[0007] The present invention also provides a simple brushing device, including the above-mentioned bracket body. An inner brushing portion facing outward for brushing the inner wall surface of the container body is provided on the inner brush holder. An outer brushing portion facing inward for brushing the outer wall surface of the container body is provided on the outer brush holder.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] 1. The present invention provides a bracket for use in a container cleaning machine. The bracket provides a bracket for a handleless container body that can be used in a container cleaning machine for brushing by means of an inner brush holder and an outer brush holder of the bracket body and a supporting structure. When brushing, the wall of the handleless container body is located in a brushing wall space between the inner brush holder and the outer brush holder, so that the handleless container body can be brushed by rotating the container body or rotating the bracket. The structure is simple and easy to install and use.

[0010] 2. The present invention also provides a scrubbing device for use in a container cleaning machine, which can scrub the inner wall, outer wall and inner bottom of a handleless container simultaneously, thereby shortening the scrubbing time, increasing scrubbing efficiency, and making the scrubbing more comprehensive, cleaner and more hygienic.

[0011] 3. The present invention also provides a simple brushing device for use in a container cleaning machine. The most significant feature of the device is that the brushing parts such as bristles used for brushing the inner and outer walls of a handleless container are directly arranged on the inner brush holder and the outer brush holder. The device can also be regarded as directly connecting the inner and outer wall brushes into a brushing device through a connecting seat, which makes the structure of the brushing device simpler and helps to reduce manufacturing costs.

[0012] 4. The scrubbing device provided by the present invention enables the handleless container to be scrubbed in an inverted manner, so that the loading and unloading of the container is very convenient, and the inner cavity of the container does not need to be soaked in washing water while spraying and scrubbing, so that scrubbing is cleaner and more hygienic.

[0013] 5. The scrubbing device provided by the present invention can be detachable, so it can be taken out and dried, avoiding the breeding of bacteria and mildew when it is left in the container cleaning machine due to residual water on the scrubbing part. At the same time, different users can use their own dedicated scrubbing devices, avoiding unsanitary conditions caused by using the same scrubbing device.

[0014] 6. The support and scrubbing device provided by the present invention adopt the method of installing the supporting structure on the support in cooperation with the main structure on the container cleaning machine. Since the support and the scrubbing device can be detachable, different types of containers can be installed on the same container cleaning machine using different scrubbing devices for scrubbing. Therefore, the present invention can expand the application scope of the scrubbing device and the container cleaning machine. For example, drinking cups and milk bottles, many of which have straight cylindrical cavities, and milk bottles generally have closed ends, can use their own scrubbing devices respectively.

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] A handleless container or a handleless container body, where "handleless" means without a handle during the brushing process, that is, the container or the container body does not carry a handle during the brushing process. Therefore, "handleless" means without a handle or with a detachable handle.

[0028] "And / or" or "or / and" includes any one and all combinations of the listed items. For example, A and / or B is expressed as: A, B, A + B, these three cases.

[0029] For the marks in the drawings, when there are the same or symmetrical structural features in the same embodiment or the same drawing, for the sake of simplicity, sometimes only one place is marked. The directions of inside, inner and outside in the text refer to the circumference centered on the positioning center line. The direction towards the center of the circle is inside or inner, and vice versa is outside. The radial direction refers to the radial direction of this circumference, and the axial direction refers to the positioning center line or the direction parallel to the positioning center line.

[0030] The present invention is realized through the following technical solutions:

[0031] As shown in FIGS. 1 to 19, a bracket applied to a container cleaning machine includes a bracket body whose own positioning center line coincides with the center line 17 of the main structure on the cleaning machine. The bracket body includes an inner brush holder for installing an inner wall brush, an outer brush holder for installing an outer wall brush, and a connecting structure for connecting the inner brush holder and the outer brush holder. And a brush wall space centered on the positioning center line is formed between the inner brush holder and the outer brush holder; the bracket body further includes a secondary holding structure provided on the inner brush holder and / or the outer brush holder for cooperating with the main structure on the cleaning machine for installation and enabling the cleaning machine to carry or prevent the bracket body from rotating around the positioning center line 17. The present invention provides a bracket applied to a container cleaning machine, which is installed with the brushing container through the bracket body, and through the settings of the inner brush holder, the outer brush holder and the secondary holding structure, provides a cleaning bracket that can be applied to the cleaning machine for a handleless container. During cleaning, the container wall part of the handleless container body is located in the brush wall space between the inner brush holder and the outer brush holder. Thus, the effect of cleaning the container body can be achieved by rotating the container body or rotating the inner brush holder and the outer brush holder, and the structure is simple and convenient for installation and use.

