Description

[0001] This application is a divisional application of Chinese patent application number 202420857051.5, application date April 23, 2024, and invention name “A connecting rod and a floor scrubber”, the contents of which are incorporated herein by reference. Technical Field

[0002] The utility model relates to the technical field of cleaning equipment, in particular to a connecting rod and a floor scrubber. Background Art

[0003] In the early days, people used brooms, mops, floor wipes, etc. to clean the floor. These tools mainly rely on manual operation to complete the cleaning work. With the advancement of science and technology, people's requirements for floor cleaning tools have gradually increased. The first to appear was the vacuum cleaner, which relies on electricity to generate negative pressure to absorb garbage, dust, etc. on the ground. According to the cleaning methods and the circulation channels of small and large particles of garbage, this type of technology is usually classified as air-dust circulation technology. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains that are firmly attached to the ground. Therefore, a new "water-dust circulation" floor scrubber has appeared. The motor drives the cleaning cylinder to wipe the ground. At the same time, the floor cleaner will also be equipped with a water supply system and a sink to clean the cleaning cylinder, thereby perfectly cleaning the ground.

[0004] The prior art CN220175029U discloses a connecting rod for a floor scrubber, comprising a hollow rod body, an upper connecting assembly and a lower connecting assembly, and also comprising an upper connecting shell and a lower connecting shell, wherein the upper end of the upper connecting shell is fixedly connected to the handle of the floor scrubber, and the lower end of the lower connecting shell is fixedly connected to the mop head of the floor scrubber, and the upper and lower side walls of the rod body are provided with limiting grooves, and when the upper and lower ends of the rod body are respectively inserted into the upper connecting shell and the lower connecting shell, the upper connecting shell and the lower connecting shell respectively extend into the upper and lower ports of the rod body, and the upper connecting assembly, the upper connecting shell, the lower connecting assembly and the lower connecting shell correspond to each other, so that the upper and lower ends of the rod body are respectively firmly connected to the handle of the floor scrubber and the mop head.

[0005] However, the existing "water-dust circulation" floor washer connection rod, whether it is set at the bottom of the water tank or on the body, inevitably occupies a large volume. At the same time, in order to power the floor washer connection rod, it is necessary to pull the floor washer connection rod away to the adapter module for easy power supply. When the user takes the water tank or performs maintenance on the floor washer body, it is inevitable that water will drip onto the adapter module used to power the floor washer connection rod.

[0065] The following further elaborates on the claims of the present utility model in conjunction with specific embodiments and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts also fall within the scope of protection of the present utility model.

[0066] In the present utility model, ordinal numbers such as "first", "second", etc. are only used for distinguishing purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined by "first" and "second" may explicitly or implicitly include at least one of such technical features. In the present utility model, for the convenience of description, there may be quantifier limitations such as "one", "two", "multiple", "at least one", or "several" for limiting technical (structural) features. Among them, the meaning of "multiple" is at least two, that is, it can be two or more; the meaning of "at least one" and "several" is one or more corresponding technical features; the quantifier limitations are only for explaining the specific embodiment or the best implementation mode, and all those that do not conflict with the overall concept of the utility model and the purpose of the utility model should be included, unless it is clearly stated that it must be implemented with the specified quantifier limitations or can achieve the purpose of the utility model.

[0067] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection" shall be understood in a broad sense. For example, it can be either a relatively fixed positional relationship between components or a physically fixed connection between components. It can be either a detachable connection or an integral structure; it can be either a mechanical connection or an electrical signal connection; it can be either directly connected or indirectly connected through an intermediate medium or component; it can be either the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly defined in the specification, when other understandings cannot achieve the corresponding functions or effects, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0068] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model. The present utility model will be further described below with specific embodiments, but it is not a limitation of the present utility model.

