Description

Technical Field

[0001] This utility model relates to the field of medical cleaning tools, and in particular to an improved bed cleaning brush. Background Technology

[0002] Medical bed brushes consist of a brush cover and a brush. The brush cover and brush are separate and are usually fixed by a frame on top of the brush. The brush covers are stacked together. There is a layer of disinfectant on the outside of the brush cover, and the surface of the brush cover is not smooth, which can absorb some dirt from the bed.

[0003] For example, patent document CN217185179U discloses a medical bed brush with automatic membrane replacement, including a sponge brush body and a handle set at the upper end of the sponge brush body. A rewind box is set between the sponge brush body and the handle. An unwind roller is set inside the rewind box, and a bed brush membrane to be used is placed on the unwind roller. A clamping component is set on one side of the rewind box. The clamping component includes a serrated block. The bed brush membrane passes through the rewind box, goes around the sponge brush body, and is clamped by the serrated block. The serrated block is also used to cut off the used bed brush membrane. The purpose of this design is to ensure that the medical bed brush can automatically replace the membrane, reduce the frequency of membrane replacement by nursing staff and hand contact, and avoid cross-infection. The above-mentioned device provides a technical solution for automatically changing the membrane of a medical bed brush. However, it lacks an effective fixing method, which can easily lead to the loosening of the bed brush membrane during use. In the prior art, the brush sleeve is fixed by clamping. Since medical staff are busy with morning cleaning work, simply combining the two methods will cause inconvenience to medical staff and reduce work efficiency. Therefore, a bed brush that can be convenient for both membrane changing and fixing and is easy to operate is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an improved bed brush to solve the above-mentioned problems.

[0006] An improved bed brush includes a brush body, which includes a brush sleeve box. A support frame is fixedly connected to the bottom of the brush sleeve box, and a brush body is fixedly connected to the bottom of the support frame. A brush sleeve roll is disposed inside the brush sleeve box, and a brush sleeve film is wound on the brush sleeve roll. The brush sleeve film extends from one side of the brush sleeve box and covers the brush body. A fixing mechanism is provided on the support frame, which includes two symmetrically arranged rotating arms rotatably connected to the support frame. A clamp is fixedly connected to the other end of each rotating arm. A film changing mechanism is provided on one side of the brush sleeve box, which includes a film take-up roller. The brush sleeve box is able to contact the brush sleeve film. A linkage mechanism is provided on the other side of the brush sleeve box. The linkage mechanism includes a rack that is slidably connected to the brush sleeve box. A guide rod is fixedly connected to one side of the rack. The guide rod is shaped like two parallel lines, one inside and one outside, connected by a smooth curve. A sliding ring is slidably connected to the guide rod.

A drive gear is rotatably connected to one side of the front end of the brush sleeve box. A transmission assembly is provided at the front end of the brush sleeve box. The transmission assembly is used to drive the gear to drive the film take-up roller to rotate.

[0007] Preferably, a handle is fixedly connected to the top of the brush sleeve box, and two symmetrically arranged through slots are opened on the support frame. The brush sleeve film passes through one through slot of the support frame and is transmitted out from the other through slot. A fixed shaft is fixedly connected inside the brush sleeve box, and a brush sleeve roll is installed on the fixed shaft. A film outlet is opened at the bottom of one side of the brush sleeve box, and the brush sleeve film passes out of the brush sleeve box from the film outlet. A layer of sponge covers the brush body.

[0008] Preferably, the fixing mechanism further includes clamping rods symmetrically arranged on both sides of the brush body, the clamping rods being configured to smoothly contract from the outside in and then smoothly expand outwards, and the clamping sleeve being configured as an elastic tube sleeve with a notch.

[0009] Preferably, a connecting frame is fixedly connected to the front end of the support frame, and two symmetrically arranged transmission rods are rotatably connected to both ends of the connecting frame. One end of the transmission rod is fixedly connected to the rotating arm, and the other end of the transmission rod is fixedly connected to a first gear. The two first gears are driven by an even number of second gears, and the second gears are rotatably connected to the connecting frame.