[0032] The above-mentioned main structure of the cleaning machine is a structure provided on the cleaning machine and installed with the same positioning center line as the bracket body, which can be realized by an axis structure, etc., and can make corresponding changes according to the change of the secondary holding structure, and will be listed again in the following embodiments.

[0033] Furthermore, as shown in Figure 1, the bracket body is detachably mounted to the main holding structure of the cleaning machine through the secondary holding structure. The cleaning machine cooperates with the secondary holding structure on the bracket body through the main holding structure (shown as the main holding shaft in Figure 1), so as to facilitate driving the bracket body to rotate or only rotating the container, keeping the bracket body stationary, thereby achieving the effect of brushing the container. And the detachable connection is adopted, which is convenient for replacement and disassembly.

[0034] Moreover, the inner brush frame includes at least two inner upright frames 111 distributed along the positioning center line, and the outer brush frame includes at least two outer upright frames 121 distributed along the positioning center line. The inner upright frames 111 are used to install the inner wall brush and the inner bottom brush, and the outer upright frames 121 are used to install the outer wall brush; multiple inner upright frames can also be arranged in a circular distribution centered on the positioning center line, and the outer upright frames can be arranged at any angle on the circumference with the positioning center line 17 as the center, so as to form a brushing space on the circumference to meet the requirements of brushing and cleaning the inner and outer walls and the inner bottom surface of the handleless container body. The multiple inner upright frames can be set at different distances from the positioning center line, and only by forming a circular brush surface with the bristles of the inner brush walls connected thereto can the cleaning effect be achieved. For example, taking the setting of two inner upright frames as an example, the left inner upright frame is at a longer distance from the positioning center line, and the right inner upright frame is at a shorter distance from the positioning center line. By setting the bristles of the inner brush wall connected to the left inner upright frame to be shorter than those of the right side (since the bristles of the inner wall brush are arranged outward to clean the inside of the container), the brush surface of the bristles is kept on the same circumferential surface centered on the positioning center line.

[0035] In this application, the structure of the secondary holding structure is: at least including a secondary holding hole provided on the inner brush frame. The secondary holding structure mainly cooperates with the main holding structure through the secondary holding hole 131. The requirements for the secondary holding hole are, firstly, to be installed in cooperation with the main holding structure with the same positioning center line, and secondly, to be installed with limited circumferential relative movement with the main holding structure (which can also be understood as torque-transmitting installation). In addition, the secondary holding hole 131 has a secondary holding surface 1311, and the secondary holding surface is the hole shape of the secondary holding hole. Therefore, the secondary holding hole can adopt a polygonal hole, an elliptical hole or other non-circular holes, all of which can achieve the above purposes, and other structures can also be adopted. Multiple ones can also be set. Or the secondary holding structure further includes a secondary holding arm 132, the secondary holding hole 131 is a circular hole, and the center of the circular hole coincides with the positioning center line. This specific structure will be specifically described in the following embodiments.

[0036] Specifically, the following embodiments can all be adopted for the bracket body in the solution of this application;

[0037] First Embodiment of the Bracket Body: As shown in FIGS. 1 to 3, the inner brush holder includes two inner vertical frames 111 and 112 evenly arranged along the positioning center line. The outer brush holder includes two outer vertical frames 121 and 122 evenly arranged along the positioning center line. The lower ends of the inner vertical frames 111 and 112 are provided with connecting parts 1232 extending outwards. Outer brush holder connectors 124 and 125 are provided at the outer ends of the connecting parts 1232. The lower ends of the outer vertical frames 121 and 122 are provided with inner and outer connecting parts 128 inserted into the outer brush holder connectors 124 and 125.

[0038] The inner brush holder 11 is used to install the inner wall brush 14 and the inner bottom brush 16. The outer brush holder 12 is used to install the outer wall brush 15. The inner bottom brush 16 can be arranged at the upper end of the inner wall brush 14. The brush surface 142 of the inner wall brush 14 is arranged on the radial outer surface of the inner wall brush body 141. The brush surfaces 152 and 153 of the outer wall brush 15 are arranged on the radial inner surface of the outer wall brush body 151. The brush surface 162 of the inner bottom brush 16 is arranged on the upper surface of the inner bottom brush body 161. The inner wall brush 14, the outer wall brush 15 and the inner bottom brush 16 are respectively used to brush the inner wall surface, the outer wall surface and the inner bottom surface of the container body 18 during rotation. The inner bottom brush can also be installed at the upper end of the inner brush holder;

[0039] The inner brush holder 11 is arranged with the positioning center line 17 as the positioning center. The outer brush holder 12 is arranged outside the inner brush holder 11 with the positioning center line 17 as the positioning center. The lower end of the inner brush holder 11 is fixedly connected to the lower end of the outer brush holder 12 to form the bottom of the brush holder.