[0069] In the first aspect, as Figures 1-13 described, a connecting rod of the present utility model is used for a floor washing machine with a tow head. One end of it is hinged to the tow head 30. The connecting rod includes a hinge body 20, a rod body, and a handle 50. One end of the hinge body 20 is hinged to the tow head 30. The lower end opening of the rod body is detachably connected to the other end of the hinge body. The rod body is detachably connected between the hinge body 20 and the handle 50. A water pump 101 is provided inside the rod body. The hinge body 20, the rod body, and the handle 50 can be quickly docked in sequence. The hinge body 20 and the rod body can achieve the single - time synchronous completion of mechanical docking, circuit line docking (not marked in the drawings), and waterway docking (not marked in the drawings) between the two. The rod body and the handle 50 can achieve the single - time synchronous completion of mechanical docking and circuit line docking between the two.

[0070] In this way, the present utility model reduces the overall volume of the device by connecting and fixing the hinge body, the rod body, and the handle to each other and integrating the power supply, circuit, waterway, and control board inside the rod body, and improves the protection and the convenience of installation and disassembly. At the same time, the connection channel between the rod body and the hinge body accommodates the circuit line and the waterway channel connecting the water pump and the hinge body. Different from the connection between the rod body and the hinge body, the connection channel between the rod body and the handle only accommodates the circuit channel connecting the water pump and the handle. During installation, the user can correctly adapt and install the hinge body, the rod body, and the handle by distinguishing whether the rod body is the end with double - way connection of waterway and circuit with the hinge body or the end with only circuit connection between the rod body and the handle, thus avoiding the problem of incorrect installation between components and improving the installation efficiency of the device.

[0071] In one or some alternative embodiments, as Figure 3 , Figure 4 shown, the hinge body 20 includes a connecting head 20A and a hinge head 20B, and the hinge head 20B is hinged to the towing head 30. The handle 50 is away from the towing head 30 and has a clamping portion 50A and a gripping portion 50B.

[0072] In one or some alternative embodiments, as Figure 3 , Figure 4 shown, the rod body includes a lower rod 10 and an upper rod 40 which are butted against each other; when the lower rod 10 and the upper rod 40 are butted, at least the circuit lines built in the lower rod 10 and the upper rod 40 are synchronously butted; the lower rod 10 and the upper rod 40 are hollow inside, and the rod body further includes an inner bracket 100A with both ends open and disposed inside the lower rod 10 or the upper rod 40; one end of the inner bracket 100A is provided with a lower port 100A1, and the lower port 100A1 faces the connecting head 20A of the hinge body 20; the other end of the inner bracket 100A is provided with an upper port 100A2, and the upper port 100A2 is electrically connected to the handle 50.

[0073] It should be noted that there is no limitation here on whether the inner bracket 100A is installed inside the lower rod 10 or the upper rod 40. Of course, the inner bracket 100A can also be installed between the lower rod 10 and the upper rod 40. As long as the technical solution in which the inner bracket 100A is installed inside the rod body is within the protection scope of this application. More importantly, there is no limitation here on the specific number of the inner brackets 100A. The inner brackets 100A can be set to at least 2, and at least one of the inner brackets 100A can be respectively disposed inside the lower rod 10 and the upper rod 40. The technical solutions in which at least 2 inner brackets 100A are installed inside the rod body are within the protection scope of this application.

[0074] In this way, the inner bracket is adapted to the hollow shape inside the lower rod or the upper rod, so that when the floor washer works, the inner bracket placed inside the lower rod or the upper rod will not have problems of sliding and falling off; the inner bracket arranged inside the lower rod or the upper rod serves as a bearing and connecting unit for the components inside the rod body to realize the integrated installation of the water circuit, the circuit and the power supply inside the rod body; on the other hand, since the lower rod and the upper rod are hollow inside, the support of the inner bracket placed inside the lower rod and / or the upper rod on the inner walls of the lower rod and the upper rod can also increase the structural strength and rigidity of the lower rod and / or the upper rod, thereby further increasing the rigidity of the rod body while reducing the overall weight of the rod body.

