Description

Technical Field

[0001] This invention belongs to the field of deodorization and disinfection technology, specifically relating to a deodorization and disinfection device for a body freezer. Background Technology

[0002] As a key piece of equipment for storing remains in funeral homes, hospital morgues and other places, the internal cleanliness, deodorization and disinfection of refrigerated cabinets are directly related to public health and safety, the dignity of the deceased and the occupational health of the operators. The cleaning and disinfection of body freezers mainly relies on manual cleaning methods. After wearing basic protective equipment, operators enter the cabinet or work at the cabinet opening for a long time, using rags, sponges or long-handled brushes soaked in disinfectant to manually wipe and scrub the inner walls, top and bottom of the cabinet. This poses a very high hygiene and safety risk, as operators are easily exposed to harmful pathogens inside the cabinet. Many existing cabinet cleaning devices focus on a single function. For example, some only have a fixed spray disinfection function and cannot remove physical stains; some use simple rotating brush heads but lack an effective pressurization mechanism and fitting design, resulting in poor cleaning effect on stubborn stains and biofilm; more importantly, most devices are of fixed size or have a limited adjustment range, making them unable to adapt to the internal dimensions of different brands and specifications of freezers, resulting in poor versatility. Summary of the Invention

[0003] The purpose of this invention is to provide a deodorizing and disinfecting device for a body freezer, which can be quickly adapted and firmly fixed through an adjustable frame, and achieves efficient deep cleaning by using a combination of walking and vibration motion. It also integrates spray disinfection, scraping pretreatment and magnetic quick-change modules to form an integrated cleaning system, which significantly improves versatility, cleaning efficiency and maintenance convenience.

[0004] The specific technical solution adopted by this invention is as follows: A deodorizing and disinfecting device for a body freezer includes an adjustment section that can be adjusted according to the internal dimensions of the freezer.

[0007] In a preferred embodiment, a rubber ring is fitted around the outer edge of the rotating wheel.

[0008] In a preferred embodiment, the washing unit includes a linkage, a follower wheel, a movable seat, a mounting plate, an elastic pressure member, a connecting steel cable, a connecting wheel, an elastic reset member, and a cleaning plate. The linkage is assembled on the outer edge of the connecting cylinder, and its inner side cooperates with the rotating wheel. The follower wheel is rotatably disposed inside the linkage and contacts the outer edge of the rotating wheel. One end of the movable seat is fixedly connected to the linkage. Two movable seats are provided. The mounting plate is slidably connected inside the movable seats. The elastic pressure member is disposed between the movable seats and the mounting plate. The connecting steel cable is disposed between the two movable seats and is fixedly connected to both movable seats. The connecting wheel is rotatably disposed inside the adjusting part, and its outer edge contacts the connecting steel cable. The elastic reset member is disposed between the corresponding movable seat and the adjusting part. The cleaning plate is fixedly disposed inside the movable seat.

[0009] In a preferred embodiment, the linkage component has a horizontal limiting groove inside, the inside of the limiting groove is slidably connected to the outer edge of the connecting cylinder, and the length of the limiting groove is the same as the eccentricity distance of the eccentric wheel.

[0010] In a preferred embodiment, the cleaning plate and the movable seat are fixed together by magnetic attraction, and a cleaning brush is fixedly installed on the outer side of the cleaning plate.

[0011] In a preferred embodiment, the adjusting unit includes a mounting base, a horizontal moving base, a vertical moving base, a follower base, an elastic pressing member, a water storage tank, a delivery pump, and a scraper. A drive motor is fixedly connected to the inner side of the mounting base. One side of the horizontal moving base is slidably connected to one side of the mounting base. The lower end of the vertical moving base is slidably connected to the upper end of the mounting base. One side of the follower base is slidably connected to the vertical moving base, and the lower end of the follower base is slidably connected to the horizontal moving base. Two elastic pressing members are provided, one between the mounting base and the vertical moving base, and the other between the horizontal moving base and the follower base. The water storage tank is fixedly connected to the interior of the mounting base. The delivery pump is fixedly connected to the interior of the mounting base, and its input end communicates with the interior of the water storage tank. A spray pipe is provided inside the mounting base, the horizontal moving base, the vertical moving base, and the follower base, and the spray pipe communicates with the output end of the delivery pump. The scraper is assembled at the mounting base, the horizontal moving base, the vertical moving base, and the follower base.

