Description

Toilet bowl

Technical Field

The utility model relates to a toilet, in particular to a toilet with a urine detection system.

Background

Currently, urine testing methods can be broadly divided into two types: a urine detector used in traditional hospitals is used, a patient holds a transparent plastic cup to go to a toilet to take urine, then the urine is poured into a measuring cup and then sent back to a detection window of the hospital, after the test tubes in the detection window are full, the urine detector is put into a machine to perform unified detection, and finally a detection result is given; the other is to take out the urine detector by means of the household urine detector, take one end of the urine detector to take urine, detect the urine by using a photoelectric detection module after the urine is taken out, display the result, and finally wash the urine detector with water to finish single urine detection.

Along with the continuous development of the intelligent toilet, the integrated urine detection function is one of the development directions of the intelligent toilet. The toilet bowl can collect, detect, analyze and the like urine of a user, and related equipment is flushed after detection is finished, so that cross infection is avoided, and the accuracy of subsequent detection is improved.

However, the current toilet with urine detection function has the following problems: the urine collecting module in the toilet is complex in structure, and the cleaning procedure of the cleaning module is complex, so that the toilet is inconvenient to install integrally, and the failure rate is high. In addition, water from the toilet tank can also carry some bacteria that are resident in the tank when the urine test device is cleaned, thereby affecting the accuracy of the urine test result. In addition, although the user hopes that the toilet can realize the urine detection function, the space occupied by the toilet is required to be small, and the functions cannot be mutually influenced.

Therefore, there is always a need in the field of toilets to be able to implement the urine test function while keeping the overall structure uncomplicated, in particular the cleaning procedure uncomplicated. In addition, there is a need to keep the impact on urine detection accuracy as small as possible. In addition, there is also a need to make the toilet occupy a small space, and the various cleaning functions do not interfere with each other.

Disclosure of Invention

The present utility model provides a toilet bowl, which may include: a base body with a dirt receiving groove; a water inlet pipe through which water from a water supply source flows into the toilet bowl; a flushing line, which is in selective fluid communication with the water inlet line for flushing the dirt receiving tank; a urine detection system capable of being in selective fluid communication with the water inlet conduit, the urine detection system may include a urine detection configuration in which the urine detection system is capable of sampling and detecting urine flowing into the dirt receiving tank, and a cleaning configuration in which the urine detection system is capable of cleaning with water from the water inlet conduit.

By having water from the water supply source flow directly into the toilet bowl via the water inlet line for flushing or cleaning the urine test system, the probability that the cleaning water for the urine test may contain dirt is reduced while keeping the toilet bowl small in occupied space and relatively simple in structure, thereby facilitating improvement of the urine test accuracy.

Preferably, the toilet may include: the sampling device can be arranged in the sewage containing tank and is used for sampling urine; a liquid collection device in selective fluid communication with the sampling device to collect sampled urine therein; the first washing line may be arranged between the liquid collecting device and the water inlet line such that in the washing configuration water from the water inlet line can flow into the liquid collecting device and thereby the sampling device via the first washing line for washing both.

The liquid collecting device and the sampling device are directly cleaned from the water inlet pipeline by utilizing the cleaning pipeline, so that the efficiency of cleaning dirt in the liquid collecting device and the sampling device can be improved.

Advantageously, the urine detection system may further comprise: the detection device is used for detecting urine collected in the liquid collecting device; the second washing line may be arranged between the detection device and the water inlet line such that in the washing configuration water from the water inlet line can flow into the detection device via the second washing line for washing thereof.

Under the condition that the detection device is arranged, the second cleaning pipeline can enable the water from the water inlet pipeline to directly clean the detection device instead of cleaning the detection device through other devices, so that the cleaning efficiency is improved, and the higher cleanliness of the detection device is ensured. By means of a second washing line, which is arranged separately from the first washing line, various control strategies for washing the urine detection system can be provided.

In particular, in the cleaning configuration, the detection device can be in fluid communication with the liquid collection device such that water flows into the liquid collection device via the detection device.

Through the fluid communication between the detection device and the liquid collecting device in the cleaning configuration, the liquid collecting device can be cleaned by water flowing through the detection device, so that the utilization rate of the cleaning water is improved.

Preferably, the toilet bowl may further comprise a first valve device, which may be configured to be switchable between a first operating position, in which water from the water inlet line flows into the flushing line, and a second operating position, in which water flows into the urine detection system.