[0010] Preferably, the transmission assembly includes a combined gear rotatably connected to the front end of the brush sleeve box.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-9As shown, an improved bed brush includes a brush body, which includes a brush sleeve box 101. A support frame 104 is welded to the bottom of the brush sleeve box 101, and a brush body 103 is welded to the bottom of the support frame 104. A brush sleeve roll 107 is disposed inside the brush sleeve box 101, and a brush sleeve film 108 is wound on the brush sleeve roll 107. The brush sleeve film 108 extends from one side of the brush sleeve box 101 and covers the brush body 103. A fixing mechanism is provided on the support frame 104, which includes two symmetrically arranged rotating arms 201 rotatably connected to the support frame 104. A clamp 202 is fixedly connected to the other end of each rotating arm 201. A film changing mechanism is provided on one side of the brush sleeve box 101. The film changing mechanism includes a film taking-up roller 405, which can contact the brush sleeve film 108. A linkage mechanism is provided on the other side of the brush sleeve box 101. The linkage mechanism includes a rack 301 that is slidably connected to the brush sleeve box 101. The rack 301 has no teeth within a certain range at its front end. A guide rod 302 is fixedly connected to one side of the rack 301. The guide rod 302 is shaped like two parallel lines, one inside and one outside, connected by a smooth curve. A sliding ring 303 is slidably connected to the guide rod 302. A telescopic block 304 is fixedly connected to the top of the rotating arm 201 on one side. The other end of the telescopic block 304... Fixedly connected to the sliding ring 303, a drive gear 305 is rotatably connected to one side of the front end of the brush sleeve box 101. A transmission assembly is provided at the front end of the brush sleeve box 101. The transmission assembly is used to drive the gear 305 to drive the film take-up roller 405 to rotate. When it is necessary to replace the brush sleeve film 108 on the brush body 103, the medical staff pushes the rack 301 to move. The rack 301 drives the guide rod 302 to move. The guide rod 302 moves forward and drives the sliding ring 303 to move inward. The sliding ring 303 drives the telescopic block 304 to retract. The telescopic block 304 drives the rotating arm 201 to rotate. The rotating arm 201 drives the clamp 202 to move and make it... Disengaging from clamping rod 203, the brush sleeve film 108 can move freely. At this time, the teeth on rack 301 begin to mesh with drive gear 305. Rack 301 drives drive gear 305 on brush sleeve box 101 to rotate. Drive gear 305 drives take-up roller 405 to rotate through transmission assembly. Take-up roller 405 moves brush sleeve film 108 through friction generated by squeezing, replacing the used brush sleeve film 108. Then rack 301 resets, and rack 301 drives guide rod 302 to reset. Guide rod 302 drives clamping sleeve 202 to re-engage with clamping rod 203 to fix brush sleeve film 108.

[0030] A handle 102 is fixedly connected to the top of the brush holder 101. Two symmetrically arranged through slots are opened on the support frame 104. The brush sleeve 108 passes through one through slot of the support frame 104 and exits from the other through slot. This can avoid interference between the brush sleeve 108 and the rotating arm 201. A fixed shaft 105 is fixedly connected inside the brush holder 101. A brush sleeve roll 107 is installed on the fixed shaft 105. A film outlet 106 is opened at the bottom of one side of the brush holder 101. The brush sleeve 108 passes through the film outlet 106 and exits the brush holder 101. The brush body 103 is covered with a layer of sponge. The sponge can absorb disinfectant, thereby achieving disinfection of the bed surface during the cleaning process. The staff can hold the handle 102 and clean the hair and debris on the patient's bed by sweeping.