[0012] In a preferred embodiment, a limiting device is provided between the mounting base and the horizontal moving base, and between the vertical moving base and the follower base. The limiting device includes a positioning block, a sliding block, a limiting block, and an elastic fixing member. The positioning block is fixedly connected to the corresponding mounting base and the horizontal moving base. The interior of the sliding block is slidably connected to the positioning block.

[0013] In a preferred embodiment, one end of the limiting block is arc-shaped, and the interior of the positioning block has multiple equidistant positioning grooves that cooperate with one end of the limiting block.

[0014] The technical effects achieved by this invention are as follows: This invention, through an adjustment unit consisting of a mounting base, horizontal and vertical moving bases, and a follower base, combined with a unique limiting device, allows for quick manual stretching to fit the inner wall dimensions of the freezer. The continuous pressure provided by the elastic extrusion member and the mechanical self-locking of the limiting device ensure that no displacement or loosening occurs during subsequent cleaning operations. This solves the problem that cleaning tools or fixed equipment cannot be adapted to freezers of different sizes, thereby improving the applicability and deployment efficiency of the equipment. The drive unit of this invention uses a single motor to drive a drive shaft that integrates a rotating wheel and an eccentric wheel, realizing the reciprocating motion of the moving and brushing parts, which significantly improves the cleaning efficiency. At the same time, the elastic pressure-applying component in the brushing part ensures constant pressure contact between the brush head and the wall surface, while the connecting steel cable system ensures the synchronization of the multiple brush movements, achieving a deep cleaning effect far exceeding that of a single movement mode. This invention embeds a cleaning fluid storage, delivery, and spraying network into the adjustment unit, which can uniformly wet the surface before and after cleaning. The scraper plate mounted on the frame edge can pre-treat stains. In addition, the cleaning plate is fixed by magnetic attraction, which supports tool-free quick replacement and maintenance, greatly improving the convenience and hygiene safety of use.

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0021] Please see Figures 1 to 10 As shown, the present invention provides a deodorizing and disinfecting device for a body freezer, including an adjusting part 1, which can be adjusted according to the internal dimensions of the freezer; The adjustment unit 1 is equipped with a drive unit 2, which can move inside the adjustment unit 1. The drive unit 2 is equipped with a washing unit 3, which can drive the washing unit 3 to perform friction cleaning on the inside of the freezer by moving the drive unit 2. The drive unit 2 includes a drive motor 201, a drive rod 202, a connecting rod 203, a linkage rod 204, and a drive shaft 205. The drive motor 201 is fixedly connected to the interior of the adjustment unit 1. The drive rod 202 is fixedly connected to the output end of the drive motor 201. The interior of the connecting rod 203 is slidably connected to the outer edge of the drive rod 202. The middle part of the linkage rod 204 meshes with one end of the connecting rod 203 through a bevel gear. The interior of the drive shaft 205 is slidably connected to the outer edge of the linkage rod 204. The drive shaft 205 is slidably connected to the washing unit 3.

[0022] Specifically, after the device is placed in freezers of different sizes, the operator can manually adjust the frame size of the adjustment unit 1 to make its outline basically match the inner wall space of the freezer. When the drive motor 201 is powered on and starts to rotate, the drive rod 202 fixed to the output end of the drive motor 201 rotates synchronously. The rotation of the drive rod 202 drives the connecting rod 203, which is slidably connected to the outer edge, to rotate. The end of the connecting rod 203 meshes with the middle of the linkage rod 204 through a bevel gear. The rotation of the connecting rod 203 drives the linkage rod 204 to rotate together, thereby changing the power transmission direction of the drive motor 201 by 90 degrees. This causes the linkage rod 204 to start rotating around its own axis. The rotation of the linkage rod 204 transmits power to the drive shaft 205, which in turn transmits power to the washing unit 3. The washing unit 3 begins to move relative to the frame of the adjusting unit 1 and uses its cleaning components to apply pressure to the inner surface of the freezer and perform repeated friction cleaning.