[0040] Moreover, a handle 1231 is further provided at the upper end of the outer vertical frame. On the one hand, it is used to connect and fix the upper end of the outer vertical frame. On the other hand, it is convenient for the user to pick up and place for disassembly and installation. The handle part can also be used as a split installation structure, and the split structure will be supplemented in the subsequent embodiments.

[0041] Specifically, the connection structure between the outer brush holder and the inner brush holder is as follows: T-shaped clamping grooves 126 are provided on the outer brush holder connectors 124 and 125. The outer connecting part 128 is a clamping convex protruding from both sides of the vertical frame connector and cooperating with the T-shaped clamping groove 126. The inner and outer brush holders can be fixed together through the clamping groove, the clamping convex and the screw holes to form the bracket shown in FIG. 3. A handle part 1231 is provided at the upper end of the outer vertical frame 121, which is convenient for the picking up and placing of the container brushing device 1 and can also simplify the structures of the outer vertical frames 121 and 122. Each component in this example can be made of plastic.

[0042] For the convenience of the installation and replacement of the inner wall brush, and to improve the installation efficiency, a limiting slot hole structure for the limiting installation of the inner wall brush can be provided on the inner brush holder. The limiting installation enables the inner wall brush to be fixedly installed or movably installed. The advantage of the movable installation is that an elastic member can be added between the inner wall brush and the inner brush holder. The setting of the elastic member will be described later.

[0043] In Embodiment 1, the installation structure of the inner and outer wall brushes is as follows: at the upper end of the inner vertical frame 111, there is a card slot 117 extending outward for the inner wall brush to pass through, and on the connecting portion 1232, there is a through hole opposite to the card slot 117; the card slot 117 is composed of two oppositely arranged lateral slot stoppers 1171, and the outer ends of the two lateral slot stoppers form an outward opening; when installing the inner wall brush 14, insert the inner wall brush 14 downward along the card slot 117 and the through hole from top to bottom, and then use a nut 145 to fix the lower fixing member 141 of the inner wall brush 14 below the axial through hole (it can also be fixed by means of a snap ring). At this time, the card slot 117 with two lateral slot stoppers limits the two wings 142 of the inner wall brush 14 in the radial direction, and the through hole 116 located below limits the lower fixing member 141 of the inner wall brush 14, so the inner wall brush can be movably limited or fixed.

[0044] On the inner side surfaces of the outer vertical frames 121 and 122, there are limiting slots 127 for installing the outer wall brush 15 with the slot openings facing inward, and at the upper end of the limiting slot 127, there is a radial slot stopper 1233. During installation, first place the outer wall brush 15 into the limiting slot 127, and then fix the inner and outer brush holders together. The inner wall brush can be installed first or later. It should be noted that the outer brush holder can also be provided with a limiting slot hole structure similar to that on the inner brush holder, and the limiting installation method of the inner wall brush can be used to install the outer wall brush.

[0045] In Embodiment 1, the structure of the follower structure is as follows: the follower structure is a connecting block provided between the two inner vertical frames 111 and 112 with a follower hole 131. The follower structure mainly cooperates with the main holding structure through the follower hole 131. The requirements for the follower hole are, firstly, to be installed in cooperation with the same positioning center line of the main holding structure, and secondly, to be installed with limited circumferential relative movement with respect to the main holding structure.

[0046] In Embodiment 2 of the bracket body, as shown in Figure 4, the difference from Embodiment 1 is that the inner brush holder and the outer brush holder are integrated, and the lower ends of the inner vertical frames 111 and 112 are bent outward and then upward to form the outer vertical frames 121 and 122; the connecting structure includes the bending between the inner and outer vertical frames.

[0047] The connection structure includes a brush holder base 218 provided at the lower ends of the inner brush holder and the outer brush holder, and a gland 225 provided at the upper ends of the inner brush holder and the outer brush holder.

[0048] The upper ends of the two inner vertical frames are also connected by bending, that is, in this embodiment, the inner and outer vertical frames are formed by bending a long strip of metal sheet. Moreover, in this solution, in order to fix the inner and outer brush holders, a brush holder base and a gland are added to fix their upper and lower ends, making the entire structure more firm and reliable after installation.

[0049] Specifically, the lower ends of the inner vertical frame 111 and the outer vertical frame 121 are provided with limit clamping protrusions 213, and the brush holder base 218 is provided with a card slot for the limit clamping protrusions 213 and the bending part between the inner vertical frame 111 and the outer vertical frame 121 to extend into. The specific structure of the card slot includes an inner card slot for accommodating the limit clamping protrusion at the lower end of the inner vertical frame 111, an outer card slot for accommodating the limit clamping protrusion at the lower end of the outer vertical frame, and a slot connecting the outer card slot and the inner card slot for accommodating the bending part. Then, the brush holder body can be fixed to the base through connecting parts such as screws.