[0075] In one or some alternative embodiments, as Figures 3 to 5 , Figure 7As shown, a water pump 101 is provided on the inner support 100A, and the water pump 101 is disposed on one side of the inner support 100A close to the lower port 100A1; the water pump 101 is provided with a water outlet 101a and a water inlet 101b, and both the water outlet 101a and the water inlet 101b are arranged in the direction of the hinge body 20. A water outlet pipe and a water inlet pipe are respectively arranged at the water outlet 101a and the water inlet 101b, and the water outlet pipe and the water inlet pipe respectively pass through the rod body and communicate with the connection head 20A of the hinge body 20 to form a water channel for communicating the rod body and the hinge body 20.

[0076] In this way, by providing a water pump on the inner support, and arranging the water outlet and the water inlet of the water pump in the direction of the hinge body, it is convenient to respectively pass the water outlet pipe, the water inlet pipe connecting the water outlet, the water inlet and the hinge body through the rod body and communicate with the connection head of the hinge body, which can make the length of the water pipeline inside the rod body the shortest and the connection more convenient. At the same time, a single docking of the rod body and the hinge body can realize the quick docking of the water channel for communicating the rod body and the hinge body.

[0077] In one or some alternative embodiments, as Figures 3 to 5 shown, a battery pack 120 and a control board 110 are further provided on the inner support 100A. The battery pack 120 is disposed on one side of the inner support 100A close to the upper port 100A2; the control board 110 is threadedly connected to a fixed nut column (not shown in the drawing) of the inner support 100A. The control board 110 is provided with an electrode plate group (not shown in the drawing), and the electrode plate group clamps the battery pack 120. The inner support 100A and the control board 110 jointly fix the battery pack 120 to improve the integration degree of the inner support 100A; in a preferred embodiment, the battery 120 is placed as a power source inside the rod body. By providing the inner support 100A, while facilitating the disassembly and installation of the rod body, it is also convenient for the replacement and maintenance of the battery 120.

[0078] Furthermore, the battery pack 120 includes two or more batteries connected in series first and then in parallel. The control board 110 is electrically connected to the water pump 101 and a drive motor (not shown in the drawing) for driving the cleaning roller to rotate inside the drag head. The control board 110 is electrically connected to the charging port (not shown in the drawing) of the handle 50. When the control board 110 controls the water pump 101 and the drive motor to work, the battery pack 120 is in a working condition of discharging outward. When an external power adapter is electrically connected to the charging port, the external power adapter charges the battery pack 120 through the control board 110.

[0079] Thus, a battery pack and a control board are arranged on the inner support. Inside the rod body, the control board is electrically connected to the water pump and the drive motor that drives the cleaning roller to rotate in the towing head. The control board is provided with an electrode sheet group for clamping the battery pack, which can conveniently connect and fix the hinge body, the rod body and the handle to each other, and integrate and install the power supply, the circuit and the control board inside the rod body, reducing the overall volume of the device and improving the protection performance and the convenience of installation and disassembly. At the same time, a single docking of the rod body and the hinge body can achieve a quick docking of the circuit lines communicating between the rod body and the hinge body, and a single docking of the rod body and the handle can achieve a quick docking of the circuit lines communicating between the rod body and the handle.

[0080] In one or some alternative embodiments, as Figures 3 to 5 shown, the control board 110 is electrically connected to the lower terminal wire harness 105. The end of the lower terminal wire harness 105 is provided with a lower docking terminal 104. The lower docking terminal 104 passes through the lower port 100A1 and the rod body in sequence and is electrically connected to the connection head 20A of the hinge body 20.

[0081] In one or some alternative embodiments, as Figures 3 to 5 shown, the control board 110 is also electrically connected to the upper terminal wire harness 106. The end of the upper terminal wire harness 106 is provided with an upper docking terminal 107. The upper docking terminal 107 passes through the upper port 100A2 and the rod body in sequence and is electrically connected to the handle 50.

[0082] Thus, a control board is arranged on the inner support. Inside the rod body, the control board is electrically connected outside the rod body. The control board is electrically connected to the lower terminal wire harness, and the lower terminal wire harness passes through the lower port and is electrically connected to the hinge body. The control board is electrically connected to the upper terminal wire harness, and the upper terminal wire harness passes through the upper port and is electrically connected to the handle. While conveniently and quickly docking the hinge body, the rod body and the handle to each other, a single docking of the rod body and the hinge body can achieve a quick docking of the circuit lines communicating between the rod body and the hinge body, and a single docking of the rod body and the handle can achieve a quick docking of the circuit lines communicating between the rod body and the handle.