[0023] Please see Figure 4 As shown, the outer edges of both the connecting rod 203 and the linkage rod 204 are polygonal. The connecting rod 203 and the driving rod 202 are slidably connected, and the linkage rod 204 and the connecting cylinder 2051 of the drive shaft 205 are also slidably connected. These slidably connected parts need to transmit rotational torque. Under the constraint of polygonal fit, each transmission rod can only slide axially and cannot rotate relative to the other in the circumferential direction, thus ensuring synchronous drive between the entire transmission components.

[0024] Please see Figure 4 and Figure 10 As shown, the drive shaft 205 includes a connecting cylinder 2051, a rotating wheel 2052, and an eccentric wheel 2053. The interior of the connecting cylinder 2051 is slidably connected to the outer edge of the linkage rod 204. The axis of the rotating wheel 2052 is fixedly connected to the outer edge of the connecting cylinder 2051. The outer edge of the rotating wheel 2052 is in contact with the cabinet wall. The interior of the eccentric wheel 2053 is fixedly connected to the outer edge of the connecting cylinder 2051, and the axis of the eccentric wheel 2053 is offset relative to the outer edge of the connecting cylinder 2051. The connecting cylinder 2051 obtains rotational power from the linkage rod 204, causing the rotating wheel 2052, which is coaxially fixed with the connecting cylinder 2051, to perform circular motion. When the outer edge of the rotating wheel 2052 is directly pressed against the inner wall of the freezer and rotates, the entire drive unit 2 and the washing unit 3 connected to it will move as a whole along the surface of the cabinet wall. The rotation of the connecting cylinder 2051 drives the eccentric wheel 2053 to rotate synchronously. The offset mass of the eccentric wheel 2053 generates a direct cam pushing force when rotating. The cam force of the eccentric wheel 2053 is transmitted to the brushing part 3, causing the brushing part 3 to oscillate at a high frequency, forming a highly efficient friction cleaning effect.

[0025] Please see Figure 4 and Figure 10As shown, a rubber ring is fitted around the outer edge of the rotating wheel 2052; Rubber material has a high coefficient of friction. The rubber ring can greatly increase the adhesion between the wheel rim and the inner wall of the freezer, ensuring that the torque of the drive motor 201 can be efficiently converted into traction force for linear movement, and avoiding the situation where insufficient friction will cause slippage and prevent movement.

[0026] Please see Figures 1 to 3 , Figure 5 as well as Figures 7 to 8 As shown, the washing unit 3 includes a linkage 301, a follower wheel 302, a movable seat 303, a mounting plate 304, an elastic pressure member 305, a connecting steel cable 306, a connecting wheel 307, an elastic reset member 308, and a washing plate 309. The linkage 301 is assembled on the outer edge of the connecting cylinder 2051, and the inner side of the linkage 301 cooperates with the rotating wheel 2052. The follower wheel 302 is rotatably disposed inside the linkage 301, and the outer edge of the follower wheel 302 contacts the outer edge of the rotating wheel 2052. One end of the movable seat 303 is fixedly connected to the linkage 301. The system consists of two mounting plates 304 that are slidably connected inside the movable seat 303. An elastic pressure member 305 is disposed between the movable seat 303 and the mounting plate 304. A connecting steel cable 306 is disposed between the two movable seats 303 and is fixedly connected to both movable seats 303. A connecting wheel 307 is rotatably disposed inside the adjustment part 1, and the outer edge of the connecting wheel 307 contacts the connecting steel cable 306. An elastic reset member 308 is disposed between the corresponding movable seat 303 and the adjustment part 1. A cleaning plate 309 is fixedly disposed inside the movable seat 303. When the connecting cylinder 2051 of the drive shaft 205 rotates, the rotating wheel 2052 in contact with the cabinet wall rotates, driving the entire washing section 3 to move along the cabinet wall. The synchronously rotating eccentric wheel 2053 transmits its eccentric motion to the linkage 301 through the connecting cylinder 2051. The limiting groove inside the linkage 301 constrains the circumferential motion of the eccentric wheel 2053, converting it into the movement of the linkage 301 itself and the fixed movable seat 303. The elastic reset member 308 is connected between the movable seat 303 and the fixed point of the adjustment section 1, providing a reset preload force opposite to the direction of travel for the entire washing section 3, thereby realizing the reciprocating movement of the movable seat 303. Inside the movable seat 303, the elastic pressure member 305 continuously pushes the mounting plate 304 and the cleaning plate 309 fixed thereon toward the cabinet wall, ensuring that the bristles are always in close contact with the surface. The connecting steel cable 306, which is set between the two movable seats 303, passes around the connecting wheel 307 on the adjustment part 1, forming a flexible connection synchronization mechanism to ensure that the two movable seats 303 move synchronously during walking and vibration.