[0050] The specific structure of the gland is as follows: This structure is a split installation structure, including an inner cover 224. The inner cover 224 is provided with a T-shaped card slot and screw holes 2244, and the lateral notch is larger than the width of the outer vertical frame 221. The upper end of the outer vertical frame 221 is provided with a T-shaped clamping protrusion 222 corresponding to the T-shaped card slot 2241. During installation, the upper parts of the two outer vertical frames 121 are slightly pressed inward towards the middle, and then the inner cover 224 is used to clamp the outer vertical frame 121 into the T-shaped card slot from bottom to top until it is clamped with the T-shaped clamping protrusion 222. Then, the gland 225 is covered, and the inner cover 224 and the handle gland 225 are fixed from bottom to top through the screw holes 2244 with screws. At this time, the T-shaped clamping protrusion 222 is clamped in the T-shaped card slot and is pressed by the inner flange of the gland 225.

[0051] The secondary holding structure in Embodiment 2 is as follows: The secondary holding structure includes a lower secondary holding member 232 provided on the brush holder base 218, and an upper secondary holding member 231 connected between the two inner vertical frames 211 and 212. Both the upper and lower secondary holding members are provided with secondary holding holes 131, and secondary holding surfaces are provided in the secondary holding holes. Moreover, on both sides of the upper secondary holding member 231, there are provided retaining blocks 2314 that extend towards the inner vertical frame direction to form limiting grooves. On the inner vertical frame 211, there are provided a T-shaped clamping protrusion 212 and screw holes 214. On the secondary holding hole structure 231, there are provided corresponding T-shaped clamping grooves and screw holes, and the notch of the lateral retaining block 2314 is larger than the width of the inner vertical frame 111. During installation, the lower parts of the two inner vertical frames 111 are slightly separated to both sides, and then the secondary holding hole structure 231 clamps the inner vertical frame 111 into the T-shaped clamping groove from bottom to top until it is clamped with the T-shaped clamping protrusion 212. Then, the screw is horizontally passed through the operation hole 227 on the outer vertical frame 121 and fastened with a screw, thereby fixing the secondary holding hole structure 231 on the inner brush holder 21. The inner and outer brush holders can be made by bending stainless steel or aluminum alloy, and the secondary holding hole structure, gland, etc. can be made of plastic.

[0052] For the support body in Embodiment 3, as shown in Figure 5, the main difference from Embodiment 2 is that there is also an inclined folding portion 312 that inclines inwards between the inner vertical frame 111 and the lower limiting clamping protrusion 213, and the upper end of the limiting clamping protrusion 213 is connected to the lower end of the inner vertical frame 111 through the inclined folding portion 312. This enables the bristles of the inner wall brush to be set longer, and this solution is more suitable for cleaning a container body with a closed mouth. The connection method between it and the chassis and the gland can refer to the structure in Embodiment 2.

[0053] In addition, above the upper secondary holding member, there is also provided a bottom brush connecting member 3312 for installing the bottom brush. The specific structure is described in detail in Embodiment 2 of the inner bottom brush.

[0054] Fourth embodiment of the bracket body. As shown in Fig. 6, the inner brush holder includes an upper inner brush holder connecting block 411, a lower inner brush holder connecting block 412, and an inner vertical frame 413 connected between the upper inner brush holder connecting block 411 and the lower inner brush holder connecting block 412; the outer brush holder includes an upper outer brush holder connecting block 421, a lower outer brush holder connecting block 422, and an outer vertical frame 423 connected between the upper outer brush holder connecting block 421 and the lower outer brush holder connecting block 422; the connecting structure includes a base connecting the lower inner brush holder connecting block 412 and the lower outer brush holder connecting block 422; the holding structure includes a lower holding hole provided on the base and an upper holding block provided on the upper inner frame connecting block 411. The upper inner brush holder connecting block 411 and the lower inner brush holder connecting block 412, as well as the upper outer brush holder connecting block 421 and the lower outer brush holder connecting block 422, can be made of plastic, and the inner vertical frame 413 and the outer vertical frame 423 can be made of metal bars, such as stainless steel bars or aluminum alloy bars. First, make the upper and lower parts of the inner and outer brush holders. The lower parts of the inner and outer brush holders can be made into one piece. During installation, first use the upper end gland or the handle part 425 to fixedly connect the two left and right upper outer brush holder connecting blocks 421, use the inner vertical frame 413 to fixedly connect the upper inner brush holder connecting block 411 and the lower inner brush holder connecting block 412, and then use the outer vertical frame 423 to fixedly connect the two upper outer brush holder connecting blocks 421 that have been fixedly connected together and the lower inner brush holder connecting blocks 412 on both sides.

