Description

Technical Field

[0001] The invention relates to a cleaning and disinfecting device, in particular to a cleaning and disinfecting device capable of preventing disinfectant liquid from volatilizing and evaporating. Background Art

[0002] As people pay more and more attention to health and their awareness of disease and bacteria prevention continues to improve, the external public environment outside the home is becoming increasingly complex, and the risk of various pathogens and viruses is increasing. For example, public toilets (especially toilets used by patients such as hospital toilets), hospitals, meat, vegetable and animal markets, epidemic areas, places contaminated by pathogens and viruses, etc. People cannot avoid entering these places due to work, life, and study. The chance and possibility of their soles coming into contact with and being contaminated by these pathogens and viruses (such as highly infectious bacteria, viruses, hepatitis viruses, HIV, tuberculosis viruses, syphilis, avian influenza, African swine fever, Sabae viruses, parasites, dirt, etc.) cannot be ruled out. Therefore, the risk of people inadvertently bringing harmful substances such as pathogens, viruses, parasites, etc. back home through the soles of their shoes is extremely high.

[0003] In addition, various biopharmaceutical factories, breeding farms, scientific research sites, epidemic areas and other places require isolation from the invasion of various foreign bacteria, viruses and microorganisms for health and safety reasons.

[0004] The invention patent with application publication number CN 108434494 A discloses a disinfection device with automatic sealing function, including a disinfection pool, a cleaning brush plate and a control mechanism, wherein the brush plate is provided with a plurality of liquid guiding and sand settling holes, a closing body and a spring, the closing body is located in the liquid guiding and sand settling holes, one end of the spring is connected to the closing body, and the other end of the spring is connected to the brush plate. When in use, when a person enters the disinfection pool 1, he steps on the brush plate, and a movement difference is generated between the bottom plate 8 and the closing body 10. The bottom plate 8 sinks first, and enters the upper surface of the bottom plate 8 along the gap between the liquid guiding and sand settling holes 9 and the closing body 10, thereby disinfecting the soles of the person's shoes. When the person leaves the disinfection pool 1, the closing body 10 drives the bottom plate 8 to float, and the disinfectant liquid on the bottom plate 8 flows back to the disinfection pool 1 along the gap between the closing body 10 and the liquid guiding and sand settling holes 9. The components in the brush plate 6 cooperate with the inner surrounding side plates 16 to close the disinfection pool 1, thereby saving disinfectant liquid.

[0005] In actual use, since the disinfectant liquid is volatile and has an odor, and the disinfection tank in the above-mentioned disinfection device is always open, that is, the disinfectant liquid is in a state of evaporating outward at any time, which will not only accelerate the consumption of the disinfectant liquid, but also make the surrounding environment full of odor, which has a bad impact. Summary of the invention

[0006] The object of the present invention is to overcome the above-mentioned problems and provide a cleaning and disinfecting device that can prevent the disinfectant liquid from volatilizing and evaporating. The cleaning and disinfecting device can isolate the disinfectant liquid from the outside world when not in operation, thereby reducing the volatilization of the disinfectant liquid and preventing its odor from spreading everywhere.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A cleaning and disinfecting device for preventing disinfectant liquid from volatilizing and evaporating comprises a cleaning and disinfecting container for containing the disinfectant liquid, a cleaning and disinfecting pedal arranged in the cleaning and disinfecting container, a cover plate arranged at the opening of the cleaning and disinfecting container for physically sealing the disinfectant liquid, and a cover plate driving mechanism for driving the cover plate to open or close.

[0009] The working principle of the above cleaning and disinfection device for preventing volatilization and evaporation of disinfection liquid is:

[0010] When the soles need to be disinfected and cleaned, the user can first step on the driving pedal, so that the cover driving mechanism drives the cover to flip upward around the hinge shaft until it is fully opened, and then the user places the soles in the cleaning and disinfection container, and steps on the cleaning and disinfection pedal, so that the cleaning and disinfection pedal is immersed in the disinfection liquid. At this time, the cleaning and disinfection pedal and the disinfection liquid respectively clean and disinfect the soles. When the disinfection is completed, the user walks out of the cleaning and disinfection container, and then closes the pedal and covers the cleaning and disinfection container to avoid waste caused by the volatilization of the disinfection liquid, and also avoids the impact of the volatilized gas on the surrounding environment.

[0011] In a preferred embodiment of the present invention, the cover plate driving mechanism includes a driving pedal and an intermediate transmission mechanism, the intermediate transmission mechanism includes a rotating shaft and a transmission assembly for transmitting the power of the driving pedal to the rotating shaft, the rotating shaft is fixedly connected to one end of the cover plate through a fixing structure, and is connected to the side wall of the cleaning and disinfection container through a hinged connection structure;

[0012] The transmission assembly includes a rack and a rotating gear that mesh with each other. The rotating gear is fixedly arranged on the rotating shaft and is located between the cleaning and disinfection container and the driving pedal; the rack is vertically arranged on the driving pedal and faces the rack. With the above structure, when the driving pedal is stepped on downward, the rack moves downward, thereby driving the rotating gear to rotate. Since the rotating gear is located between the cleaning and disinfection container and the driving pedal, as the rack moves downward, the rotating gear rotates in the direction of opening the cover, thereby driving the cover to open upward around the rotating shaft. In this preferred embodiment, by using gears and racks for transmission and setting a reasonable transmission ratio, there is enough travel to drive the cover to open to a desired angle without the need for other auxiliary driving mechanisms.

[0013] The transmission assembly is a gear transmission mechanism, in which a driven gear is fixedly arranged on a rotating shaft, and a driving gear in the gear transmission mechanism is fixedly connected to a driving pedal, and the driving pedal is rotatably connected to a side wall of the cleaning and disinfection container. In a non-pedaled state, the driving pedal is lower than the top surface of the cover plate in a closed state.

