upward under the action of gas pressure, and an elastic component 4 is provided at the top of the linkage component 3, and the linkage component 3 is elastically connected to the outer valve body 1 through the elastic component 4, Then, when the bottom end of the elastic capsule 2 is no longer squeezed, the elastic force of the elastic component 4 can automatically drive the linkage assembly 3 to move downward and return to its initial position. A conductor 5 is provided at the bottom of the inner wall of the linkage assembly 3, and a sliding variable resistance wire 6 is provided in the middle of the outer surface of the elastic capsule 2. At the same time, an ultraviolet lamp group 9 is fixedly installed at the bottom of the inner wall of the outer valve body 1, and a series circuit is formed between the ultraviolet lamp group 9, the conductor 5, the sliding variable resistance wire 6 and the external power supply, and then the light intensity of the ultraviolet lamp group 9 is controlled by the relative contact position between the conductor 5 and the sliding variable resistance wire 6:

[0023] When the water flow through the outer valve body 1 is large, the extrusion force on the elastic capsule 2 is large, so that the deformation produced is large, and the displacement of the linkage assembly 3 upward is large, and the conduction resistance between the conductor 5 and the sliding variable resistance wire 6 is small, and the ultraviolet irradiation intensity of the ultraviolet lamp group 9 is relatively strong, and the sterilization effect on the large water flow flowing through the outer valve body 1 is better;

[0024] When the water flow through the outer valve body 1 is small, the extrusion pressure on the elastic bag 2 is small, so that the deformation produced is smaller, and the upward displacement of the linkage component 3 is forced to be smaller, and the conduction resistance between the conductor 5 and the sliding variable resistance wire 6 is larger, and the ultraviolet irradiation intensity in the ultraviolet lamp group 9 is relatively weak, while ensuring the sterilization effect, the energy consumption of the ultraviolet lamp group 9 is effectively reduced.

[0025] like Figure 1 As shown, in the present technical solution, a plurality of groups of connecting holes 7 arranged in a circular array are provided at the top of the inner part of the outer valve body 1, wherein one end of the connecting hole 7 is connected to the top of the chamber formed by the outer valve body 1 and the elastic bag 2, and the other end of the connecting hole 7 is connected to the outer surface of the outer valve body 1, thereby balancing the gas pressure in the chamber formed by the outer valve body 1 and the elastic bag 2 during the up and down movement of the linkage assembly 3, thereby effectively ensuring the smoothness of the linkage assembly 3 during the up and down movement.

[0026] like Figure 1 As shown, in the present technical solution, the outside of the connecting hole 7 is set to an inverted U-shaped structure, so that when the air enters the chamber formed by the outer valve body 1 and the elastic bag 2 through the connecting hole 7, the water vapor therein can condense in the process of contacting with the inner wall of the connecting hole 7 and be discharged through the connecting hole 7.

[0027] like Figure 1 , Figure 3 As shown, in the present technical solution, a protrusion is provided on the outside of the linkage assembly 3, and is used to limit the downward displacement of the linkage assembly 3 under the elastic force of the elastic component 4. At the same time, a through groove 10 is provided on the inside of the outer valve body 1, and the connecting hole 7 and the top of the chamber formed by the outer valve body 1 and the elastic bag 2 are connected through the through groove 10.

[0028] In this technical solution, the conductor 5 and the sliding variable resistance wire 6 are in a non-contact state in the initial state, and when there is no water flowing through the outer valve body 1, the ultraviolet lamp group 9 is in a non-conductive state, further reducing the energy consumption of the ultraviolet lamp group 9 in the sterilization device.

[0029] like Figure 1As shown, in the present technical solution, an inner ring groove 8 arranged obliquely is provided at the bottom of the inner wall of the outer valve body 1 and above the ultraviolet lamp group 9, so that when water flows in the inner cavity of the outer valve body 1, the ultraviolet lamp group 9 can be cooled by the water temporarily stored in the inner ring groove 8.