By means of the first valve device, it is possible to switch between flushing the toilet bowl and cleaning the urine detection system, thereby improving efficiency and simplifying construction.

Advantageously, the toilet bowl may further comprise an air pump configured to supply air to the sampling device to facilitate cleaning thereof.

By supplying the sampling device with gas, dirt that may remain or accumulate within the sampling device may be agitated so that it may flow out of the sampling device with the gas flow, or at least may flow out of the sampling device with the water flow more easily in a cleaning configuration due to loosening of the dirt.

Preferably, the toilet bowl may further comprise a vacuum pump connected to the liquid collecting device, and the vacuum pump may be configured to drain the waste liquid from the liquid collecting device to the waste receiving tank.

By means of the vacuum pump, the waste liquid can be discharged from the liquid collecting device more easily and efficiently, so that the possibility of dirt accumulating in the urine detection system is reduced.

In addition, the toilet bowl may further comprise a toilet cover, which may include an outlet conduit for toilet cleaning by a user, and the urine detection system may further comprise a second valve device, which may be configured to switch between a third operating position, in which the water inlet conduit may be in fluid communication with at least one of the first and second cleaning conduits, and a fourth operating position, in which the water inlet conduit may be in fluid communication with the outlet conduit.

The second valve device can enable the water from the water inlet pipeline to directly flow into the toilet cover, thereby playing a cleaning role after the user uses the toilet. The cleaning water can be separated from one water for flushing the toilet and one water for cleaning the urine detection system, so that the aim of sanitary isolation is fulfilled, and different cleaning requirements are met.

In addition, the toilet may further include a third valve device, which may be configured to regulate water pressure and flow rate flowing into at least one of the first washing line, the second washing line, and the water outlet line. Thereby, it is possible to avoid that the excessive water flow impinges on devices communicating with the first or second washing line, such as liquid collecting devices, sampling devices, and thus that they reduce the service life or are damaged due to excessive water pressure. Meanwhile, the water outlet flexibility of the water outlet pipeline of the toilet cover can be reduced by controlling the water pressure and the flow of the cleaning water flowing into the toilet cover.

In particular, the toilet may further include: a water supply monitoring device, which may be configured to monitor a physical parameter of water from a water supply source; a rinse valve, the rinse valve being in fluid communication with the rinse line such that water for rinsing flows through the rinse valve to the dirt receiving tank, and a hold open time of the rinse valve is variable based on the physical parameter. For example, when the pressure or flow of water provided by the water supply monitoring device is not high, the flush valve may be extended to remain open to achieve a desired amount of flush water in an effective flush cycle, thereby increasing the flushing force to the dirt holding tank.

Detailed Description

In the present utility model, the term "toilet bowl" refers to an entire cleaning system for a toilet, including, for example, a seat body having a dirt receiving groove, a toilet bowl cover, various pipes, wires, connectors, fittings, and the like. It is understood that the toilet of the present utility model is not limited in type, and intelligent toilets, direct flush toilets, siphon toilets, low profile toilets, and various conventional toilets are within the scope of the present utility model.

In the present utility model, the term "system" refers to a collection of elements in various forms including physical devices, electrical circuits, fluid circuits, controllers and the like. Furthermore, the term "conduit" refers to an element for fluid delivery that is not limited in its specific shape and size (e.g., is not necessarily circular in cross-section) nor does it exclude that other fluid components may be provided on the conduit.

In the present disclosure, the term "selective fluid communication" means that fluid communication may or may not be provided (e.g., as may be provided according to different control strategies or other requirements), but has the capability of enabling fluid communication.

It is to be understood that in the present utility model, the terms "first," "second," "third," etc. merely denote various separate entities (not a single entity, unless otherwise indicated), but rather denote a priority or importance of their own.

The toilet 100 of the present utility model includes a seat (or bowl) made of, for example, ceramic or resin. A toilet cover 114 of the toilet may be directly seated on the top surface of the seat of the toilet 100. According to the present utility model, the toilet cover 114 may be a conventional toilet cover (i.e., a toilet cover having only a function of covering the dirt receiving groove 112 of the toilet bowl) or an electronic toilet cover (or "intelligent toilet cover"), wherein the electronic toilet cover may provide various different types of functions such as a toilet cleaning function, a drying function, a sterilizing function, a heating function, etc., according to the user's needs.