[0014] Preferably, a pedal fixing seat is provided below the driving pedal, and a limiting guide hole is provided on the pedal fixing seat extending vertically; the top of the driving pedal is a pedal portion, and a pedal spring is provided between the pedal portion and the upper surface of the pedal fixing seat;

[0015] The rotating gear is fixed on the rotating shaft through a one-way bearing, and the locking direction of the one-way bearing is the opening direction of the cover. Through the above structure, when the driving pedal is released, the driving pedal is reset upward under the action of the pedal spring to prepare for the next use; wherein, since the rack is arranged on the driving pedal and the rack is meshed with the rotating gear, generally, when the rack moves, the rotating gear will also rotate; for this reason, the one-way bearing is used as the intermediate connecting piece connecting the rotating gear and the rotating shaft in the present embodiment, and its locking direction is the opening direction of the cover, so that when the driving pedal moves downward, the driving direction of the rack is the locking direction of the one-way bearing, thereby driving the rotating shaft to rotate; when the driving pedal moves upward and resets, the driving direction of the rack is the free rotation direction of the one-way bearing, so the rotating gear only rotates around the rotating shaft idly, and cannot form an effective drive, thereby not driving the cover to close.

[0016] In a preferred embodiment of the present invention, the cover driving mechanism further comprises a closer for driving the cover to close autonomously, the closer being arranged at one end of the rotating shaft, and its extending direction being perpendicular to the extending direction of the rotating shaft;

[0017] The closer comprises a housing, a transmission shaft, an energy storage spring and a damping member. The transmission shaft is provided with a spring driving cam for driving the energy storage spring to compress and store energy and a damping driving cam for compressing the damping member. The transmission shaft is concentric with the rotating shaft and is fixedly connected to the rotating shaft. When the rotating shaft rotates in the direction of opening the cover, the spring driving cam rotates with the transmission shaft and compresses the energy storage spring, and the damping driving cam moves away from the compression damping member, and the compression damping member extends. When the rotating shaft rotates in the direction of closing the cover, the spring driving cam moves away from the energy storage spring, and the energy storage spring releases potential energy to recover, driving the transmission shaft to rotate in the direction of closing the cover, driving the cover to close, and at the same time, the damping driving cam compresses the damping member with the transmission shaft, and the damping member resists the potential energy of the energy storage spring through its own damping structure, so that the cover is slowly closed.

[0018] In a preferred embodiment of the present invention, the rotation axis is located on the right side of the cleaning and disinfecting container along the direction of entering the cleaning and disinfecting container, and when the cover is opened, it rotates around the rotation axis toward the right side of the cleaning and disinfecting container.

[0019] In a preferred embodiment of the present invention, the cover driving mechanism includes an opening mechanism for causing the cover to open and a closing mechanism for causing the cover to close, the opening mechanism includes an opening pedal and an opening power transmission mechanism, when the opening pedal is pressed, the opening power transmission mechanism drives the cover to flip upward around the hinge shaft; the closing mechanism includes a closing pedal and a closing power transmission mechanism, when the closing pedal is pressed, the closing power transmission mechanism drives the cover to flip downward around the hinge shaft;

[0020] The opening power transmission mechanism includes a lifting plate, a transverse driving structure for driving the lifting plate to move transversely parallel to the flipping plane of the cover plate, and a lifting structure that completes the lifting work with the transverse movement of the lifting plate; the lifting plate is transversely arranged on one side of the cleaning and disinfection container, and its extension direction is parallel to the flipping plane of the cover plate; the lifting structure includes a lifting slope and a lifting boss, the lifting slope is arranged on the lifting plate, and the inclined direction is opposite to the driving direction of the transverse driving structure; the lifting boss is arranged on the cover plate, located at the edge of the cover plate close to the lifting plate, and extends downward. When the transverse driving mechanism drives the lifting plate to move transversely, the lifting slope approaches and squeezes on the lifting boss, and as the transverse movement continues, the lifting boss presses the lifting slope to move upward, that is, the lifting slope lifts the lifting boss upward, so that the cover plate flips upward around the hinge axis.

[0021] Preferably, the transverse driving structure includes a transverse driving rod and a transverse driving groove; the transverse driving rod is arranged on the opening pedal, and the transverse driving groove is arranged on the end of the lifting plate close to the opening pedal, and its opening faces upward; a transverse driving inclined surface is arranged at the opening. Generally, when the opening pedal is stepped down, the transverse driving rod moves downward and is pressed on the transverse driving inclined surface, so as the transverse driving rod moves downward, the lifting plate moves laterally in the direction of the transverse driving inclined surface, and then the cover plate is lifted by the lifting structure.

[0022] Preferably, the transverse drive structure includes a transverse drive motor, a transverse transmission assembly and a first time relay, the transverse transmission assembly is connected to the lifting plate, and the switch of the first time relay is located directly below the opening pedal; the first time relay and the transverse drive motor form an electrical connection. During operation, the opening pedal touches the switch of the first time relay downward, starts the first time relay, and closes the circuit, so that the transverse drive motor starts to work and drives the lifting plate to move laterally; at the same time, the first time relay starts timing, and disconnects the circuit after a certain period of time (the time corresponds to the distance of the lateral movement), so that the transverse drive motor stops working, and the lifting structure has lifted the lifting plate.

[0023] Preferably, the opening power transmission mechanism further includes a hydraulic support rod for assisting the cover to be fully opened or fully closed, one end of the hydraulic support rod is hinged on the edge of the cleaning and disinfection container, and the other end is hinged on the cover. Since the lifting stroke of the lifting structure is limited, the cover cannot be fully opened. Therefore, after the lifting structure lifts the cover, the hydraulic support rod then drives the cover upward to continue to flip upward until it is fully opened.

[0024] A preferred embodiment of the present invention is that a first fixing seat is provided below the opening pedal, and a first return spring for driving the opening pedal to return to its original position is provided on the first fixing seat; and a second return spring is provided between the lifting plate and the first fixing seat.