[0083] In one or some alternative embodiments, as Figures 3 to 5As shown, a flow sensor 103 is also provided on the inner bracket 100A, and the flow sensor 103 is arranged between the water pump 101 and the lower port 100A1. The flow sensor 103 is connected to the water outlet 101a and the water outlet pipe to measure the flow in the water outlet 101a. Further, the flow sensor 103 is also electrically connected to the control board 110, and the flow sensor 103 transmits the real-time flow data of the water outlet 101a of the water pump 101 back to the control board 110, and the control board 110 can adjust the control strategy of the water pump 101 in real time according to the received flow data.

[0084] In this way, after the flow sensor is arranged in the rod body, the control board can adjust the control strategy of the water pump in real time according to the flow data of the water pump, so as to make the floor scrubber more energy-saving and efficient.

[0085] In one or some alternative embodiments, Figures 3 to 5 As shown, the control board 110 is also provided with at least one temperature sensor 111, which senses the temperature of the control board 110 and the battery pack 20, and feeds back to a display unit (not shown in the drawing) provided on the surface of the handle 50 through a signal connection.

[0086] In this way, the control panel is also provided with at least one temperature sensor, which allows the control panel to obtain the temperature of the battery pack and the control panel in real time, and can use the temperature data measured in real time by the control panel to timely adjust the control strategy of the water pump and the drive motor, so as to make the floor scrubber more energy-saving and efficient.

[0087] In one or some alternative embodiments, Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 11 As shown, the hinge body 20 includes a connecting head 20A and a hinge head 20B. A connecting terminal (not marked in the drawings) is provided at the end of the connecting head 20A of the hinge body 20. Connecting terminals, water inlet interface and water outlet interface are provided inside the connecting terminal. The lower rod lower docking sleeve 100B is sleeved on the connecting head 20A of the hinge body 20. The connecting end of the connecting head 20A extends into the lower rod lower terminal seat 100B1 of the lower rod lower docking sleeve 100B. The lower rod lower terminal seat 100B1 is adapted and fixed to the lower port 100A1 of the inner bracket 100A.

[0088] In this way, the rod body and the hinge body 20 are detachably connected to each other through the lower rod lower docking sleeve 100B, making the connection between the hinge body 20 and the rod body more stable and improving the structural stability. At the same time, through the single quick docking of the rod body and the hinge body 20, the mechanical docking, electrical connection docking, and waterway connection docking between the rod body and the hinge body 20 can be completed, which is efficient and convenient.

[0089] In one or some alternative embodiments, as Figures 1 to 3 shown, the connecting rod is also hinged with a towing head 30 at the hinge head 20B of the hinge body 20. The water pump 101 in the rod body is controlled by the handle 50 to supply water to the towing head 30, and the battery pack 120 in the rod body is controlled by the handle 50 to supply power to the water pump 101 and the drive motor, so as to perform cleaning work.

[0090] In this application, the mechanical docking between the rod body and the hinge body 20 can simultaneously realize the simultaneous docking of the circuit line and the waterway channel between the rod body and the hinge body 20; different from the mechanical docking between the rod body and the handle 50, only the simultaneous docking of the circuit line between the rod body and the handle 50 can be realized. Coupled with the differences in the corresponding docking interfaces at the two mechanical docking locations, each docking interface has already been anti-fooled, so the user will not make mistakes in docking the hinge body 20, the rod body, and the handle 50, thus avoiding the problem of incorrect installation between components and improving the installation efficiency of the device. Moreover, when an electrical connection failure occurs, if the control board 110 reports a connection failure of the water pump 101 or the drive motor, then the failure may only occur in the electrical connection failure of the circuit line between the rod body and the hinge body 20. If it is a display failure of the display device of the handle 50, the electrical connection failure can only occur in the electrical connection failure of the circuit line between the rod body and the handle 50. If the control board 110 reports a low flow rate of the water pump 101, in addition to the possible failure of the water pump 101 itself, the connection of the waterway channel between the rod body and the hinge body 20 may also leak.