The housing has a dirt receiving slot 112 (or dirt receiving pool), the dirt receiving slot 112 being sized and shaped to facilitate a user's toilet. The dirt receiving tank 112 generally includes a dirt receiving surface and a drain 113 at the bottom of the tank. It will be appreciated that the dirt receiving surface (also referred to as the dirt receiving tank inner wall, dirt receiving surface) extends downwardly from the top of the dirt receiving tank 112 and merges into the drain 113. The sewage flows from the sewage outlet 113 to the sewage pipe, and thus flows out of the seat of the toilet 100.

The toilet 100 of the present utility model includes a water inlet pipe 120, and water flows into the toilet 100 through the water inlet pipe 120. The water flowing into the water inlet line 120 comes from an external water supply source 200, such as a mains water network (e.g., a water network disposed within a user's home building) or other municipal water.

For this, the water inlet pipe 120 may be directly connected to the water supply source 200, but the connection structure or connection manner of the water inlet pipe 120 to the water supply source 200 is not limited, for example, the water inlet pipe 120 may extend only partially or entirely inside the body of the toilet 100. In other words, the water inlet line 120 according to the utility model may not exclude that it extends outside the seat of the toilet 100, for example to a water inlet interface provided on a wall.

Advantageously, the toilet 100 may further comprise a water supply monitoring device 180, the water supply monitoring device 180 being configured to monitor a physical parameter of the water from the water supply source 200 or a water flow parameter of the water inlet end of the toilet 100. The physical parameter may be the flow rate of water, the pressure of water, etc. Preferably, the water supply monitoring device 180 may be in the form of one or more sensors, for example, the water supply monitoring device 180 may be configured as a flow monitor or a water pressure monitor.

The toilet 100 according to the present utility model can achieve the flushing of the sewage receiving tank 112, and thus the toilet 100 includes the flushing line 130. In an advantageous embodiment, the toilet 100 may implement a rim flush and a bottom flush, respectively. To this end, the flushing line 130 may comprise a loop flushing line for loop flushing the dirt receiving tank 112, mainly the dirt receiving surface thereof. In addition, the flushing line 130 may also comprise an undershoot line for undershooting the dirt receiving tank 112, mainly the bottom thereof. It will be appreciated that the ring and undershoot lines may have a portion that is coextensive but may also be two lines that are completely independent of each other and separate.

Advantageously, the toilet 100 may also include a flush valve 132 (or drain valve). The flush valve 132 may be an electrically controlled valve, such as an electrically controlled hydraulic valve, i.e. the flush valve 132 may be opened or closed in an electrically controlled manner. It will be appreciated that when the flush valve 132 is open, water for flushing flows through the flush valve 132 into the rim flush line and/or the bottom flush line and then through these lines into the dirt receiving tank 112 of the housing.

Preferably, the toilet 100 of the present utility model may not be provided with a booster pump. For example, when the pressure or flow of water provided by the water supply monitoring device 180 is not high, the flush valve 132 may be extended for an extended period of time (the length of time extended may also be preset) to achieve a desired amount of flush water in an effective flush cycle, thereby increasing the flushing force to the dirt holding tank 112. The position of the water supply monitoring device 180, preferably a flow monitor or a water pressure monitor, in the toilet 100 is not limited, and may be arranged on the flush valve 132, i.e. integrated to the flush valve 132, or on a line between the flush valve 132 and the water inlet line 120, etc.

The toilet 100 of the present utility model also includes a urine detection system for performing one or more of the following functions: the urine of the user is sampled, collected, transferred, inspected, analyzed, etc. The urine detection system includes at least two configurations. Herein, the term "configuration" refers to a set of states or positions (of components or devices) or the like that the system presents.

The first configuration is a urine testing configuration in which the urine testing system is able to sample and test urine flowing into the dirt receiving tank 112. Herein, the term "detecting" may include analyzing urine, giving detection results, etc., but may not include these functions, but may merely be measuring a specified index in urine, such as urine protein.

The second configuration is a cleaning configuration in which the urine test system can clean its own system (various devices, components, piping, etc., which may include the urine test system) with water from the water inlet line 120 of the toilet 100 (i.e., water directly from the water supply source 200)

The toilet 100 of the present utility model can supply water from the water supply source 200 to the flush line 130 to flush the dirt receiving tank 112 of the toilet 100 (whether in a rim wash, a bottom wash, or both), as well as to the urine detection system for cleaning. The water supply to the flush line 130 and the urine test system is preferably not simultaneous, but it is not precluded that the supplies can be simultaneous.