[0031] The fixing mechanism also includes clamping rods 203 symmetrically arranged on both sides of the brush body 103. The clamping rods 203 are designed to smoothly contract from the outside in and then smoothly expand outward. The sleeve 202 is an elastic tube sleeve with a notch, and the included angle of the notch of the sleeve 202 is an acute angle. This design of the sleeve 202 and the clamping rods 203 can effectively improve the fixing effect, thereby preventing the brush sleeve film 108 from moving during the sweeping process. A connecting frame 204 is fixedly connected to the front end of the support frame 104. Two symmetrically arranged transmission rods 207 are rotatably connected to both ends of the connecting frame 204. One end of the transmission rod 207 is fixedly connected to the rotating arm 201, and the other end of the transmission rod 207 is fixedly connected to... The first gear 205 is connected to the second gear 206 via two second gears 206. The second gear 206 is rotatably connected to the connecting frame 204. One side rotating arm 201 rotates, causing the clamp 202 to disengage from the clamping rod 203. At the same time, the rotating arm 201 drives the transmission rod 207 on one side to rotate, which in turn drives the first gear 205 on one side to rotate. The first gear 205 drives another first gear 205 to rotate via the two second gears 206. The other first gear 205 drives another rotating arm 201 to rotate via another transmission rod 207. In this way, the clamps 202 and clamping rods 203 on both sides can be disengaged simultaneously.

[0032] The transmission assembly includes a combined gear 307 rotatably connected to the front end of the brush sleeve box 101. The rear gear of the combined gear 307 is a bevel gear, and the two are connected by a ratchet and pawl. The combined gear 307 can only transmit power in one direction. A driving bevel gear 306 is meshed on one side of the front end of the combined gear 307. The driving bevel gear 306 is fixedly connected to the drive gear 305. A driven gear 308 is meshed on the rear side of the combined gear 307. The driven gear 308 is fixedly connected to the take-up roller 405. When the drive gear 305 rotates, it drives the driving bevel gear 306 to rotate. The driving bevel gear 306 drives the combined gear 307 to rotate. At this time, the ratchet and pawl can transmit power. The combined gear 307 drives the driven gear 308 to rotate. The driven gear 308 drives the take-up roller 405 to rotate. This enables the brush sleeve film 108 to be moved and replaced. When the rack 301 is reset, the driving bevel gear 306 reverses, but the ratchet and pawl cannot transmit power, so the take-up roller 405 will not rotate.

[0033] The membrane changing mechanism also includes a fixed bracket 401 fixedly connected to the brush sleeve box 101. A sliding frame 402 is slidably connected to the fixed bracket 401. The sliding frame 402 can drive the take-up roller 405 to move, thereby controlling whether it contacts the brush sleeve film 108. The sliding frame 402 is rotatably connected to the take-up roller 405. The outer layer of the take-up roller 405 is covered with rubber to increase the friction between the take-up roller 405 and the brush sleeve film 108 and prevent relative sliding. A saw blade 403 is fixedly connected to the top of the sliding frame 402. Medical staff can quickly tear off the brush sleeve film 108 by using the saw blade 403 to avoid cross-infection. Several evenly arranged springs 404 are fixedly connected between the sliding frame 402 and the fixed bracket 401. The springs 404 provide pressure to the take-up roller 405 and drive the sliding frame 402 to reset.

[0034] Working principle: When it is necessary to replace the brush sleeve film 108 on the brush body 103, the medical staff pushes the rack 301 to move. The rack 301 drives the guide rod 302 to move. The guide rod 302 moves forward, driving the sliding ring 303 to move inward. The sliding ring 303 drives the telescopic block 304 to retract. The telescopic block 304 drives the rotating arm 201 to rotate. The rotating arm 201 drives the clamp 202 to move and disengage it from the clamp rod 203. In this way, the brush sleeve film 108 can move freely. At this time, the teeth on the rack 301 begin to mesh with the drive gear 305. The rack 301 drives the drive gear 305 on the brush sleeve box 101 to rotate. The drive gear 305 drives the active bevel gear 3... When the gear 306 rotates, the driving bevel gear 306 drives the combined gear 307 to rotate. At this time, the ratchet and pawl can transmit power. The combined gear 307 drives the driven gear 308 to rotate. The driven gear 308 drives the take-up roller 405 to rotate. The take-up roller 405 drives the brush sleeve film 108 to move through the friction generated by the extrusion, replacing the used brush sleeve film 108. Then the rack 301 resets. The rack 301 drives the guide rod 302 to reset. The guide rod 302 drives the clamp 202 to re-engage with the clamp rod 203 to fix the brush sleeve film 108. When the rack 301 resets, the driving bevel gear 306 reverses, but the ratchet and pawl cannot transmit power, so the take-up roller 405 will not rotate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