The water pump 101 is arranged on one side of the inner bracket 100A close to the lower port 100A1; the water pump 101 is provided with a water outlet 101a and a water inlet 101b. A water outlet pipe and a water inlet pipe are respectively arranged at the water outlet 101a and the water inlet 101b. The water outlet pipe and the water inlet pipe respectively pass through the lower rod lower docking sleeve 100B and are communicated with the connecting head 20A of the hinge body 20 to form a water channel for communicating the lower rod 10 and the hinge body 20.

[0098] Further, as Figures 3 to 5As shown, a battery pack 120 and a control board 110 are further provided on the inner support 100A. The battery pack 120 is arranged on one side of the inner support 100A close to the upper port 100A2; the control board 110 is threadedly connected to the fixed nut column of the inner support 100A. An electrode sheet group is provided on the control board 110, and the electrode sheet group clamps the battery pack 120. The inner support 100A and the control board 110 jointly fix the battery pack 120.

[0099] Further, as Figures 3 to 5 、 Figures 7 to 11 shown, the control board 110 is electrically connected to the lower terminal wire harness 105. A lower docking terminal 104 is provided at the end of the lower terminal wire harness 105.

This docking can simultaneously achieve the mechanical docking and electrical connection docking of the lower rod 10 and the upper rod 40.

[0103] Further, as Figure 8 、 Figure 10 、 Figure 12 、 Figure 13As shown, there is also a groove on the outer side wall where the upper rod lower docking sleeve 400B is sleeved with the lower rod upper docking sleeve 100C. An elastically retractable elastic buckle 400B1 is arranged in the groove. The elastic buckle 400B1 compresses the spring 400B2 in the groove so that the elastic buckle 400B1 always maintains an elastic abutting force outward to abut against the inner wall of the lower rod upper docking sleeve 100C sleeve. Correspondingly, a clamping groove is arranged on the inner wall of the lower rod upper docking sleeve 100C sleeve to accommodate the clamping end of the elastic buckle 400B1. When the upper rod lower docking sleeve 400B is sleeved with the lower rod upper docking sleeve 100C in place, the clamping end extends into the clamping groove, further improving the stability of the sleeve connection between the upper rod lower docking sleeve 400B and the lower rod upper docking sleeve 100C. When it is necessary to separate the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C, a tool needs to be borrowed first to press the clamping end of the elastic buckle 400B1 from the corresponding hole (not marked in the attached drawing) of the upper rod housing 400. When the clamping end exits the clamping groove, pull the lower rod 10 and the upper rod 40 forcefully to separate the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C.

[0104] In the above Embodiment 1, since the inner bracket 100A is installed in the cavity of the lower rod housing 100, a water pump 101, a flow sensor 103, a battery pack 120, and a control board 110 are installed on the inner bracket 100A. There are no components configured in the cavity of the upper rod 40 except that the lower end terminal wire harness 405 of the upper rod passes through. The weight of the lower rod 10 will exceed the weight of the upper rod 40, and the center of the rod body will also be more downward. When the user pushes and pulls the connecting rod by holding the handle 50, it will be felt more convenient. In this embodiment, only the mechanical docking of the lower rod 10 and the hinge body 20 realizes the simultaneous docking of the circuit line and the water channel between the two, while the mechanical docking of the lower rod 10 and the upper rod 40, and the mechanical docking of the upper rod and the handle only realize the simultaneous docking of the corresponding circuit lines between the two. Coupled with the differences in the corresponding docking interfaces at the two mechanical docking locations, each docking interface has been anti-fooling processed, so the user will not make mistakes in docking the hinge body 20, the rod body, and the handle 50, thus avoiding the problem of incorrect installation between components and improving the installation efficiency of the device.

