[0038] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0040] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0041] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] This application provides a refrigerator, including a cabinet and a pulse lamp module 1. A refrigerator compartment is formed within the cabinet, and multiple drawers are arranged within the refrigerator compartment along the height of the cabinet. The cabinet also includes multiple top panels, which are used to divide the refrigerator compartment space to form multiple spaces for installing drawers. The pulse lamp module 1 is installed at the bottom of the top panels to sterilize the food inside the drawers.

[0044] Please see Figure 1 and Figure 2 The pulse lamp module 1 includes a housing 10, a circuit board 20, a pulse lamp assembly 30, and two conductive supports 40. The housing 10 may include a base 110 and a top cover, with the top cover covering the base 110 to form a receiving cavity 110a. The housing 10 is provided with a window 110b communicating with the receiving cavity 110a and the outside. The window 110b may be located on the end face of the base 110 opposite to the top cover.

[0045] The housing 10 of the pulse lamp module 1 may include an independent top cover, which is installed on the bottom of the top plate. The connection between the two is not limited to snap-fit ​​connection, screw connection, etc. Of course, the base 110 can also be fixed to the bottom of the top plate of the refrigerator, so that the top plate serves as the top cover of the pulse lamp module 1. It should be noted that when the top plate is used directly as the top cover, the top plate needs to be made of high-temperature resistant material.

[0046] Please see Figure 3The circuit board 20 is installed within the receiving cavity 110a; the pulse lamp assembly 30 includes a light-emitting tube 310, which is installed within the receiving cavity 110a and emits light outward through a window 110b; the light-emitting tube 310 can use a pulsed inert gas lamp, such as a xenon lamp, which can emit light similar to the solar spectrum but with a stronger intensity, covering a wide spectral range from ultraviolet to infrared, and can effectively sterilize and disinfect different types of microorganisms. The pulsed inert gas lamp can release high-energy light within millimeter-level time, effectively ensuring food safety while delaying spoilage caused by microbial growth and extending the shelf life. This high-intensity light pulse can quickly destroy the cell structure of microorganisms, thereby achieving a rapid sterilization effect. Moreover, due to the extremely short processing time, the contact time with the surface of the food is also very limited, so it will not damage the quality of the food, maintaining its original flavor and nutritional value.

[0047] Please refer to the following: Figure 4 One end of one of the two conductive supports 40 is connected to the anode of the light-emitting tube 310, and the other end is connected to the circuit board 20. The other end of the two conductive supports 40 is connected to the cathode of the light-emitting tube 310, and the other end is connected to the circuit board 20. Thus, the two conductive supports 40 electrically connect and fix the light-emitting tube 310 to the circuit board 20. The rigidity and stability of the conductive supports 40 ensure that the light-emitting tube 310 and the circuit board 20 are relatively fixed, remaining stable even under vibration or external force, effectively preventing the tube from loosening or falling off during use. The electrical connection between the conductive supports 40 and the circuit board 20 ensures stable current transmission between the light-emitting tube 310 and the circuit board 20. In this application, using two conductive supports 40 to electrically connect and fix the light-emitting tube 310 to the circuit board 20 improves the installation stability and reliability of the light-emitting tube 310. Connecting the two conductive supports 40 to the circuit board 20 reduces the use of high-voltage terminals and improves safety compliance reliability.

[0048] It should be noted that the two ends of the conductive bracket 40 can be soldered to the light tube 310 and the circuit board 20 respectively. This connection method has high connection strength and conductivity. Alternatively, a curing adhesive can be used to fix the two ends of the conductive bracket 40 to the light tube 310 and the circuit board 20 respectively, or a clamp structure can be used to fix the two ends of the conductive bracket 40 to the light tube 310 and the circuit board 20 respectively. Here, this application does not impose specific restrictions on the connection method between the conductive bracket 40 and the light tube 310 and the circuit board 20.

[0049] Please see Figure 4In some embodiments, the pulse lamp assembly 30 further includes an outer lamp tube 320 and two rubber plugs 330. The outer lamp tube 320 covers the outside of the light-emitting tube 310, and the outer lamp tube 320 can be made of a light-transmitting material such as a quartz lamp tube. Openings 320a are provided on opposite sides of the outer lamp tube 320, and the two rubber plugs 330 respectively seal the openings 320a on opposite sides of the outer lamp tube 320. Two conductive supports 40 pass through the rubber plugs 330 and extend towards the circuit board 20. In this example, the outer lamp tube 320 covers the outside of the light-emitting tube 310, providing protection for the light-emitting tube 310. The two rubber plugs 330 seal the gap between the outer lamp tube 320 and the light-emitting tube 310, preventing dust, moisture, or other impurities from entering the internal space of the outer lamp tube 320 and affecting the brightness of the light-emitting tube 310.