[0027] Please see Figure 5 , Figure 7 , Figure 8 and Figure 10 As shown, a horizontal limiting groove is provided inside the linkage 301. The inside of the limiting groove is slidably connected to the outer edge of the connecting cylinder 2051, and the length of the limiting groove is the same as the eccentric distance of the eccentric wheel 2053. When the eccentric wheel 2053 rotates with the connecting cylinder 2051, its eccentric mass or protruding portion pushes against the linkage 301. However, due to the constraint of the limiting groove, the linkage 301 can only slide along the horizontal direction of the limiting groove.

[0028] Please see Figure 5 , Figure 7 and Figure 8 As shown, the cleaning plate 309 and the movable seat 303 are fixed by magnetic attraction, and a cleaning brush is fixedly installed on the outer side of the cleaning plate 309. The magnetic fixing method allows operators to instantly attach or easily detach the cleaning plate 309 and the movable seat 303 by hand without using any tools, simplifying the brush head replacement process and enabling convenient operation of the equipment in terms of preparation and maintenance.

[0029] Please see Figure 3 , Figure 5 and Figure 6 As shown, the adjustment unit 1 includes a mounting base 101, a horizontal moving base 102, a vertical moving base 103, a follower base 104, an elastic pressing member 105, a water storage tank 106, a delivery pump 107, and a scraper 108. A drive motor 201 is fixedly connected to the inner side of the mounting base 101. One side of the horizontal moving base 102 is slidably connected to one side of the mounting base 101. The lower end of the vertical moving base 103 is slidably connected to the upper end of the mounting base 101. One side of the follower base 104 is slidably connected to the vertical moving base 103, and the lower end of the follower base 104 is slidably connected to the horizontal moving base 102. Two elastic pressing members 105 are provided, one of which is... A flexible extrusion member 105 is disposed between the mounting base 101 and the vertical moving base 103, and between the horizontal moving base 102 and the follower base 104. The water storage tank 106 is fixedly connected to the interior of the mounting base 101, and the delivery pump 107 is fixedly connected to the interior of the mounting base 101. The input end of the delivery pump 107 is connected to the interior of the water storage tank 106. The mounting base 101, the horizontal moving base 102, the vertical moving base 103, and the follower base 104 are provided with spray pipes, which are connected to the output end of the delivery pump 107. The scraper 108 is assembled at the mounting base 101, the horizontal moving base 102, the vertical moving base 103, and the follower base 104. Place the device into the freezer. The operator first pulls or pushes the horizontal moving seat 102 horizontally, allowing it to slide along one side of the mounting base 101 to adjust the width of the device; then, they pull or push the vertical moving seat 103 vertically, allowing it to slide along the upper end of the mounting base 101 to adjust the height of the device. The follower seat 104, through its double sliding connection with both the vertical moving seat 103 and the horizontal moving seat 102, automatically completes position linkage, ensuring that the entire adjustment frame always maintains a complete rectangular structure, closely conforming to the contours of the freezer's interior space. Two elastic pressing elements 105, like springs, apply continuous, outward elastic force to the vertical moving seat 103 and the horizontal moving seat 102 respectively. This force stably presses the entire frame of the adjustment unit 1 against the inner wall of the freezer, achieving self-adaptive fixation without external tools and providing basic pressure for subsequent scraping and cleaning. When the cleaning program is started, the delivery pump 107 fixed in the mounting base 101 starts to work. The delivery pump 107 draws detoxifying or cleaning liquid from the water storage tank 106 and sprays it evenly onto the inner wall of the cabinet from multiple positions and angles through the spray pipe network embedded in the mounting base 101, the horizontal moving base 102, the vertical moving base 103 and the follower base 104, so as to achieve preliminary wetting, disinfection and softening of stubborn stains on all surfaces inside the cabinet. The edge of the scraper 108 remains in contact with the cabinet wall. When the device moves as a whole due to the movement of the drive unit 2, the scraper 108 can pre-scrape the stains attached to the inner wall for preliminary cleaning. Through the sliding mechanism formed by the mounting base 101, the horizontal moving base 102, the vertical moving base 103, and the follower base 104, and the self-adjusting pressure provided by the elastic pressing member 105, the adjustment unit 1 can quickly adapt to the internal space of freezers of different lengths, widths, and heights, solving the problem of poor versatility of special equipment and enabling it to be used for various types of freezers.