[0025] In a preferred embodiment of the present invention, the closing power transmission mechanism comprises a rotary pressing arm for driving the cover plate to flip downward by rotary pressing, and a rotary driving mechanism for driving the rotary pressing arm to rotate;

[0026] Among them, the rotating pressing arm is located on the outer side of the hinge between the cover plate and the cleaning and disinfection container, the upper end is the pressing end, and the lower end is hinged on the mounting frame, and the mounting frame is fixedly set on the edge of the cleaning and disinfection container; the rotating drive mechanism includes a second fixed seat, an intermediate push rod and the closing pedal, the second fixed seat is fixedly set on the edge of the cleaning and disinfection container, and a vertically extending guide groove is provided therein; the lower end of the closing pedal is a guide part, and extends into the guide groove; one end of the intermediate push rod is fixedly connected to the closing pedal, and the other end extends to one side of the rotating pressing arm; the rotating pressing arm is inclined toward the direction of the cover plate, and the vertical projection of the intermediate push rod coincides with the rotating pressing arm. The principle of closing the cover mentioned above is: stepping on the closing pedal downward causes the closing pedal to move downward along the second fixed seat. Since the intermediate push rod is fixedly connected to the closing pedal, when the closing pedal moves downward, the intermediate push rod is squeezed on the rotating pressing arm, thereby driving it to move in the direction of the cover. At this time, the hydraulic support rod is in a non-working state, and the thrust of the rotating pressing arm is greater than the resistance of the hydraulic support rod itself, thereby causing the pressing end to push the cover, and then close the cover; since the pushing stroke of the rotating pressing arm is limited, the cover cannot be completely closed. Therefore, when the rotating pressing arm stops driving, the angle between the cover and the cleaning and disinfection container is less than 90°, and the cover will continue to rotate downward under the action of its own gravity, thereby completely closing the cover.

[0027] Preferably, the rotary drive mechanism includes a second fixed seat, an intermediate push rod, an intermediate push block and the closing pedal, wherein the second fixed seat is fixedly arranged on the edge of the cleaning and disinfection container, and a vertically extending guide groove is provided therein; the lower end of the closing pedal is a guide portion, and extends into the guide groove; the intermediate push block is located on the side of the rotary pressing arm away from the cover plate, and the lower end is hinged on the mounting frame; one end of the intermediate push rod is fixedly connected to the closing pedal, and the other end is connected to the upper end of the intermediate push block; the pressing end of the rotary pressing arm extends toward the cover plate. Through the above structure, when the closing pedal is stepped down, the intermediate push rod drives the intermediate push block to rotate, thereby pushing the rotary pressing arm to rotate toward the cover plate, thereby causing the cover plate to close.

[0028] In a preferred embodiment of the present invention, a third return spring is provided between the mounting bracket and the rotating pressing arm, and a fourth return spring is provided between the mounting bracket and the intermediate push block.

[0029] A preferred solution of the present invention is that the cover plate is two leaves, and the two cover plates form a split structure, the two lifting slopes are two, and the two lifting slopes are respectively arranged corresponding to the lifting bosses on the two cover plates, and the two rotating pressing arms and the middle push blocks are two, and the two rotating pressing arms and the middle push blocks are respectively arranged on the outside of the hinges between the two cover plates and the cleaning and disinfection container. When working, the lateral drive mechanism drives the lifting plate to move horizontally, so that the two lifting slopes are respectively in contact with the lifting bosses on the two cover plates, and the two cover plates are opened by applying a lifting force to the two lifting bosses; the two cover plates are closed by driving the two rotating pressing arms to perform a pressing movement.

[0030] A preferred solution of the present invention, wherein the opening power transmission mechanism includes a flip drive motor and a second time relay, the flip drive motor is connected to the cover plate through a gear transmission assembly, the gear transmission assembly includes a driving gear and a driven gear, the driving gear is fixed on the output shaft of the flip drive motor, and the driven gear is fixed on the cover plate; the rotation center of the driven gear is the same as the rotation center of the cover plate; the switch of the second time relay is located below the opening pedal, and the flip drive motor is electrically connected to the second time relay. During operation, the opening pedal touches the switch of the second time relay downward, starts the second time relay, and closes the circuit, so that the flip drive motor starts to work and flips the cover plate; at the same time, the second time relay starts timing, and disconnects the circuit after a certain period of time (the time corresponds to the flip angle), so that the flip drive motor stops working, and is in a fully open state at this time.

[0031] A preferred solution of the present invention, wherein the closing power transmission mechanism includes the flip drive motor and the third time relay, the switch of the third time relay is located directly below the closing pedal; the flip drive motor is electrically connected to two third time relays, and the two third time relays are respectively located on circuits connected in parallel with each other. Similarly, when the closing pedal is stepped on, the third time relay is started, the corresponding circuit is closed, and the flip drive motor is reversed, thereby driving the cover to rotate in the closing direction; at the same time, the third time relay starts timing, and the circuit is disconnected after a certain period of time (the time corresponds to the flip angle), so that the flip drive motor stops working, and is in a closed state at this time.

[0032] A preferred embodiment of the present invention is that a supporting portion for supporting a cleaning and disinfecting pedal is provided in the cleaning and disinfecting container; the cleaning and disinfecting pedal includes a brush plate, a bristle bundle arranged on the brush plate for brushing the soles of shoes, and a liquid guiding and sand settling hole for disinfectant liquid and mud and sand to enter and exit the brush plate, wherein the bristle bundle is a plurality of bundles, and the plurality of bristle bundles are arranged on the upper side of the brush plate, and the plurality of liquid guiding and sand settling holes are distributed in the gaps between the bristle bundles on the brush plate; in the stepped state, the brush plate is supported on the supporting portion, and the liquid level of the disinfectant liquid reaches the bristle bundles on the upper side of the brush plate.

[0033] In a preferred embodiment of the present invention, the brush plate is a lifting brush plate; in a non-trampling state, there is a movement space between the support portion and the bottom of the cleaning and disinfection pedal for the brush plate to move up and down; in a trampling state, the brush plate moves downward until it is supported on the support portion, and the liquid level of the disinfectant reaches the hair bundle on the upper side of the brush plate. The purpose of this arrangement is that, in a non-trampling state, the cleaning brush floats on the liquid level of the disinfectant liquid under the action of buoyancy, or is located at or above the liquid level under the support of the elastic element, thereby covering the disinfectant liquid to prevent the disinfectant liquid from volatilizing.

[0034] In a preferred embodiment of the present invention, a one-way rotation mechanism is provided between the cleaning and disinfecting pedal and the rotating shaft, and the one-way rotation mechanism is a ratchet mechanism, including a ratchet and a pawl;

[0035] The ratchet is fixedly arranged on the rotating shaft, and its tooth direction is the same as the opening direction of the cover; the pawl is arranged above the ratchet and is connected to the cleaning and disinfection pedal in the cleaning and disinfection container through an intermediate connecting rod, one end of the intermediate connecting rod is hinged to the ratchet, and the other end passes through the cleaning and disinfection container and extends under the cleaning and disinfection pedal; a torsion spring is provided between the ratchet and the intermediate connecting rod for urging the ratchet to be in a fixed posture; when the cleaning and disinfection pedal is in a non-stepped state, the ratchet is outside the rotation range of the ratchet; when the cleaning and disinfection pedal is in a stepped state, the ratchet enters the rotation range of the ratchet.