[0050] Please see Figure 5 and Figure 6 In some embodiments, the rubber stopper 330 includes a base portion 331 and an outer cylinder 332 and an inner cylinder 333 connected to one side of the base portion 331 and spaced apart. The outer cylinder 332 and the inner cylinder 333 form slots 330a, into which opposite sides of the outer cover lamp tube 320 are inserted respectively. A wiring channel 330b is formed between the inner cylinder 333 and the base portion 331, through which the conductive support 40 extends towards the circuit board 20. The base portion 331 provides a stable foundation for the connection between the outer cylinder 332 and the inner cylinder 333, thus forming a slot 330a between them. The slot 330a allows opposite sides of the outer cover lamp tube 320 to be inserted, thereby achieving fixation and sealing of the outer cover lamp tube 320. The wiring channel 330b formed between the inner cylinder 333 and the base portion 331 facilitates the conductive support 40's access to the circuit board 20.

[0051] Please see Figure 4 The conductive support 40 includes a first connecting rod 410 and a second connecting rod 420 connected to each other. The end of the first connecting rod 410 away from the second connecting rod 420 is connected to the anode or cathode of the aforementioned light-emitting tube 310. The center line of the first connecting rod 410 and the center line of the second connecting rod 420 are set at an angle. In this way, the conductive support 40 can extend from inside the outer cover of the light tube 320 and extend towards the circuit board 20.

[0052] Please see Figure 5 and Figure 6Furthermore, the wiring channel 330b includes a first channel 330c and a second channel 330d that are connected. The first channel 330c is disposed in the inner cylinder 333, and the second channel 330d is disposed in the base portion 331. The extension directions of the first channel 330c and the second channel 330d are set at an angle. The first connecting rod 410 passes through the first channel 330c, and the second connecting rod 420 extends toward the circuit board 20 via the second channel 330d. The second channel 330d extends to the end face of the base portion 331 away from the outer cylinder 332. After the conductive bracket 40 extends outward from the first channel 330c and the second channel 330d, the conductive bracket 40 is bent and extends around the second channel 330d. In this way, the conductive bracket 40 can extend out from the outer lamp tube 320, and the second channel 330d can guide the wire bracket, which is conducive to bending the conductive bracket 40 and extending it toward the circuit board 20. This forms the first connecting rod 410 and the second connecting rod 420.

[0053] To facilitate the connection between the conductive bracket 40 and the circuit board 20, the conductive bracket 40 also includes a third connecting rod 430. One end of the third connecting rod 430 is connected to the end of the second connecting rod 420 away from the first connecting rod 410, and the other end is connected to the circuit board 20. The centerline of the third connecting rod 430 is set at an angle to the centerline of the second connecting rod 420. The plane containing the centerlines of the first connecting rod 410 and the second connecting rod 420 is perpendicular to the plane containing the centerlines of the second connecting rod 420 and the third connecting rod 430. The pulse lamp assembly 30 and the circuit board 20 are arranged at intervals in a roughly horizontal direction. The first connecting rod 410 facilitates the extension of the conductive bracket 40 from inside the outer lamp tube 320, the second connecting rod 420 facilitates the extension of the conductive bracket 40 horizontally towards the circuit board 20, and the third connecting rod 430 facilitates the extension of the conductive bracket 40 vertically towards the circuit board 20, so that the conductive bracket 40 can be inserted into the fixing hole of the circuit board 20 and connected to the circuit board 20.

[0054] Please see Figure 5 and Figure 6 In some embodiments, the base portion 331 is provided with a through hole 330e for a connecting slot 330a and a second channel 330d; the pulse lamp assembly 30 also includes a trigger wire 50, the light-emitting tube 310 is a xenon lamp tube, one end of the trigger wire 50 is wound around the outside of the xenon lamp tube, and the other end of the trigger wire 50 passes through the through hole 330e and extends toward the circuit board 20 via the second channel 330d, and is electrically connected to the circuit board 20. The connection between the trigger wire 50 and the circuit board 20 can be set with reference to the connection between the conductive support 40 and the circuit board 20 described above.

[0055] The anode and cathode of the light-emitting tube 310 are connected to the circuit board 20 via a conductive bracket 40. When the pulse lamp assembly 30 is working, the capacitor on the circuit board 20 is charged. When the capacitor is fully charged, it discharges instantaneously, generating high voltage and high current. This high voltage and high current are transmitted to the anode and cathode of the xenon lamp tube through the conductive bracket 40, causing the inert gas inside the xenon lamp tube to undergo avalanche ionization. The ionized inert gas converts and releases electrical energy in the form of high-intensity light radiation, while generating heat. This high-intensity light radiation and heat disinfect germs and microorganisms on objects, achieving a sterilization effect. The trigger wire 50 is wound around the outside of the xenon lamp tube. When the capacitor discharges, the trigger wire 50 first receives a high-voltage pulse. This high-voltage pulse causes the inert gas (such as xenon) near the trigger wire 50 to ionize, forming initial electrons and ions; this process is called pre-ionization. The generation of pre-ionization lowers the voltage threshold for gas breakdown inside the xenon lamp tube. Without the trigger wire 50, a higher voltage is required to ionize and break down the gas inside the xenon lamp tube. The presence of the trigger wire 50 makes this process easier and more reliable. Once the gas inside the xenon lamp tube is broken down, a discharge channel is formed. When current flows through the discharge channel, the xenon lamp tube emits high-intensity light radiation, which can be used not only for lighting but also for sterilization and disinfection.