[0055] In the fourth embodiment of the bracket body, radial elastic members can also be provided on the inner and outer brush holders. By providing a radial elastic member for the inner brush holder, the inner wall brush can be elastically installed in the radial direction. By providing a radial elastic member for the outer brush holder, the outer wall brush can be elastically installed in the radial direction.

[0056] In addition, an outer wall brush limit groove stop is provided on the inner side of the groove on the upper outer brush holder connecting block 421 and the lower outer brush holder connecting block 422, and a gland 424 is also provided on the outer side of the upper outer brush holder connecting block 421 and connected to the upper outer brush holder connecting block 421. After the bracket is installed, the inner and outer wall brushes are installed. The installation of the inner wall brush is the same as that in Embodiment 1 of the bracket. After the outer wall brush is inserted into the limit groove, cover the outer wall brush gland 424, and then fix the outer wall brush gland 424 from bottom to top with screws through the screw holes 426 on both sides.

[0057] Fifth embodiment of the bracket body. As shown in FIGS. 7 and 8, the structures of its inner and outer brush holders are the same as those in the second embodiment. The difference from the second embodiment is that a secondary holding arm 132 is further provided on the brush holder base 218, which can be regarded as an embodiment of the secondary holding structure adopting the secondary holding arm structure. The secondary holding arm 132 is a convex block extending outward toward the outer side. FIG. 7 is a structural diagram installed on the main holding structure of the cleaning machine. It can be seen from the figure that during cleaning, the positioning round shaft 591 is driven to rotate, thereby driving the main holding arm 592 fixed thereon to rotate. When the main holding arm 592 touches the secondary holding arm 132, it contacts the latter, thereby carrying the latter to rotate together. Since the positioning round hole structures 531 and 532 are slidably sleeved on the positioning round shaft 591 and the secondary holding holes thereon are round holes, the container brush device 5 is carried to rotate around the center line 57. It should be noted that at this time, there is no relative rotational movement between the positioning round shaft 591 and the container brush device 5. In the fifth embodiment of the bracket, since the lower positioning round hole structure 532 is fixed on the inner brush holder 51, the secondary holding arm 132 can also be described as being provided at the lower part of the inner brush holder 51. The secondary holding arm 132 can also be provided at different positions.

[0058] Sixth embodiment of the bracket body. As shown in FIGS. 9 and 10, the inner brush holder includes three inner upright frames 111 distributed on the circumference along the positioning center line; the outer brush holder includes three outer upright frames 121 distributed on the circumference along the positioning center line. The lower ends of the inner upright frames 111 are bent and connected to the lower ends of the outer upright frames 121; the connecting structure includes a brush holder base 626 provided at the lower ends of the inner and outer brush holders and a gland 625 provided at the upper ends of the inner and outer brush holders. The difference from the above embodiments is that both the inner and outer brush holders are arranged in multiple numbers distributed along the circumference of the center line. It can achieve a better brushing effect. The connection method of the bracket and the secondary holding structure can refer to the third embodiment or the second embodiment.

[0059] Seventh embodiment of the bracket body. As shown in FIGS. 11 and 12, the difference from the first embodiment is that the secondary holding structure is not provided as a secondary holding block. The secondary holding structure includes a secondary holding member 732 with an assembly hole provided on the outer sides of at least one of the outer upright frame connectors 124 and 125. This secondary holding member can be regarded as a different structural embodiment of the secondary holding arm, and there is also a shaft hole 792 with an axis coinciding with the positioning center line provided between the two inner upright frames. The through hole in the middle can be set as a round hole (i.e., the secondary holding hole), which is only used for installation along the positioning center line. By providing the secondary holding member on one side, the main holding shaft 793 on the cleaning machine is inserted into the through hole of the secondary holding member, so that it can be carried to move synchronously.

[0060] Eighth embodiment of the support body. As shown in FIG. 13, the difference from the seventh embodiment is that the holding structure includes a holding insertion part 133 arranged between the two inner standing frames and extending downward. It can be regarded as an embodiment where the holding structure adopts a shaft-type holding insertion part. The outer peripheral surface of the holding insertion part 133 is a holding surface, and a polygon surface is adopted in this solution. Other structures are similar to those in the first embodiment. Correspondingly, the main holding structure of the container brush is the main holding pipe structure. A main holding surface corresponding to the holding surface is arranged in the main holding pipe structure. When the main holding pipe structure is driven to rotate, it will drive the container brush device to rotate through the holding member structure.