[0036] Generally, when the cover is opened, the cover will automatically close under the action of the closer. In order to prevent the cover from closing during the cleaning and disinfection process, the inventor proposes this preferred solution. In this preferred solution, when the cleaning and disinfection pedal is stepped on, the middle connecting rod located below will be driven to move downward, so that the other end of the middle connecting rod is the pawl that enters the rotation range of the ratchet. Since the tooth direction of the ratchet is the same as the opening direction of the cover, that is, the direction of closing the cover is the direction in which the pawl locks the ratchet, the pawl is directly stuck between the ratchet teeth of the ratchet to lock the ratchet, so that the rotating shaft stops rotating and the cover stops closing, so as to continue cleaning and disinfection; in addition, when the automatic closing angle of the cover is too large and affects the cleaning and disinfection, the user can push the cover by hand or step on the driving pedal again to open it around the rotating shaft again. Through this preferred structure, the cover can be prevented from closing during the cleaning and disinfection process, and it will not hinder the cover from opening again in the middle.

[0037] Preferably, the side wall of the cleaning and disinfection container is provided with a reset boss, which is located below the middle connecting rod; an unlocking spring is provided between the middle connecting rod and the reset boss. When the cleaning and disinfection is completed and the cleaning and disinfection pedal is left, the cleaning and disinfection pedal is reset upward, and the middle connecting rod is also reset upward under the drive of the unlocking spring, so that the pawl leaves the rotation range of the ratchet wheel, so that the cover can continue to be closed under the drive of the energy storage spring.

[0038] A preferred embodiment of the present invention is that a sedimentation and storage space for sediment and storage of sediment and other dirt is provided between the support portion and the bottom of the inner cavity wall of the cleaning and disinfection container. The purpose of such a setting is that in actual use, the sediment and other dirt attached to the soles will be mixed in the disinfectant solution, and move in and out of the liquid guide and sand settling holes together with the disinfectant solution to disinfect the soles. Compared with pure disinfectant solution, the turbid disinfectant solution not only reduces the disinfection effect, but also some impurities remaining in the disinfectant solution will re-adhere to the soles when the soles are separated from the disinfectant solution, affecting the cleanliness of the soles. In addition, the turbid disinfectant solution will block the liquid guide and sand settling holes, affecting the normal progress of the disinfection task. By setting the above-mentioned sedimentation storage space for dirt such as mud, the disinfectant liquid is divided into a layer of dirt such as mud at the bottom of the pool, a sedimentation transition layer between the layer of dirt such as mud and sand and the top of the support part, and a supernatant layer above the support part in the depth direction of the cleaning and disinfection container. The dirt such as mud in the layer of dirt such as mud will not be stirred up due to the disinfection action each time the disinfection is performed, so that the soles located on the cleaning and disinfection pedal are always immersed in the supernatant layer during disinfection. Therefore, on the one hand, it is ensured that the disinfection is always performed with pure disinfectant liquid, thereby improving the disinfection effect; on the other hand, it is ensured that dirt such as mud that has been detached during the cleaning and disinfection process will not adhere to the soles again, thereby avoiding secondary adhesion contamination to the soles.

[0039] Preferably, the support portion is composed of a limit plate, which is a separate structure from the cleaning and disinfection container, and the limit plate is placed on the bottom of the cleaning and disinfection container; the limit plate is a grid-like structure, and the grid space inside the limit plate constitutes the sediment storage space. During cleaning, the limit plate can provide a stable support for the brush plate, so the support effect is good. The limit plate is a separate structure from the cleaning and disinfection container. When in use, the limit plate can be laid in the cleaning and disinfection container to support and limit the brush plate; when the cleaning and disinfection container needs to be cleaned after disinfection, the cleaning and disinfection container and the limit plate can be cleaned separately by taking the limit plate out of the cleaning and disinfection container, thereby making the cleaning operation more convenient. In addition, the above-mentioned limit plate can be completed by a separate processing (such as casting, stamping, injection molding or blow molding), which greatly reduces the difficulty of processing and makes the setting of the support portion more convenient and feasible. The limiting plate can be formed by a plurality of vertical plates in a crisscross manner, and the space between the staggered flat plates constitutes a sedimentation and storage space for dirt such as mud and sand. It can also be formed by arranging a plurality of through holes on a flat plate.

[0040] Preferably, the support part is composed of a support column arranged at the bottom of the inner wall of the cleaning and disinfection container, and the support column is multiple, and the multiple support columns are evenly distributed on the bottom surface of the inner wall of the cleaning and disinfection container. The support column and the cleaning and disinfection container are an integrated structure, and the space formed between the multiple support columns constitutes the sedimentation and storage space of the dirt such as mud and sand. The integrated support column and the cleaning and disinfection container can be produced at one time, for example, by injection molding, eliminating the assembly step.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. By setting up the cover and the cover driving mechanism, when the disinfection task is completed, the closing mechanism can close the cover in time, which can avoid the waste caused by the volatilization of the disinfectant solution and also avoid the impact of the volatilized gas on the surrounding environment.

[0043] 2. The cover in the cleaning and disinfecting device is opened and closed very easily. The cover can be opened or closed by simply pressing the opening pedal or the closing pedal. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0067] Example 1

[0068] See also Figure 1-10 The cleaning and disinfection device for preventing the volatilization and evaporation of the disinfection liquid in this embodiment includes a cleaning and disinfection container 1 for containing the disinfection liquid, a cleaning and disinfection pedal 2 arranged in the cleaning and disinfection container 1, a cover plate 3 arranged at the opening of the cleaning and disinfection container 1, and a cover plate driving mechanism for driving the cover plate 3 to open or close.