In a preferred embodiment, the toilet 100 may comprise a first valve device 151, which first valve device 151 is typically arranged downstream of the water inlet line 120. Herein, the term "downstream" means farther from the water supply source 200 as seen in the direction of the water flowing into the toilet 100. The first valve device 151 may be, for example, a three-way valve, in particular a three-way angle valve, but may also be a valve of other construction. The form of actuation of the first valve device 151 is not limited, and may be, for example, a solenoid valve.

The first valve device 151 may comprise at least two operating positions, i.e. may be switchable between at least two operating positions. In the first operating position, water from the water inlet line 120 may flow into the flush line 130 but not into the urine test system, and in the second operating position, water from the water inlet line 120 may flow into the urine test system but not into the flush line 130. Of course, the utility model does not exclude that the first valve means 151 may also comprise a third operating position, in which water from the water inlet line 120 may flow into both the flushing line 130 and the urine detection system, but this is not preferred.

The urine detection system according to the utility model may comprise sampling means 141 arranged within the receiving tank 112, in particular on the receiving surface (see e.g. fig. 3), for sampling urine of a user. The urine detection system is also preferably equipped with a sensor that can detect the flow of urine into the dirt receiving tank 112. More preferably, the urine detection system can control the sampling device 141 to sample urine at the appropriate timing. For example, sampling device 141 may begin sampling urine when the sensor detects that urine has flowed into the receiving tank 112 for a predetermined period of time (e.g., three seconds) has elapsed. Thus, the sampling device 141 can sample the middle section of urine, thereby improving the accuracy of urine testing (since the initial section of urine may cause a large error in the test results due to the verification of the urethra).

The urine detection system may also include a liquid collection device 142, which liquid collection device 142 may be in selective fluid communication with the sampling device 141 to collect sampled urine therein. In the present utility model, although some urine may be left in the sampling device 141, its primary function is not to hold urine therein, but only to take liquid. In contrast, the liquid collection device 142 is primarily used to retain urine therein for later testing by a testing device 143 (if any), such as sampling testing.

To clean the liquid collection device 142 and the sampling device 141, in a cleaning configuration of the urine inspection system, water from the water inlet line 120 may flow into the liquid collection device 142 and through the liquid collection device 142 to the sampling device 141. Subsequently, the waste liquid (i.e., the water that has cleaned the liquid collection device 142 and the sampling device 141) may be discharged via the liquid collection device 142, for example directly into the dirt receiving tank 112 or the drain 113 at the tank bottom, although it is also contemplated that other lines or devices may be flowed into and out of the toilet 100. Of course, the present utility model does not exclude water from the liquid collection device 142 to the sampling device 141 and directly drain the waste liquid from the sampling device 141, but this is not preferred because the sampling device 141 is typically not in communication with the outside (e.g., not to the sink 112) without sampling to avoid introducing unnecessary bacteria and the like.

The urine detection system may comprise a first washing line 144, which first washing line 144 is arranged between the liquid collecting device 142 and the water inlet line 120, such that in the washing configuration water from the water inlet line 120 can flow via the first washing line 144 into the liquid collecting device 142 and thereby the sampling device 141, thereby washing both. Of course, the present utility model does not exclude that in the cleaning configuration of the urine inspection system, water from the water inlet line 120 flows directly into the liquid collection device 142, but this is not preferred because it does not facilitate flexibility in the placement of the various devices within the toilet 100.

In a preferred embodiment, the urine detection system may further comprise a detection device 143 for detecting urine collected and held in the liquid collection device 142. To this end, the detection device 143 may be in selective fluid communication with the liquid collection device 142. For example, when testing is desired, the testing device 143, such as through a sampling needle, transfers a small portion of urine (e.g., one or two drops of urine) from the fluid collection device 142 therein. The structure of the detecting device 143 is not an important element of the present utility model, and thus is not described herein.