[0061] Ninth embodiment of the support body. As shown in FIG. 14, the difference from the seventh embodiment is that the holding structure includes a holding member 933 with an assembly hole arranged on at least the outer side of one of the outer standing frames, and an upper shaft hole 931 and a lower shaft hole 932 with axes coinciding with the positioning center line are also arranged between the two inner standing frames. The main holding structure of the container brush includes a positioning circular shaft structure and a main holding member structure. The main holding member structure is fixed on the driving sleeve, and the positioning circular shaft structure is fixedly and sealingly inserted into the driving sleeve. The positioning circular shaft structure plays a role in rotational positioning. When the driving sleeve is driven to rotate, it drives the main holding member structure to rotate, thereby driving the container brush device to rotate.

[0062] Tenth embodiment of the support body. As shown in FIGS. 15 to 17, a connecting arm (i.e., the main holding structure) installed on the container cleaning machine is used. The connecting arm is provided with clamping positions 1091 and 1092 for clamping the outer standing frame connectors 124 and 125. When the rotating shaft is driven to rotate, it drives the connecting arm to rotate, thereby driving the support to rotate. This solution can be regarded as another embodiment where the holding structure adopts a holding insertion part. The holding structure is manifested as the outer standing frame connectors on both sides of the support body. After being installed through the connecting arm, it is possible to perform co-positioning center line installation without using the middle holding hole or through hole.

[0063] In addition, as shown in FIG. 18, it can be regarded as different embodiments where the holding structure adopts a holding insertion part. It also utilizes the assembly of the main holding structure and the holding insertion parts on both sides of the support body to achieve the effect of co-positioning center line installation. In this solution, the holding structure is manifested as sleeves arranged on both sides of the outer standing frame. The sleeve structure can refer to the structure of the holding member 732 in the seventh embodiment (FIG. 12). The installation shafts extending from both sides of the main holding structure are inserted into the sleeves for installation, or it can be replaced by installation shafts extending downward on both sides of the outer standing frame, and the main holding structure adopts sleeves for mating installation.

[0064] From the description of the technical solutions of the above-mentioned various stent implementation examples, it can be known that the holding structure is arranged on the inner brush holder and / or the outer brush holder with the positioning center line as the positioning center. The holding structure cooperates with the container brush holding structure of the container washing machine, so that the container brush device can be concentrically installed on the container brush holding structure and held together in the circumferential direction. This holding enables the container brush holding structure to carry or prevent the container brush device from rotating around the positioning center line.

[0065] The above-mentioned various stent implementation examples list various forms of the inner brush holder and the outer brush holder, as well as their connection relationships. In the examples, the inner and outer brush holders basically adopt the vertical frame or the scheme of being divided into upper and lower parts, mainly to reduce the occlusion of the inner and outer wall surfaces of the container body, so that the washing water can be sprayed more fully. Therefore, it should be understood that there are other suitable forms for the inner and outer brush holders, and the above examples are only part of the preferred implementation methods of the inner and outer brush holders. The inner and outer brush holders provide support for the installation of the inner and outer wall brushes and the inner bottom brush, but the inner and outer wall brushes can be installed without relying on the inner and outer vertical frames.

[0066] In the above examples, the inner and outer brush holders adopt the scheme of symmetrically setting with the positioning center line as the center or evenly distributing around the positioning center line. It should be understood that this is also one of the preferred schemes for the inner and outer brush holders. Since the brush wall space is jointly constructed by the mutual cooperation of the inner and outer brush holders and the inner and outer wall brushes, and at least one of the inner wall brush, the outer wall brush and the inner bottom brush is sufficient, the inner brush holder and the outer brush holder can also be asymmetrically set and unevenly arranged. It should be understood that the positioning center line is only for the need of technical solution description and does not represent the structural characteristics of the entity.

[0067] In the above examples, the example with the brush holder base is more suitable for the container brush holding structure scheme in which the main shaft has an inner cavity and is provided with spray holes, that is, the inner wall surface and the inner bottom surface of the container body are sprayed and washed from the main shaft.

[0068] The present invention also provides a brushing device applied to a container washing machine, including a bracket body, an inner wall brush arranged on the inner brush holder, and an outer wall brush arranged on the outer brush holder; the inner wall brush includes an inner brush handle 141 cooperatively installed with the inner brush holder, and an inner brushing part 142 arranged on the inner brush handle 141 and facing outward for brushing the inner wall surface of the container body; the outer wall brush includes an outer brush handle 151 cooperatively installed with the outer brush holder, an outer brushing part 152, 153 arranged on the outer brush handle 151 and facing inward for brushing the outer wall surface of the container body, and end positioning structures are arranged at both the upper and lower ends of the outer brush handle 151 to fixedly install it on the outer brush holder. By brushing the inner wall surface of the container with the inner wall brush and brushing the outer wall surface of the container with the outer wall brush, the brushing is comprehensive and efficient, greatly shortening the brushing time.