[0069] One end of the cover plate 3 is connected to the edge of the cleaning and disinfection container 1 through a hinge structure; the cover plate driving mechanism includes an opening mechanism for causing the cover plate 3 to open and a closing mechanism for causing the cover plate 3 to close, the opening mechanism includes an opening pedal 4 and an opening power transmission mechanism, when the opening pedal 4 is pressed, the opening power transmission mechanism drives the cover plate 3 to flip upward around the hinge axis; the closing mechanism includes a closing pedal 5 and a closing power transmission mechanism, when the closing pedal 5 is pressed, the closing power transmission mechanism drives the cover plate 3 to flip downward around the hinge axis.

[0070] See also Figure 1-3 The opening power transmission mechanism includes a lifting plate 6, a transverse driving structure for driving the lifting plate 6 to move transversely parallel to the flipping plane of the cover plate 3, and a lifting structure that completes the lifting work with the transverse movement of the lifting plate 6; the lifting plate 6 is transversely arranged on one side of the cleaning and disinfection container 1, and its extension direction is parallel to the flipping plane of the cover plate 3; the lifting structure includes a lifting slope and a lifting boss 3-1, the lifting slope is arranged on the lifting plate 6, and the inclined direction is opposite to the driving direction of the transverse driving structure; the lifting boss 3-1 is arranged on the cover plate 3, located at the edge of the cover plate 3 close to the lifting plate 6, and extends downward. When the transverse driving mechanism drives the lifting plate 6 to move transversely, the lifting slope approaches and squeezes on the lifting boss 3-1, and as the transverse movement continues, the lifting boss 3-1 presses the lifting slope to move upward, that is, the lifting slope lifts the lifting boss 3-1 upward, so that the cover plate 3 flips upward around the hinge axis.

[0071] See also Figure 1-3The transverse driving structure includes a transverse driving rod 7 and a transverse driving groove 6-1; the transverse driving rod 7 is arranged on the opening pedal 4, and the transverse driving groove 6-1 is arranged on the end of the lifting plate 6 close to the opening pedal 4, and its opening faces upward; a transverse driving inclined surface is arranged at the opening. Generally, when the opening pedal 4 is stepped on downward, the transverse driving rod 7 moves downward and is pressed on the transverse driving inclined surface, so as the transverse driving rod 7 moves downward, the lifting plate 6 moves laterally in the direction of the transverse driving inclined surface, and then the cover plate 3 is lifted through the lifting structure.

[0072] See also Figure 1-3 The opening power transmission mechanism also includes a hydraulic support rod 8 for assisting the cover plate 3 to be fully opened or fully closed. One end of the hydraulic support rod 8 is hinged on the edge of the cleaning and disinfection container 1, and the other end is hinged on the cover plate 3. Since the lifting stroke of the lifting structure is limited, the cover plate 3 cannot be fully opened. Therefore, after the lifting structure lifts the cover plate 3, the hydraulic support rod 8 then drives the cover plate 3 upward to continue to flip upward until it is fully opened.

[0073] See also Figure 1-3 A first fixing seat 9 is provided below the opening pedal 4 , and a first return spring 10 for driving the opening pedal 4 to return to its original position is provided on the first fixing seat 9 ; a second return spring 11 is provided between the lifting plate 6 and the first fixing seat 9 .

[0074] See also Figure 1-3 The closing power transmission mechanism includes a rotary pressing arm 12 for driving the cover plate 3 to flip downward by rotating and pressing, and a rotary driving mechanism for driving the rotary pressing arm 12 to rotate; wherein the rotary pressing arm 12 is located outside the hinged joint between the cover plate 3 and the cleaning and disinfection container 1, the upper end is a pressing end, and the lower end is hinged on the mounting frame 13, and the mounting frame 13 is fixedly arranged on the edge of the cleaning and disinfection container 1; the rotary driving mechanism includes a second fixed seat 14, an intermediate push rod 15, an intermediate push block 16 and a The closing pedal 5, the second fixing seat 14 is fixedly arranged on the edge of the cleaning and disinfection container 1, and a vertically extending guide groove is provided therein; the lower end of the closing pedal 5 is a guide portion, and extends into the guide groove; the intermediate push block 16 is located on the side of the rotating pressing arm 12 away from the cover plate 3, and the lower end is hinged on the mounting frame 13; one end of the intermediate push rod 15 is fixedly connected to the closing pedal 5, and the other end is connected to the upper end of the intermediate push block 16; the pressing end of the rotating pressing arm 12 extends toward the cover plate 3. Through the above structure, when the closing pedal 5 is stepped down, the intermediate push rod 15 drives the intermediate push block 16 to rotate, thereby pushing the rotating pressing arm 12 to rotate toward the cover plate 3, and then prompting the cover plate 3 to close.

[0075] See also Figure 1-3A third return spring 17 is provided between the mounting bracket 13 and the rotating pressing arm 12 , and a fourth return spring 18 is provided between the mounting bracket 13 and the intermediate push block 16 .

[0076] See also Figure 4-10 The cleaning and disinfection container 1 is provided with a supporting portion for supporting the cleaning and disinfection pedal 2; the cleaning and disinfection pedal 2 includes a brush plate 2-1, a hair bundle 2-2 arranged on the brush plate 2-1 for brushing the soles of shoes, and a liquid guiding and sand settling hole 2-3 for disinfectant liquid and mud to enter and exit the brush plate 2-1, wherein the hair bundle 2-2 is a plurality of bundles, and the plurality of hair bundles 2-2 are arranged on the upper side of the brush plate 2-1, and the liquid guiding and sand settling holes 2-3 are a plurality of holes, and the plurality of liquid guiding and sand settling holes 2-3 are distributed in the gaps between the hair bundles 2-2 on the brush plate 2-1; in the stepped state, the brush plate 2-1 is supported on the supporting portion, and the liquid level of the disinfectant liquid reaches the hair bundle 2-2 on the upper side of the brush plate 2-1.

[0077] See also Figure 4-10 , the brush plate 2-1 is a lifting brush plate 2-1; in the non-trampling state, there is a movement space for the brush plate 2-1 to move up and down between the support part and the bottom of the cleaning and disinfection pedal 2; in the trampling state, the brush plate 2-1 moves downward to be supported on the support part, and the liquid level of the disinfectant reaches the hair bundle 2-2 on the upper side of the brush plate 2-1. The purpose of this arrangement is that, in the non-trampling state, the cleaning brush floats on the liquid level of the disinfectant liquid under the action of buoyancy, or is located at or above the liquid level under the support of the elastic element, thereby covering the disinfectant liquid to prevent the disinfectant liquid from volatilizing.