In the cleaning configuration, the detection device 143 may be specifically cleaned. For this purpose, water from the water inlet line 120 may flow directly into the detection device 143. In a preferred embodiment, the urine detection system may comprise a second washing line 145, which second washing line 145 is arranged between the detection device 143 and the water inlet line 120, such that in the washing configuration water from the water inlet line 120 can flow into the detection device 143 via the second washing line 145 for washing thereof, see for example fig. 1.

In some embodiments, the water, i.e., the waste liquid, washed by the detection device 143 may be separately discharged into the toilet 100 without flowing to the liquid collecting device 142. In other embodiments, waste fluid from the detection device 143 may also flow into the collection device 142, thereby being re-discharged via the collection device 142. In other words, in this case, in the urine testing configuration, urine may flow from the liquid collection device 142 to the detection device 143, while in the washing configuration, waste liquid may flow from the detection device 143 to the liquid collection device 142. It will be appreciated that the path of waste liquid from the detection means 143 to the collection means 142 may not be the same path as the path of urine from the collection means 142 to the detection means 143, for example, only a detection needle is used to sample from the collection means 142 during detection, but the waste liquid may be caused to flow from the detection means 143 directly to the collection means 142 via another line during washing. If waste liquid flows from the detection device 143 into the collection device 142, clean water (i.e., water from the water inlet line 120) should also be allowed to flush the collection device 142 and the sampling device 141 (e.g., via the first purge line 144).

As previously described, the intelligent toilet 100 may further include an electronic toilet lid or intelligent toilet lid. Such a toilet cover 114 includes a water outlet line for flushing after a user has used a toilet. The specific structure of the water outlet pipeline is not an important point of the present utility model, and is not described herein.

In addition, the urine test system of the present utility model may further include a second valve device 152, and the second valve device 152 is, for example, a two-position three-way valve, but is not limited thereto. The second valve device 152 may be configured to be switchable between a third operating position in which the water inlet line 120 is in fluid communication with at least one of the first and second purge lines 144, 145, preferably the water inlet line 120 is in fluid communication with both purge lines, and a fourth operating position in which the water inlet line 120 is in fluid communication with the water outlet line of the toilet cover (not shown), but may also include other more positions.

In the present utility model, the first and second wash pipes 144 and 145 may be simultaneously supplied with water, but either may be supplied with water alone (i.e., water from the water inlet pipe). If either is to be supplied separately, other fluid means, such as other valves or fluid connectors, etc., may also be included between the second valve means 152 and the first and second purge lines 144 and 145. It is worth noting that the flow direction of the water for cleaning, not shown in fig. 1, is also within the scope of the present utility model, i.e. the direction of the water flow is not exhaustive in fig. 1.

In addition, the toilet 100 may further comprise an air pump 160, in particular an air pump 160, for supplying gas, in particular air, to the sampling device 141 of the urine detection system to facilitate its cleaning. More specifically, supplying gas, particularly pumped air, to sampling device 141 may cause contaminants that may remain or accumulate within sampling device 141 to be agitated, such that contaminants may flow out of sampling device 141 with the flow of air, or at least may more easily flow out of sampling device 141 with the flow of water in a cleaning configuration due to loosening of the contaminants.

In an advantageous embodiment, the toilet 100 may further comprise a third valve means 153, for example a solenoid valve, in particular a pressure-stabilizing solenoid valve. The third valve device 153 is configured to regulate water pressure and flow into at least one of the first purge line, the second purge line, and the water outlet line. Thereby, it is avoided that the means for bringing the excessive water flow into communication with the first and/or second washing line, such as the liquid collecting means, the sampling means, and thus their reduced service life or damage due to excessive water pressure, are avoided, since both are relatively delicate means, which cannot withstand large water pressures. Meanwhile, the water outlet flexibility of the water outlet pipeline of the toilet cover can be reduced by controlling the water pressure and the flow of the cleaning water flowing into the toilet cover.

In addition, to further reduce any adverse effects of the water flow on the first purge line and/or the second purge line of the urine test system, the present utility model may further comprise a further adjustment means for adjusting the opening of the first inlet port of the liquid collection device 142 for allowing the purged water to flow therein, thereby controlling the flow rate of the water flow into the liquid collection device 142.

In addition, in embodiments where the urine detection system includes the detection device 143, a further adjustment device may also adjust the second inflow port into the detection device 143 for inflow of water therein for washing to control the flow of water into the detection device 143, thereby reducing any adverse effects on the detection device 143 itself due to flushing.

