Description

Technical Field

[0001] This invention relates to the field of ultraviolet lamp technology, specifically to an ultraviolet lamp timer. Background Technology

[0002] An ultraviolet lamp is a device that emits ultraviolet light. It is an essential tool for observing the fluorescence and phosphorescence characteristics of samples and is also a physical means of sterilization and disinfection.

[0003] While existing ultraviolet lamps can sterilize and disinfect objects during actual use, the temperature of the lamp tube increases significantly after prolonged use. This high temperature may cause the adhesive used to bond and cure the lamp tube to its electrodes to melt, resulting in mercury vapor leaking out of the lamp tube during use. If this is not dealt with in time, the mercury vapor released into the environment may cause poisoning and affect human health.

[0004] Therefore, a new type of ultraviolet lamp timer is needed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an ultraviolet lamp timer to solve the problem of mercury vapor leakage from ultraviolet lamps, which cannot be dealt with in time and thus leads to human poisoning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultraviolet lamp timer, comprising a housing, a double-ring connecting block at the bottom of the housing, annular grooves on both sides of the double-ring connecting block, a rectangular hole between the inner walls of the two annular grooves, a cylindrical hole at the top of the inner wall of the rectangular hole, multiple air inlets evenly distributed on the inner walls of the two annular grooves, a single-hole block fixed on both sides of the two double-ring connecting blocks, mercury vapor sensors installed on both sides of the inner walls of the double-ring connecting blocks, a controller installed at the bottom of the inner wall of the housing, a miniature fan installed at the bottom of the inner wall of the housing, an air inlet pipe installed at the input end of the miniature fan, an air outlet pipe installed at the output end of the miniature fan, a concave block fixed inside the housing, a first mounting hole on the other side of the inner wall of the concave block, an activated carbon filter installed at the input end of the first mounting hole, a miniature pressure relief valve installed at the output end of the first mounting hole, and a sealing plate installed at the top of the concave block.

[0007] Preferably, the top of the double-ring connecting block extends through the bottom of the housing and extends into the interior of the housing. The controller is electrically connected to the micro fan, so that the micro fan can be started or stopped under the control of the controller.

[0008] Preferably, the input end of the air inlet pipe is connected to the top of the double-ring connecting block, the input end of the air outlet pipe movably passes through one side of the inner wall of the concave block, and the controller is electrically connected to two mercury vapor sensors respectively, so that under the action of the mercury vapor sensors, the mercury vapor data overflowing from both ends of the tube body of the ultraviolet lamp tube, which are respectively connected to two electrodes, can be collected.

[0009] Preferably, multiple rectangular plates are fixedly distributed at equal intervals on the front and rear surfaces of the double-ring connecting block. Each rectangular plate has a fixing bolt threaded through its bottom, and one end of each fixing bolt is threaded to the bottom of the housing. This allows the double-ring connecting block to be installed on the housing with the cooperation of the fixing bolt and the rectangular plate.

[0010] Preferably, two symmetrical lamp holders are installed on the bottom of the inner wall of the housing, and the bottom of both lamp holders moves through the bottom of the inner wall of the housing. A control switch is installed on the bottom of the inner wall of the housing, so that the lamp body and the timer body can be started or stopped under the action of the control switch.

[0012] Preferably, a starter mounting base is installed on the inner wall of the housing, and a starter body is installed inside the starter mounting base. The front surface of the starter body can move through the inner wall of the housing, so that the lamp body can be lit after being powered on by the action of the starter body.

[0013] Preferably, a lamp body is installed between the opposite sides of the two lamp holders, and mounting blocks are fixed on both sides of the housing near the top. A cover is installed on the top of the housing, which facilitates the protection of the internal components of the housing through the cooperation of the cover and the housing.

[0029] according to Figure 1 - Figure 5 As shown, multiple rectangular plates 3 are fixed at equal intervals on the front and rear surfaces of the double-ring connecting block 2. Each rectangular plate 3 has a fixing bolt 28 threaded through its bottom. One end of each fixing bolt 28 is threaded to the bottom of the housing 1, so that the double-ring connecting block 2 can be installed on the housing 1 with the cooperation of the fixing bolt 28 and the rectangular plate 3.

[0030] according to Figure 1 - Figure 3 and Figure 7 As shown, two symmetrical lamp holders 16 are installed on the bottom of the inner wall of the housing 1, and the bottom of both lamp holders 16 can move through the bottom of the inner wall of the housing 1. A control switch 17 is installed on the bottom of the inner wall of the housing 1, so that the lamp body 23 and the timer body 19 can be started or stopped under the action of the control switch 17.

[0031] according to Figure 1 - Figure 3 and Figure 7 As shown, both buttons of the control switch 17 move through the inner wall of the housing 1. The inner wall of the housing 1 has a second mounting hole 18. The timer body 19 is installed inside the second mounting hole 18. The ballast 20 is installed at the bottom of the inner wall of the housing 1, so that the lamp body 23 can be used for timing under the action of the timer body 19.