[0069] The brushing device of this solution further includes an inner bottom brush 16 located above the inner wall brush, which is used to clean the bottom of the container and the inner wall surface around the bottom. This further improves the cleaning effect of the brushing device. The inner bottom brush is arranged at the upper end of the inner wall brush. The connection between the inner bottom brush 16 and the inner wall brush is an arc surface or a sloping surface 161 arranged in a dislocation shape on the outer side. The setting of the arc surface or the sloping surface at this connection can be applied to brush the connection between the inner wall and the bottom of a flat-bottomed container, so that the inner side of the container can be fully brushed.

[0070] Moreover, in order to improve the cleaning effect, an elastic member that can elastically push the inner wall brush horizontally outward and / or an elastic structure that elastically pushes the inner wall brush vertically upward are provided between the inner wall brush 14 and the inner brush holder. Through the setting of the elastic member, an outward thrust can be maintained on the wall brush, so that it can keep in contact with the cleaning surface of the container, thereby achieving a better cleaning effect.

[0071] Moreover, an elastic member can also be provided on the outer wall brush. An elastic member that can elastically push the outer wall brush horizontally inward is provided between the outer wall brush and the outer brush holder. To improve the brushing effect of the outer wall.

[0072] Example 1 of the inner wall brush, as shown in Figure 3, its inner brush handle 141 is straight, so as to facilitate brushing the inner wall surface of the container body during rotation. Side blocks 143 are provided on both sides of the upper part of the inner brush handle 141, and a limiting member 144 is provided protruding downward at the lower end. The side blocks 143 and the limiting member 144 enable the inner wall brush 14 to be installed in a limited way. In this example, the side block 143 is manifested as a side convexity, but it can also be set as a side concavity, or directly use the two side edges of the inner wall brush body 141 as the side blocks. The specific connection method can refer to Example 1 of the bracket body.

[0073] Example 2 of the inner wall brush, as shown in Figure 5, the lower end of the inner brush handle 141 is provided with an inclined portion that inclines outward and a bottle mouth brushing portion that extends downward and is connected to the lower end of the inclined portion. It is set according to the structure of the closed-mouth container. A container body with a closed mouth can be, for example, a baby bottle or a heat-insulated cup with a closed mouth. When brushing a baby bottle or a heat-insulated cup with a closed mouth, the inner wall brush surface 142 located at the upper part can be set as bristles, and the inner wall brush surface 343 located at the mouth of the container body can be set as a sponge or a scouring pad.

[0074] The outer wall brush can be provided with lateral outward protrusions to limit the outer wall brush in the left - right direction. However, it can also be without lateral outward protrusions, and instead, lateral inward protrusions similar to the lateral outward protrusion 1212 on the inner vertical frame are provided on the outer vertical frame to perform the same function (the lateral inward protrusion is not shown. Since the inner and outer wall brushes are opposite to each other, the lateral outward protrusion on the inner vertical frame becomes a lateral inward protrusion when borrowed to the outer vertical frame). Similarly, the inner vertical frame can also be without lateral outward protrusions, and instead, lateral inward protrusions similar to the lateral outward protrusion of the outer wall brush are provided on the inner wall brush to limit the inner wall brush in the left - right direction.

[0075] For fixed installation, the method of using lateral inward / outward protrusions plus glue can also be adopted. For example, the inner and outer wall brushes are provided with lateral inward / outward protrusions, and then glue is applied, so that the inner and outer wall brushes can be fixed to the inner and outer vertical frames. At this time, there is no need for limit holes, limit grooves, and lateral outward / inward protrusions on the inner and outer vertical frames.

[0076] In the outer wall brush embodiment, the end - positioning structure is the end - blocking portions 154, 158 extending in the up - down direction along the end face (as shown in Figure 3) or the side - blocking portions 252, 253 extending towards both sides (as shown in Figure 4).

[0077] In the second outer wall brush embodiment, as shown in Figure 5, the outer wall brush surfaces 152 and 153 in the figure are both set as bristles, and the lengths of the bristles are inconsistent. This solution is more suitable for a container body with a certain curvature on the outer wall surface. It can be used in combination with the structure of the second inner wall brush embodiment.

[0078] In the first inner bottom brush embodiment, as shown in Figure 3, the inner bottom brush is connected above the inner brush handle, and the connection part is an arc - shaped section. And the inner bottom brush includes L - shaped connection structures respectively arranged on the two - side inner wall brushes and arranged in a staggered manner. This is mainly to enable the two inner bottom brushes to more fully brush the inner bottom surface of the container body when they cooperate with each other. An inclined surface 164 is provided at the connection part between the inner bottom brush and the inner wall brush. This is mainly because the flat - type inner bottom brush 16 is more suitable for a flat - bottomed container body, and there are internal corners at the inner bottom of the flat - bottomed container body. Therefore, the inclined surfaces 164 with different inclined angles can increase the sufficiency of brushing.