[0030] Please see Figure 6 As shown, a limiting device is provided between the mounting base 101 and the horizontal moving base 102, and between the vertical moving base 103 and the follower base 104. The limiting device includes a positioning block 1011, a sliding block 1012, a limiting block 1013, and an elastic fixing member 1014. The positioning block 1011 is fixedly connected to the corresponding mounting base 101 and the horizontal moving base 102. The interior of the sliding block 1012 is slidably connected to the positioning block 1011. The sliding block 1012 is fixedly connected to the corresponding vertical moving base 103 and the follower base 104. The limiting block 1013 is slidably connected inside the sliding block 1012, and one end of the limiting block 1013 is in slidable contact with the interior of the positioning block 1011. The elastic fixing member 1014 is disposed between the limiting block 1013 and the sliding block 1012. Please see Figure 9As shown, one end of the limiting block 1013 is set to be arc-shaped, and the interior of the positioning block 1011 is provided with multiple equidistant positioning grooves that cooperate with one end of the limiting block 1013. When the operator pulls the vertical moving seat 103 or the horizontal moving seat 102 to adjust the size of the device, the sliding block 1012 fixed to them begins to slide along the positioning block 1011 fixed on the mounting seat 101 or the horizontal moving seat 102. The limiting block 1013 located inside the sliding block 1012 is pushed and compressed by the elastic fixing member 1014 under the action of the contact friction between the limiting block 1013 and the surface of the positioning block 1011, thereby retracting into the sliding block 1012. When adjusted to a preset size corresponding to a positioning groove on the positioning block 1011, the arc-shaped end of the limiting block 1013 slides into the corresponding positioning groove on the positioning block 1011 under the continuous thrust of the elastic fixing member 1014.

[0031] At this point, a clear clicking sound and a tactile feedback will be heard, indicating that the device has automatically locked. The limit block 1013 has engaged in the groove, mechanically preventing the sliding block 1012 from moving further relative to the positioning block 1011, thus firmly fixing the adjusting part 1 at this size. When readjustment is required, the operator should apply a pulling or pushing force that is slightly greater than the pressure and friction of the elastic fastener 1014, so that the sliding block 1012 tends to move, forcing the inclined or arc surface of the limiting block 1013 to act with the edge of the positioning groove, squeezing it out of the groove and recompressing the spring, so that the device returns to the sliding state and the next size adjustment can be performed. This allows operators to set and lock dimensions by feel alone, without needing any tools, greatly improving the speed of equipment adjustment and ease of operation.

[0032] The working principle of this invention is as follows: after the device is placed in freezers of different sizes, the operator can manually adjust the frame size of the adjustment part 1 so that its outline basically matches the inner wall space of the freezer. When the drive motor 201 is powered on and starts to rotate, the drive rod 202 fixed to the output end of the drive motor 201 rotates synchronously. The rotation of the drive rod 202 drives the connecting rod 203, which is slidably connected to the outer edge, to rotate. The end of the connecting rod 203 meshes with the middle of the linkage rod 204 through a bevel gear. The rotation of the connecting rod 203 drives the linkage rod 204 to rotate together, thereby changing the power transmission direction of the drive motor 201 by 90 degrees. This causes the linkage rod 204 to start rotating around its own axis. The rotation of the linkage rod 204 transmits power to the drive shaft 205, which in turn transmits power to the washing unit 3. The washing unit 3 begins to move relative to the frame of the adjusting unit 1 and uses its cleaning components to apply pressure to the inner surface of the freezer and perform repeated friction cleaning.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