To facilitate the draining of waste liquid in the liquid collection device 142 of the urine inspection system, the toilet 100 may also include a vacuum pump 170 or other suction device to apply negative pressure to the liquid collection device 142 to cause the waste liquid to drain to a target location, such as the dirt receiving tank 112, as soon as possible.

Next, the flow path arrangement of the toilet 100 according to one embodiment of the present utility model will be further explained with reference to fig. 1. It is understood that the toilet 100 of the present utility model may include other devices not shown in fig. 1 or have other devices instead of the devices shown in fig. 1.

During normal use of the toilet 100, water from a water supply source 200, such as municipal water, flows into the water intake line 120 of the toilet 100. Through the first valve arrangement 151, water can optionally flow into the flush line 130 and optionally the flush valve 132 for the rim and/or bottom flush of the toilet 100.

In a urine testing configuration of the urine testing system, for example, once a month, once a week, once a day, the sampling device 141 samples the urine of the user, for example, mid-stream urine, and urine flows from the sampling device 141 into the liquid collection device 142. The detection device 143 further takes urine from the liquid collection device 142. This may be done at any suitable time after urine is collected in the liquid collection device 142, but is not preferred to be too long. Thus, the urine portion to be measured flows from the liquid collecting device 142 into the detecting device 143. The detection device 143 may or may not include an analysis unit, a data output unit, a communication unit, etc., which will not be described herein.

In a cleaning configuration of the urine detection system, water may be selectively flowed into the urine detection system. In the illustrated embodiment, water may flow directly to the liquid collection device 142, and thus the sampling device 141, via the second valve device 152, and waste liquid may be discharged from the liquid collection device 142 to a urine detection system, such as to the dirt holding tank 112 or the drain 113. The water may also flow through the detection device 143 to the liquid collection device 142 and the sampling device 141, thereby cleaning the detection device 143 as well.

In addition, when the toilet lid 114 is required to provide a flush function, water from the water inlet line 120 may also flow into the water outlet line of the toilet lid 114 via the second valve device 152. Of course, it is also possible to design the water of the water inlet line 120 to be led directly into the water outlet line via the first valve device 151.

The air pump 160, and in particular the air pump, loosens dirt within the sampling device 141 to facilitate cleaning thereof, while the vacuum pump 170 serves to increase the efficiency of the waste liquid being discharged from the liquid collection device 142. During the washing process, a pressure stabilizing solenoid valve may be used to control the opening of the first inlet port of the liquid collecting device 142 and the second inlet port of the detecting device 143, thereby controlling the flow rate of water into these devices.

Next, urine testing and cleaning procedures (from a user perspective) of the exemplary toilet 100 are explained with reference to fig. 2.

First, the user initiates the urine test function on the mobile phone application. After start-up, the urine inspection system and the entire toilet 100 can perform a round of self-inspection to check whether there is a problem. If there is no problem, the toilet 100 may prohibit the normal flushing and the washing function of the toilet 100, thereby avoiding false triggering of flushing or washing functions during urine examination.

Subsequently, the urine detection system samples the urine of the user. The test strip may be included in the detection device 143 or a subsequent analysis unit, the test strip is primed, and the test strip is waiting for a period of time to scan. Then, the scan results are uploaded, and the analysis results are waited for. In this process, the test paper can be recovered.

The urine test system is then switched to a cleaning configuration, for example, the urine test cleaning solenoid valve may be opened, thereby cleaning the liquid collection device 142, the sampling device 141, and the detection device 143.

Finally, the first valve device 151 can be switched to the first operating position for flushing the toilet 100. In addition, the toilet cover 114 may optionally be toilet cleaned.

The analysis results may be presented on a cell phone application, such as a push report. The entire urine test procedure ends.

Although the utility model is described with reference to embodiments of a toilet having a urine sensing function in the various figures, it should be understood that embodiments within the scope of the utility model may be applied to other sanitary fixtures having similar structures and/or functions in addition to such toilets.

The foregoing description has provided numerous features and advantages including various alternative embodiments, as well as details of the structure and function of the devices and methods. The intent herein is exemplary and not exhaustive or limiting.

It will be apparent to those skilled in the art that various modifications can be made in the full scope indicated by the broad general meaning of the terms expressed in the appended claims, especially in matters of structure, material, elements, components, shapes, sizes and arrangements of parts, including combinations of parts within the principles described herein.