[0078] See also Figure 4-10A sedimentation and storage space 1-1 for sedimentation and storage of sediment and other dirt is provided between the support portion and the bottom of the inner cavity wall of the cleaning and disinfection container 1. The purpose of such a setting is that in actual use, the sediment and other dirt attached to the soles will be mixed in the disinfection liquid, and move in and out of the liquid guide and sand settling holes 2-3 with the disinfection liquid to disinfect the soles. Compared with the pure disinfection liquid, the turbid disinfection liquid not only reduces the disinfection effect, but also some impurities remaining in the disinfection liquid will re-adhere to the soles when the soles are separated from the disinfection liquid, affecting the cleanliness of the soles. In addition, the turbid disinfection liquid will block the liquid guide and sand settling holes 2-3, affecting the normal progress of the disinfection task. By setting the sedimentation storage space 1-1 for dirt such as mud, sand, etc., in the depth direction of the cleaning and disinfection container 1, the disinfectant liquid is sequentially divided into a layer of dirt such as mud at the bottom of the pool, a sedimentation transition layer between the layer of dirt such as mud and sand and the top of the support portion, and a supernatant layer above the support portion. The dirt such as mud in the layer of dirt such as mud will not be stirred up due to the disinfection action each time the disinfection is performed, so that the sole located on the cleaning and disinfection pedal 2 is always immersed in the supernatant layer during disinfection. Therefore, on the one hand, it is ensured that the disinfection is always performed with pure disinfectant liquid, thereby improving the disinfection effect; on the other hand, it is ensured that dirt such as mud that has been detached during the cleaning and disinfection process will not adhere to the sole again, thereby avoiding secondary adhesion contamination to the sole.

[0079] See also Figure 4-10 The support part is composed of a limit plate 19, which is a separate structure from the cleaning and disinfection container 1. The limit plate 19 is placed on the bottom of the cleaning and disinfection container 1; the limit plate 19 is a grid-like structure, and the grid space inside the limit plate 19 constitutes the sediment storage space 1-1. During cleaning, the limit plate 19 can play a stable supporting role for the brush plate 2-1, so the supporting effect is good. The limit plate 19 is a separate structure from the cleaning and disinfection container 1. When in use, the limit plate 19 is laid in the cleaning and disinfection container 1 to support and limit the brush plate 2-1; when the cleaning and disinfection container 1 needs to be cleaned after disinfection is completed, the cleaning and disinfection container 1 and the limit plate 19 are cleaned separately by taking the limit plate 19 out of the cleaning and disinfection container 1, so that the cleaning operation is more convenient. In addition, the above-mentioned limit plate 19 can be completed by a separate processing (such as casting, stamping, injection molding or blow molding), which greatly reduces the difficulty of processing and makes the setting of the support part more convenient and feasible. The limit plate 19 can be formed by multiple vertical plates in a criss-cross manner, and the space between the staggered flat plates constitutes the sedimentation storage space 1-1 for dirt such as mud and sand, or it can be formed by setting multiple through holes 19-1 on a flat plate.

[0080] See also Figure 1-3The cover plate 3 has two leaves, and the two cover plates 3 form a split structure. There are two lifting slopes, and the two lifting slopes are respectively arranged corresponding to the lifting bosses 3-1 on the two cover plates 3. There are two rotating pressing arms 12 and middle push blocks 16, and the two rotating pressing arms 12 and middle push blocks 16 are respectively arranged on the outside of the hinges between the two cover plates 3 and the cleaning and disinfection container 1. When working, the lateral driving mechanism drives the lifting plate 6 to move horizontally, so that the two lifting slopes are respectively in contact with the lifting bosses 3-1 on the two cover plates 3, and the two cover plates 3 are opened by applying a lifting force to the two lifting bosses 3-1; the two cover plates 3 are closed by driving the two rotating pressing arms 12 to make a pressing movement.

[0081] The working principle of the cleaning and disinfection device for preventing volatilization and evaporation of disinfection liquid in this embodiment is:

[0082] When the soles need to be disinfected and cleaned, the user can first step on the opening pedal 4, so that the opening power transmission mechanism drives the cover plate 3 to flip upward around the hinge axis until it is fully opened, and then the user places the soles in the cleaning and disinfection container 1, and steps on the cleaning and disinfection pedal 2, so that the cleaning and disinfection pedal 2 is immersed in the disinfection liquid, and the cleaning and disinfection pedal 2 and the disinfection liquid respectively clean and disinfect the soles. When the disinfection is completed, the user walks out of the cleaning and disinfection container 1, and then steps on the closing pedal 5, so that the closing power transmission mechanism drives the cover plate 3 to flip downward around the hinge axis, covering the cleaning and disinfection container 1, avoiding the waste caused by the volatilization of the disinfection liquid, and also avoiding the impact of the volatilized gas on the surrounding environment.

[0083] Example 2

[0084] See also Figure 11-12 , which is different from implementation 1, the cover plate 3 is one, and the opening pedal 4 and the closing pedal 5 are both located on the outside of the hinge between the cover plate 3 and the cleaning and disinfection container 1.

[0085] Example 3

[0086] Different from implementation 1, the opening power transmission mechanism and the closing power transmission mechanism include a driving cylinder and a fourth time relay, the plane where the driving cylinder extends is parallel to the flipping direction of the cover plate 3, and one end of the driving cylinder is hinged on the edge of the cleaning and disinfection container 1, and the other end is hinged on the cover plate 3; the opening pedal 4 and the closing pedal 5 are located above the switch of the fourth time relay. When working, stepping down the opening pedal 4 (closing pedal 5) touches the switch of the fourth time relay below, thereby closing the circuit, the driving cylinder starts working, and drives the cover plate 3 to flip up (flip down); at the same time, the fourth time relay calculates the time, and the circuit is disconnected until the cover plate 3 is flipped to the fully open state (closed state).