[0105] Embodiment 2

[0106] Compared with the first embodiment described above, in the solution of this embodiment, the inner bracket 100A is arranged inside the upper rod 40; there will be no problem of the inner bracket 100A sliding and falling off inside the upper rod 40; the inner bracket 100A arranged inside the upper rod 40 serves as a bearing and connection unit for the components inside the upper rod 40 to realize the integrated installation of the water circuit, circuit and power supply inside the upper rod 40; the support of the inner bracket 100A on the inner wall of the upper rod 40 can also increase the structural strength and rigidity of the upper rod 40. Correspondingly, the electrical connection harness and the water circuit connection pipeline need to pass through the cavity inside the entire lower rod 10 from the inner bracket 100A in the cavity of the upper rod 40. Correspondingly, the circuit harness and the water pipeline connecting the hinge body 20 to the rod body will be correspondingly longer. Docking components for simultaneous electrical and water circuit docking are configured at both ends of the lower rod 10, and a docking component for simultaneous electrical and water circuit docking is configured at the lower end of the upper rod 40. Other technical details are exactly the same as those of the first embodiment and will not be elaborated here.

[0107] In this embodiment, the center of gravity of the rod body is more upward relative to the first embodiment. When the user holds the handle 50 and pushes and pulls the drag head 30, the overall experience will be somewhat different from that of the first embodiment, but the power supply, circuit, water circuit and control board are all integrally installed inside the rod body, reducing the overall volume of the device and improving the protection and the convenience of installation and disassembly.

[0108] Embodiment Three

[0109] Compared with the first and second embodiments described above, in the solution of this embodiment, the inner bracket 100A is arranged between the lower rod 10 and the upper rod 40; there will be no problem of the inner bracket 100A sliding and falling off inside the lower rod 10 and the upper rod 40; the inner bracket 100A arranged inside the lower rod 10 and the upper rod 40 serves as a bearing and connection unit for the components inside the lower rod 10 and the upper rod 40 to realize the integrated installation of the water circuit, circuit and power supply inside the lower rod 10 and the upper rod 40; the support of the inner bracket 100A on the inner walls of the lower rod 10 and the upper rod 40 can also increase the structural strength and rigidity of the lower rod 10 and the upper rod 40. Since the length of the inner bracket 100A is relatively long, the length dimension of the cooperation between the inner bracket 100A and the lower rod 10 and the upper rod 40 is longer than the cooperation dimension between the lower rod 10 and the upper rod 40 in the first and second embodiments, and the stability of the cooperation between the lower rod 10 and the upper rod 40 through the inner bracket 100A is higher. Other technical details are exactly the same as those of the first and second embodiments described above and will not be elaborated here.

[0110] Embodiment Four

[0111] Compared with the first, second, and third embodiments described above, in the solution of this embodiment, the number of the inner brackets 100A is more than 2. When the number of the inner brackets 100A is set to an odd number, the third embodiment described above can be referred to; when the number of the inner brackets 100A is set to an even number, the first or second embodiment described above can be referred to; other technical details are exactly the same as those of the first, second, and third embodiments described above, and will not be elaborated here.

[0112] Embodiment Five

[0113] In a second aspect, the present utility model provides an embodiment of a floor washer, which includes a mop head 30 and the connecting rod described in the first aspect. By connecting and fixing the hinge body 20, the rod body, and the handle 50 to each other, and integrating and installing the power supply, circuit, waterway, and control board inside the rod body, the overall volume of the device is reduced, and the protection and the convenience of installation and disassembly are improved; at the same time, the connection channels between the rod body and the hinge body accommodate the circuit lines and waterway channels connecting the water pump and the hinge body; different from the connection between the rod body and the hinge body, only the circuit channel connecting the water pump and the handle is accommodated in the connection channel between the rod body and the handle. During installation, the user can correctly adapt and install the hinge body, the rod body, and the handle by distinguishing whether the rod body is the end connected to the waterway and the circuit of the hinge body or the end where the rod body is only connected to the circuit of the handle, thereby avoiding the problem of incorrect installation between each component and improving the installation efficiency of the device.

[0114] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement or combination on some structures (technical features) in one or more embodiments. These modifications, replacements, or combinations do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model, unless it is clearly excluded in the embodiments that the structures (technical features) in different embodiments can be replaced or combined, or this replacement or combination is contrary to the overall concept of the utility model.