[0056] Understandably, the wire hole 330e is located in the slot 330a and allows the trigger wire 50 to extend from the outer lamp tube 320. The first channel 330c is located in the inner cylinder 333 and allows the conductive bracket 40 to extend from the outer lamp tube 320. This allows the trigger wire 50 and the conductive bracket 40 to maintain a distance, thus achieving an insulating effect.

[0057] Furthermore, the slot 330a is used for the insertion of both ends of the outer cover lamp tube 320, and the trigger wire 50 passes through the slot 330a and the wire hole 330e in sequence, and finally extends from the second channel 330d to the circuit board 20. In order to avoid the trigger wire 50 and the outer cover lamp tube 320 being squeezed at the slot 330a, the inner cylinder 333 is provided with a relief groove 330f that communicates with the slot 330a on the side wall near the slot 330a. At least part of the trigger wire 50 is embedded in the relief groove 330f, which facilitates the installation of the trigger wire 50 and the outer cover lamp tube 320.

[0058] Specifically, the assembly process of this application involves first welding two conductive supports 40 to the cathode and anode at both ends of the light-emitting tube 310, respectively. Then, one end of the trigger wire 50 is fitted onto the outside of the light-emitting tube 310. At this point, both conductive supports 40 are straight, and the portion of the trigger wire 50 extending from the light-emitting tube 310 is also straight. One end of the conductive support 40 is passed through the opening 320a, so that the light-emitting tube 310 is located inside the outer tube 320. Then, two rubber plugs 330 are passed through the conductive supports 40 and the trigger wire 50 and fixed to both ends of the outer tube 320 to seal the opening 320a. Next, the conductive supports 40 and the trigger wire 50 are bent multiple times to extend towards the circuit board 20 and welded in place, thereby enabling electrical connection and relative fixation with the circuit board 20. It can be understood that after bending the conductive supports 40, the aforementioned first connecting rod 410, second connecting rod 420, and third connecting rod 430 can be formed.

[0059] Please see Figure 5 and Figure 6 To improve the stability of the light tube 310 after installation, the rubber stopper 330 also includes a first protrusion 334 on one side of the outer wall of the outer cylinder 332. The first protrusion 334 is provided with a first support surface 3341, which rests on the bottom wall of the receiving cavity 110a. In this way, the rubber stopper 330 can not only seal the outer lamp tube 320, but also play a supporting role, reducing the force exerted by the conductive bracket 40 on the pulse lamp assembly 30, thereby improving the stability of the pulse lamp assembly 30 and the wire bracket after assembly, and thus improving the stability of operation.

[0060] Please see Figure 5 and Figure 6 Furthermore, the rubber stopper 330 also includes a second protrusion 335 disposed on the outer wall of the outer cylinder 332 on the side opposite to the first protrusion 334, and the second protrusion 335 is provided with a second support surface 3351; the pulse lamp module 1 also includes a fixing member 60, which is detachably connected to the housing 10 and abuts against the second support surface 3351. The connection method between the fixing member 60 and the housing 10 includes, but is not limited to, snap-fit ​​connection, screw connection, etc. The pulse lamp assembly 30 is sandwiched between the fixing member 60 and the housing 10. Through the action of the fixing member 60 and the housing 10 on the first support surface 3341 and the second support surface 3351 of the rubber stopper 330, the pulse lamp assembly 30 is securely installed in the receiving cavity 110a, ensuring that the pulse lamp assembly 30 is installed in the correct position, so that the light emitted by the pulse lamp assembly 30 can be stably emitted outward through the window 110b.

[0061] Please see Figure 2 and Figure 3The inner wall of the fastener 60 can be arched to facilitate the formation of a lampshade. The inner wall of the fastener 60 can be coated, affixed, or plated with a reflective layer to reflect the light emitted by the light-emitting tube 310 away from the window 110b, allowing it to exit from the window 110b. The reflective layer can be a metal reflective layer (such as aluminum, silver, etc.), a reflective film (such as glass bead-type reflective film, microprism-type reflective film, etc.), or a reflective coating (such as acrylic resin, reflective microspheres, etc.).

[0062] Please see Figure 3 In some embodiments, the housing 10 is provided with a first mounting area 111 and a second mounting area 112 spaced apart. The circuit board 20 is mounted in the first mounting area 111, and the pulse lamp assembly 30 is mounted in the second mounting area 112. In this way, the circuit board 20 and the pulse lamp assembly 30 are installed independently without interfering with each other, and the heat generated by the pulse lamp assembly 30 during operation can be prevented from affecting the operation of the circuit board 20.

[0063] This application may also include an electrical control box 70, which can be installed in the first installation area 111 mentioned above. The electrical control box 70 includes an upper shell 710, a lower shell 720, and a sealing ring 730. The upper shell 710 and the lower shell 720 are fastened together to form an installation space. The electrical control board is installed in the installation space. The upper shell 710 and / or the lower shell 720 may be provided with wiring holes on the side facing the pulse lamp assembly 30 so that the conductive bracket 40 and the trigger wire 50 can extend into the installation space and connect to the circuit board 20.