[0032] according to Figure 1 - Figure 3 and Figure 7As shown, a starter mounting base 22 is installed on the inner wall of the housing 1. A starter body 21 is installed inside the starter mounting base 22. The front surface of the starter body 21 can move through the inner wall of the housing 1. The control switch 17 is electrically connected to the timer body 19. The timer body 19 is electrically connected to the ballast 20. The ballast 20 is electrically connected to one of the lamp holders 16 through a first wire. One of the lamp holders 16 is electrically connected to the starter mounting base 22 through a second wire. The starter mounting base 22 is electrically connected to the other lamp holder 16 through a third wire. This allows the lamp body 23 to be lit after being powered on by the starter body 21.

[0033] according to Figure 1 - Figure 3 , Figure 5 and Figure 7 As shown, a lamp tube body 23 is installed between the opposite sides of the two lamp holders 16. Mounting blocks 24 are fixed on both sides of the housing 1 near the top. A cover 29 is installed on the top of the housing 1, which facilitates the protection of the internal components of the housing 1 with the cooperation of the cover 29 and the housing 1.

[0034] The overall effect of the mechanism is as follows: When the ultraviolet lamp body 23 is needed to disinfect an object, the lamp body 23 is directly installed between the two lamp holders 16, and the starter body 21 is installed on the starter mounting base 22. An appropriate amount of sulfur powder is placed inside the concave block 11. Then, the entire ultraviolet lamp is installed in the desired position using the mounting block 24. Afterwards, the control switch 17 is connected to the external power supply and powered on. Figure 7As shown, when the ultraviolet lamp body 23 needs to be lit, simply press the start switch on the control switch 17. The timer body 19 will then start and begin timing. The lighting time for the ultraviolet lamp body 23 can be set. Simultaneously, with the cooperation of the ballast 20, the two lamp holders 16, the starter mounting base 22, and the starter body 21, the ultraviolet lamp body 23 can be directly started. While the ultraviolet lamp body 23 remains lit, the timer body 19 will also continuously time. When the timer body 19 reaches its limit, it will issue an alarm. At this point, the operator can directly extinguish the ultraviolet lamp body 23, and the timer body 19 will also turn off. When the tube body 23 is lit for an extended period, the adhesive used to bond and cure the two electrodes at both ends of the ultraviolet lamp tube body 23 will melt, causing mercury vapor to escape from the inside of the ultraviolet lamp tube body 23. As the mercury vapor escapes from the inside of the ultraviolet lamp tube body 23, the mercury vapor sensor 6 will come into contact with it and transmit the collected data as an electrical signal to the controller 7. The controller 7 will then analyze and process the received electrical signal. When the collected value exceeds the value set internally by the controller 7, the controller 7 will directly control the micro fan 8 to start. The started micro fan 8 will then provide suction to the input end of the connected air intake pipe 9. With the cooperation of the cylindrical hole 27, rectangular hole 26, double-ring connecting block 2, and annular groove 25, all the input ends of the air inlets 4 will directly obtain suction. At this time, the input end of each air inlet 4 that obtains suction will draw mercury vapor overflowing from the two ends of the tube body 23 connected to the two electrodes into the corresponding annular groove 25. Then, the mercury vapor entering the two annular grooves 25 will gather together into the rectangular hole 26, then into the cylindrical hole 27, and then into the air inlet pipe 9. Then, with the cooperation of the micro fan 8 and the air outlet pipe 10, the drawn mercury vapor will be directly sprayed out from the output end of the air outlet pipe 10 into the concave block 11. When the mercury vapor reaches the inside of the concave block 11, the mercury vapor... The sulfur powder inside the concave block 11 reacts with the sulfur powder to produce mercury sulfide, thus removing mercury vapor. When the internal pressure of the concave block 11 is too high, the pressure inside the concave block 11 can be released to a suitable range through the cooperation of the miniature pressure relief valve 12 and the first mounting hole 14. The activated carbon filter 15 prevents unreacted sulfur powder and the mercury sulfide powder formed after the reaction from entering the miniature pressure relief valve 12, avoiding blockage. When there is no mercury vapor overflowing from the two electrode connections at both ends of the ultraviolet lamp tube body 23, the controller 7 can shut off the miniature fan 8. When it is necessary to clean the mercury sulfide formed inside the concave block 11 and replace it with new sulfur powder...At this point, simply remove the entire UV lamp from the desired location, then open the cover 29, remove the sealing plate 13, and it can be replaced.

[0035] Among them, the mercury vapor sensor 6, controller 7, miniature fan 8, miniature pressure relief valve 12, lamp holder 16, control switch 17, timer body 19, ballast 20 (EB-Ci), starter body 21 (S10-C), starter mounting base 22, and lamp body 23 (ZSZ-1) are all existing technologies and will not be explained in detail here.

[0036] The timer body 19 is mainly composed of several parts, including a timing circuit, a decoding and display circuit, a pulse generation circuit, an alarm module, and a control circuit, which can realize timed alarm operation.