[0087] Example 4

[0088] See also Fig.13 , which is different from implementation 1, the transverse drive structure includes a transverse drive motor 20, a transverse transmission assembly and a first time relay 21, the transverse transmission assembly is connected to the lifting plate 6, and the switch of the first time relay 21 is located directly below the opening pedal 4; the first time relay 21 and the transverse drive motor 20 are electrically connected. During operation, the opening pedal 4 touches the switch of the first time relay 21 downward, starts the first time relay 21, and closes the circuit, so that the transverse drive motor 20 starts to work and drives the lifting plate 6 to move horizontally; at the same time, the first time relay 21 starts timing, and disconnects the circuit after a certain period of time (the time corresponds to the distance of the horizontal movement), so that the transverse drive motor 20 stops working, and the lifting structure has lifted the lifting plate 6.

[0089] Example 5

[0090] See also Fig.14 , which is different from implementation 1, the rotary drive mechanism includes a second fixed seat 14, an intermediate push rod 15 and the closing pedal 5, the second fixed seat 14 is fixedly arranged on the edge of the cleaning and disinfection container 1, and is provided with a vertically extending guide groove; the lower end of the closing pedal 5 is a guide portion, and extends into the guide groove; one end of the intermediate push rod 15 is fixedly connected to the closing pedal 5, and the other end extends to one side of the rotary pressing arm 12; the rotary pressing arm 12 is inclined toward the direction of the cover plate 3, and the vertical projection of the intermediate push rod 15 coincides with the rotary pressing arm 12. The principle of closing the cover 3 mentioned above is as follows: stepping on the closing pedal 5 downward causes the closing pedal 5 to move downward along the second fixed seat 14. Since the intermediate push rod 15 is fixedly connected to the closing pedal 5, when the closing pedal 5 moves downward, the intermediate push rod 15 is squeezed on the rotating pressing arm 12, thereby driving it to move in the direction of the cover 3. At this time, the hydraulic support rod 8 is in a non-working state, and the thrust of the rotating pressing arm 12 is greater than the resistance of the hydraulic support rod 8 itself, thereby causing the pressing end to push the cover 3, thereby closing the cover 3; since the pushing stroke of the rotating pressing arm 12 is limited, the cover 3 cannot be completely closed. Therefore, when the rotating pressing arm 12 stops driving, the angle between the cover 3 and the cleaning and disinfection container 1 is less than 90°, and the cover 3 will continue to rotate downward under the action of its own gravity, thereby completely closing the cover 3.

[0091] Example 6

[0092] See also Fig.15, different from implementation 1, a preferred solution of the present invention, wherein the opening power transmission mechanism includes a flip drive motor 22 and a second time relay 23, the flip drive motor 22 is connected to the cover plate 3 through a gear transmission assembly, the gear transmission assembly includes a driving gear 24 and a driven gear 25, the driving gear 24 is fixed on the output shaft of the flip drive motor 22, and the driven gear 25 is fixed on the cover plate 3; the rotation center of the driven gear 25 is the same as the rotation center of the cover plate 3; the switch of the second time relay 23 is located below the opening pedal 4, and the flip drive motor 22 is electrically connected to the second time relay 23. When working, the opening pedal 4 touches the switch of the second time relay 23 downward, starts the second time relay 23, and thus closes the circuit, so that the flip drive motor 22 starts to work and flips the cover plate 3; at the same time, the second time relay 23 starts timing, and disconnects the circuit after a certain period of time (the time corresponds to the flip angle), so that the flip drive motor 22 stops working, and is in a fully open state at this time.

[0093] The closing power transmission mechanism includes the flip drive motor 22 and the third time relay, the switch of the third time relay is located directly below the closing pedal 5; the flip drive motor 22 is electrically connected to two third time relays, and the two third time relays are respectively located on circuits connected in parallel with each other. Similarly, when the closing pedal 5 is stepped on, the third time relay is started, the corresponding circuit is closed, and the flip drive motor 22 is reversed, thereby driving the cover plate 3 to rotate in the closing direction; at the same time, the third time relay starts timing, and the circuit is disconnected after a certain time (the time corresponds to the flip angle), so that the flip drive motor 22 stops working, and is in a closed state at this time.

[0094] Example 7

[0095] See also Figure 19-23, which is different from the first embodiment, the cover driving mechanism includes a driving pedal 27 and an intermediate transmission mechanism, the intermediate transmission mechanism includes a rotating shaft 28 and a transmission assembly for transmitting the power of the driving pedal 27 to the rotating shaft 28, the rotating shaft 28 is fixedly connected to one end of the cover 3 through a fixed structure, and is connected to the side wall of the cleaning and disinfection container 1 through a hinged connection structure; the transmission assembly includes a rack 29 and a rotating gear 30 that mesh with each other, the rotating gear 30 is fixedly arranged on the rotating shaft 28, and is located between the cleaning and disinfection container 1 and the driving pedal 27; the rack 29 is vertically arranged on the driving pedal 27 and faces the rack 29. Through the above structure, when the driving pedal 27 is stepped down, the rack 29 moves downward, thereby driving the rotating gear 30 to rotate. Since the rotating gear 30 is located between the cleaning and disinfection container 1 and the driving pedal 27, as the rack 29 moves downward, the rotating gear 30 rotates in the direction of opening the cover 3, thereby driving the cover 3 to open upward around the rotating shaft 28. In the preferred embodiment, by using the gear and rack 29 for transmission and setting a reasonable transmission ratio, there is enough travel to drive the cover plate 3 to open to a desired angle without the need for other auxiliary driving mechanisms.

[0096] Along the direction of entering the cleaning and disinfecting container 1 , the rotation axis 28 is located on the right side of the cleaning and disinfecting container 1 . When the cover plate 3 is opened, it rotates around the rotation axis 28 toward the right side of the cleaning and disinfecting container 1 .