[0079] Second embodiment of the inner bottom brush. As shown in Fig. 5, the inner bottom brush 16 is connected above the inner brush holder through a bottom brush connecting member 3312, and an elastic structure is provided between the inner bottom brush and the bottom brush connecting member. The inner bottom brush 16 includes an inner bottom brush body 361, and inner bottom brush surfaces 362 and 363 provided on the inner bottom brush body 361. The inner bottom brush surface 363 is arranged in an inclined shape, mainly to fit the inner corner in the flat-bottom container body. It should be understood that an inclined brush surface suitable for brushing the inner corner can also be provided at the upper end of the inner wall brush. An installation post 364 is provided below the inner bottom brush body 361, and through the installation post 364, the inner bottom brush 36 can be installed on the upper structure 3312 of the inner brush holder 31: the installation post 364 is inserted downward through the installation holes 3316 and 3315, and then fixed with a snap ring 365. A compression spring 366 can also be sleeved on the installation post 364 to increase the degree of contact between the inner bottom brush surfaces 362 and 363 and the inner bottom surface of the container body.

[0080] The inner wall brush, outer wall brush and inner bottom brush in other embodiments of the container brush device are the same as or similar to the above examples, and will not be elaborated here. In the inner wall brush, outer wall brush and inner bottom brush in the above various embodiments, the brush body can be made of plastic, and the brush surface material can be one of bristles, sponges or scouring pads, or a suitable combination of different types thereof.

[0081] First embodiment of the elastic member: The elastic member includes a compression spring 1243 and a radially positioned limiting protrusion 1242. The limiting protrusion 1242 is provided on the inner wall brush or the outer wall brush, and a limiting hole corresponding to the limiting protrusion 1242 is provided on the inner brush holder or the outer brush holder; as shown in Fig. 19, the elastic member includes a limiting protrusion 1242 provided on the inner brush handle 141, a compression spring 1243 sleeved on the limiting protrusion 1242, and a retaining ring 1244 for positioning the compression spring 1243 on the limiting protrusion 1242. A clamping hole or a strip hole 1213, 1214 for the limiting protrusion 1242 to extend into and fit for installation is provided on the inner brush holder. A limiting protrusion 1242 is provided on the back of the inner wall brush 14, and the limiting protrusion 1242 is used for limiting installation. A compression spring 1243 can be sleeved on the limiting protrusion 1242 to generate a radially outward pushing force on the inner wall brush. A limiting protrusion 1242 is provided on the back of the outer wall brush, and the limiting protrusion 1242 enables the outer wall brush to be installed in a limiting manner. A compression spring 1243 can be sleeved on the limiting protrusion 1242 to generate a radially inward pushing force on the outer wall brush 15.

[0082] Second embodiment of the elastic member. The elastic member includes an elastic sheet 255 and a buckle member 256 for buckling and fixing the elastic sheet 255. Elastic wings that tilt outwards are provided on both sides of the elastic sheet 255. This structure can be provided on the inner brush handle, outer brush handle, inner brush holder, or outer brush holder. As shown in FIG. 4, in this application, taking the example of being provided on the inner brush handle or outer brush handle, a buckle seat 254 is provided on the back of the outer brush handle 251, and a corresponding buckle member 256 is provided. The elastic sheet 255 is clamped on the back of the outer brush handle 251 through the buckle member 256.

[0083] As shown in FIG. 6, it can be regarded as a structural deformation of the second embodiment of the elastic member. Taking the structure provided on the inner brush holder and outer brush holder as an example, by providing a card hole seat 414 (i.e., the buckle seat 254) on the inner brush holder and outer brush holder, corresponding card holes are provided on the elastic member 415, and the leaf spring elastic member 415 is clamped with a card column member 416 (i.e., the buckle member 256). Its structure is simple and the installation is convenient.

[0084] The present invention also provides a simple brushing device applied to a container cleaning machine. Its greatest feature is that the bristles are directly provided on the inner brush holder and outer brush holder. It can also be regarded as directly installing the inner brush handle and the outer brush handle through a connecting seat, regarded as a structure without a bracket (at this time, the inner brush handle and the outer brush handle act as brackets), making the structure of the brushing device simpler and conducive to reducing the manufacturing cost. As shown in FIG. 20, inner bristles 1344 and inner bottom bristles 136 are provided on the inner brush handle 134, outer bristles 1354 are provided on the outer brush handle 135, and the outer brush handle and the inner brush handle are fixedly installed through a base 1332. The specific connection structure can refer to the above-mentioned bracket embodiments.
