[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] refer to Figure 1-3 An ultraviolet (UV) disinfection vehicle includes a mobile frame 1, an operating table 2, a placement chamber 3, a UV lamp structure 4, a rotating shaft 5, an automatic reset structure 6, and a positioning structure 7. The mobile frame 1 serves as the support and moving component of the entire disinfection vehicle. The operating table 2 is mounted on the mobile frame 1 and integrates control circuitry and an interface, allowing control of the UV lamp structure's opening and closing, as well as adjustment of disinfection parameters. The placement chamber 3, also mounted on the mobile frame 1, houses the UV lamp structure 4. The UV lamp structure 4 is rotatably housed within the placement chamber 3 and electrically connected to the operating table 2 via a flexible cable. The operating table 2 controls the corresponding actions of the UV lamp structure 4, thereby achieving disinfection control of the disinfection vehicle. The rotating shaft 5 is rotatable. Located inside the placement chamber 3, the rotating shaft 5 is rotatably connected to the interior of the placement chamber 3 via a deep groove ball bearing. An ultraviolet lamp structure 4 is mounted on the rotating shaft 5. The ultraviolet lamp structure 4 can be adjusted in position using the rotating shaft 5 as its rotation center, thus meeting different disinfection needs. An automatic reset structure 6 is located between the ultraviolet lamp structure 4 and the placement chamber 3, providing an automatic reset driving force. After the ultraviolet lamp structure 4 rotates, it automatically resets to its initial position, achieving automatic storage of the ultraviolet lamp structure 4. A positioning structure 7 is located between the rotating shaft 5 and the placement chamber 3, enabling the positioning and locking of the ultraviolet lamp structure 4, facilitating its fixation at different angles and ensuring its positional accuracy.

[0034] In some embodiments, the mobile frame 1 includes a fixed frame 11 and multiple casters 12. The fixed frame 11 is provided with an operating table 2 and a placement compartment 3. The fixed frame 11 can be welded from high-strength aluminum alloy profiles and the surface is anodized. Multiple casters 12 are located at the bottom of the fixed frame 11 to facilitate the movement of the disinfection vehicle in different locations. There can be four casters 12, located at the four corners of the fixed frame 11. Silent casters can be used, and a dual braking system of foot brake + wheel brake can be provided to ensure that the disinfection vehicle is parked stably during operation.

[0035] In some embodiments, the placement compartment 3 includes a placement block 31, a rotating groove 32, and a protective door 33. The placement block 31 is mounted on the movable frame 1 and can be welded and fixed. It can be made of die-cast aluminum. The rotating groove 32 is located on the side of the placement block 31 away from the operating table 2, and a rotating shaft 5 is provided in the rotating groove 32 to provide space for the rotation of the ultraviolet lamp structure 4. One end of the protective door 33 is hinged to one end of the placement block 31 and can be connected by a damping hinge. The other end can be provided with a buckle. The protective door 33 can be made of transparent PC board, which can realize the opening and closing of the rotating groove 32 and play a protective role when the ultraviolet lamp structure is stored. This is the existing type and will not be described in detail here.

[0036] In some embodiments, the ultraviolet lamp structure 4 includes a rotating base 41, a partition strip 42, and two ultraviolet lamps 43. The rotating base 41 can be made of polyoxymethylene injection molding and is sleeved on the rotating shaft 5. The partition strip 42 is vertically arranged on the rotating base 41 and can be made of stainless steel. The two ultraviolet lamps 43 are symmetrically arranged on the rotating base 41 and can be low-pressure mercury lamps. The ultraviolet lamps 43 can be connected to the operating table 2 via flexible cables and are located on both sides of the partition strip 42 to ensure the stability of the center of gravity of the ultraviolet lamp structure 4, thereby making the ultraviolet lamp structure 4 more stable during rotation and storage. At the same time, different disinfection effects can be achieved by controlling the opening and closing of the two ultraviolet lamps 43. A gap can be left between the partition strip 42 and the ultraviolet lamps 43 to ensure heat dissipation of the ultraviolet lamps 43.

[0037] In some embodiments, the automatic reset structure 6 includes a torsion spring 61, which is sleeved on the rotating shaft 5 and located between the rotating seat 41 and the placement chamber 3. A connecting plate 34 can be fixedly provided on the inner wall of the rotating groove 32 and can be welded. One end of the rotating shaft 5 can be rotatably mounted on the inner wall of one side of the rotating groove 32 via a bearing, and the other end passes through the connecting plate 34 and can rotate on the connecting plate 34. The torsion spring 61 is sleeved on the rotating shaft 5, with one end fixed to the connecting plate 34 and the other end fixed to the rotating seat 41. Thus, when the ultraviolet lamp structure 4 rotates, the torsion spring 61 is compressed. When the torsion spring 61 is in its natural state, the elastic force of the torsion spring 61 can be used to achieve the automatic reset of the ultraviolet lamp structure 4.

[0038] In some embodiments, the automatic reset structure 6 further includes a rotary damper 62, which is disposed between the inner wall of the rotating groove 32 and the rotating shaft 5. One end of the rotary damper 62 is connected to the inner wall of the rotating groove 32, and its actuating end is coaxially connected to the rotating shaft 5. This can slow down the rotation speed of the ultraviolet lamp structure and avoid impact caused by excessive speed during the reset process.

[0039] In some embodiments, the automatic reset structure 6 further includes a buffer groove 63 and a buffer block 64. The buffer groove 63 is located at the bottom of the placement chamber 3, and a rubber buffer pad can be attached to the inner wall. The buffer block 64 is located at the end of the separator 42 away from the rotating shaft 5, and can be made of silicone material. It is inserted and matched with the buffer groove 63 to play a buffering role when the ultraviolet lamp structure 4 is reset, reduce collisions, and avoid damage to the ultraviolet lamp 43.

[0040] In some embodiments, the positioning structure 7 includes a ratchet 71 and a pawl 72. The ratchet 71 is coaxially sleeved on the rotating shaft 5, and the pawl 72 is rotatably disposed within the placement chamber 3 and engages with the ratchet 71. The engagement of the ratchet and pawl enables unidirectional rotation and positioning of the rotating shaft. An operating lever can be connected to the pawl 72 to rotate the pawl 72, thereby locking and releasing the ratchet 71, and locking and automatically resetting the position of the ultraviolet lamp structure 4.

[0041] The specific working principle is as follows:

[0042] When the ultraviolet disinfection cart is needed for disinfection, move the cart to the desired location using the movable frame 1. Open the protective door 33 and manually control the rotation of the ultraviolet lamp structure 4 to unfold it from the placement chamber 3. After rotating to the set angle, the pawl 72 engages with the ratchet to prevent the ultraviolet lamp structure 4 from shaking randomly. At the same time, the torsion spring 61 is compressed. Set the desired ultraviolet lamp 43 and operating parameters using the control panel 2 to begin disinfection.

[0043] After disinfection is completed, the pawl 72 is rotated by the operating lever, releasing it from the lock on the ratchet 71. Under the elastic restoring force of the torsion spring 61, the ultraviolet lamp structure 4 automatically returns to its original position in the placement chamber 3. The buffer block 64 is inserted into the buffer groove 63 to cushion the impact and reduce collisions. During this process, the rotation damper 62 operates, reducing the rotation speed of the ultraviolet lamp structure 4. The operating lever is released, and the protective door 33 is closed, completing the storage of the ultraviolet lamp structure 4.