[0097] A pedal fixing seat 31 is provided below the driving pedal 27, and a limiting guide hole 31-1 extends vertically on the pedal fixing seat 31; the top of the driving pedal 27 is a pedal portion, and a pedal spring 32 is provided between the pedal portion and the upper surface of the pedal fixing seat 31; the rotating gear 30 is fixed on the rotating shaft 28 through a one-way bearing, and the locking direction of the one-way bearing is the opening direction of the cover plate 3. Through the above structure, when the driving pedal 27 is released, the driving pedal 27 is reset upward under the action of the pedal spring 32 to prepare for the next use; wherein, since the rack 29 is arranged on the driving pedal 27 and the rack 29 is meshed with the rotating gear 30, generally, when the rack 29 moves, the rotating gear 30 will also rotate; for this reason, the preferred embodiment adopts a one-way bearing as an intermediate connecting piece connecting the rotating gear 30 and the rotating shaft 28, and its locking direction is the opening direction of the cover 3, so that when the driving pedal 27 moves downward, the driving direction of the rack 29 is the locking direction of the one-way bearing, thereby being able to drive the rotating shaft 28 to rotate; when the driving pedal 27 is moved upward and reset, the driving direction of the rack 29 is the free rotation direction of the one-way bearing, so the rotating gear 30 only rotates around the rotating shaft 28, and cannot form an effective drive, thereby not driving the cover 3 to close.

[0098] The cover driving mechanism also includes a closer 33 for driving the cover 3 to close autonomously. The closer 33 is arranged at one end of the rotating shaft 28, and its extension direction is perpendicular to the extension direction of the rotating shaft 28. The closer 33 includes a housing, a transmission shaft, an energy storage spring and a damping member. The transmission shaft is provided with a spring driving cam for driving the energy storage spring to compress and store energy, and a damping driving cam for compressing the damping member. The transmission shaft is concentric with the rotating shaft 28 and is fixedly connected to the rotating shaft 28. When the rotating shaft 28 moves in the direction of opening the cover 3, the closer 33 moves in the direction of opening the cover 3. When rotating, the spring driving cam rotates with the transmission shaft and compresses the energy storage spring, the damping driving cam moves away from the compression damping member, and the compression damping member extends; when the rotating shaft 28 rotates in the direction of closing the cover plate 3, the spring driving cam moves away from the energy storage spring, the energy storage spring releases potential energy to recover, and drives the transmission shaft to rotate in the direction of closing the cover plate 3, driving the cover plate 3 to close, and at the same time, the damping driving cam compresses the damping member with the transmission shaft, and the damping member resists the potential energy of the energy storage spring through its own damping structure, so that the cover plate 3 is slowly closed. For a more detailed implementation, please refer to a vertical closer disclosed in the invention patent with application publication number CN106988637A.

[0099] See also Figure 19-23 A one-way rotation mechanism is provided between the cleaning and disinfection pedal 2 and the rotating shaft 28, and the one-way rotation mechanism is a ratchet mechanism, including a ratchet 34 and a pawl 35; the ratchet 34 is fixedly arranged on the rotating shaft 28, and its tooth direction is the same as the opening direction of the cover 3; the pawl 35 is arranged above the ratchet 34, and is connected to the cleaning and disinfection pedal 2 in the cleaning and disinfection container 1 through an intermediate connecting rod 36, one end of the intermediate connecting rod 36 is hinged to the pawl 35, and the other end passes through the cleaning and disinfection container 1 and extends below the cleaning and disinfection pedal 2; a torsion spring is provided between the pawl 35 and the intermediate connecting rod 36 for urging the pawl 35 to be in a fixed posture; when the cleaning and disinfection pedal 2 is in a non-stepped state, the pawl 35 is outside the rotation range of the ratchet 34; when the cleaning and disinfection pedal 2 is in a stepped state, the pawl 35 enters the rotation range of the ratchet 34.

[0100] Generally, when the cover plate 3 is opened, the cover plate 3 will automatically close under the action of the closer 33. In order to prevent the cover plate 3 from closing during the cleaning and disinfection process, the inventor proposes this preferred solution. In this preferred solution, when the cleaning and disinfection pedal 2 is stepped on, the intermediate connecting rod 36 located below will be driven to move downward, so that the other end of the intermediate connecting rod 36 is the pawl 35 that enters the rotation range of the ratchet 34. Since the tooth direction of the ratchet 34 is the same as the opening direction of the cover plate 3, that is, the closing direction of the cover plate 3 is the direction in which the pawl 35 locks the ratchet 34, the pawl 35 is directly stuck between the ratchet teeth of the ratchet 34, locking the ratchet 34, so that the rotating shaft 28 stops rotating and the cover plate 3 stops closing, so as to continue cleaning and disinfection; in addition, when the automatic closing angle of the cover plate 3 is too large and affects the cleaning and disinfection, the user can push the cover plate 3 by hand or step on the driving pedal 27 again to open it around the rotating shaft 28 again. This preferred structure can prevent the cover plate 3 from closing during the cleaning and disinfection process, and will not hinder the cover plate 3 from opening again during the process.

[0101] The side wall of the cleaning and disinfection container 1 is provided with a reset boss, which is located below the middle connecting rod 36; an unlocking spring 37 is provided between the middle connecting rod 36 and the reset boss. When the cleaning and disinfection is completed and the cleaning and disinfection pedal 2 is left, the cleaning and disinfection pedal 2 is reset upward, and the middle connecting rod 36 is also reset upward driven by the unlocking spring 37, so that the pawl 35 leaves the rotation range of the ratchet wheel 34, so that the cover plate 3 can continue to be closed under the drive of the energy storage spring of the closer 33.

[0102] Example 8

[0103] See also Figure 16-18 , which is different from the embodiment 1, the support part is composed of a support column 26 arranged at the bottom of the inner cavity wall of the cleaning and disinfection container 1, and the support column 26 is multiple, and the multiple support columns 26 are evenly distributed on the bottom surface of the inner cavity of the cleaning and disinfection container 1. The support column 26 and the cleaning and disinfection container 1 are an integrated structure, and the space formed between the multiple support columns 26 constitutes the sedimentation storage space 1-1 for dirt such as mud and sand. The support column 26 and the cleaning and disinfection container 1 of the integrated structure can be produced at one time, for example, by injection molding, eliminating the assembly step.

In the non-stepping state, the height of the driving pedal 27 is not higher than the cover plate 3.

[0108] The switch control module can also be a processing module that can realize automatic sensing. By setting the automatic sensing module, when the user approaches the cleaning and disinfection container 1, the automatic sensing module sends an opening signal to the automatic drive motor 40, so that the automatic drive motor 40 can drive the cover 3 to open; when the user leaves the cleaning and disinfection container 1, the automatic sensing module sends a closing signal to the automatic drive motor 40, so that the automatic drive motor 40 can drive the cover 3 to close. The specific automatic sensing module can be an infrared detection module, etc.
