Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] At present, refrigerators may be equipped with an ice maker to provide users with ice cubes for daily use. The ice maker is generally arranged in an ice making chamber isolated from a refrigerator or a freezer, and uses an ice making grid to condense ice making water to form ice cubes.

[0003] There are many structures of ice cube trays, and open ice cube trays are one of the more common ones. Open ice cube trays have multiple grids that are open to the top, and there are usually water channels between adjacent grids for water to flow. When the water injection pipe transports ice-making water to the ice cube tray, the ice-making water flows through the water channel to each grid inside the ice cube tray, so that each grid in the ice cube tray is filled with a certain amount of ice-making water. As the ice-making water absorbs the coldness inside the refrigerator, the ice-making water filled in each grid condenses into ice cubes.

[0004] Since the existing water injection pipe is generally equipped with only one water outlet, when the ice-making water falls into the ice-making grid through the only water outlet of the water injection pipe, it will first be concentrated in the area near the water drop point, and then flow to other areas of the ice-making grid through the water trough. However, under the influence of the surface tension of the liquid, it is difficult for the ice-making water to flow and spread evenly around the water drop point, resulting in too much water in the grid near the water drop point and insufficient water in the grid far from the water drop point. The ice cubes prepared in the ice-making grid are of different sizes and are easy to stick together. Utility Model Content

[0033] Box;

[0034] An ice-making assembly, which is arranged in the box and can prepare ice cubes from ice-making water; wherein the ice-making assembly includes:

[0035] An ice making tray, wherein the ice making tray comprises a plurality of ice trays, each of the plurality of ice trays has openings arranged in the same direction, and some or all of the ice trays are provided with water channels for the ice making water to pass through;

[0041] Compared with the prior art, the refrigerator of the utility model has the following beneficial effects:

The first water injection hole of the water injection section is completely discharged, and it will flow toward the tail of the water injection section, so that the ice-making water can flow through all the water injection holes of the water injection section and be dispersedly injected into the ice-making grid from multiple water injection holes, so that multiple ice grids can store ice-making water at the same time, thereby expanding the water drop point area in the ice-making grid. The ice-making water flows and diffuses from different water drop point areas to other ice grids on the side, so that the flow distance of the ice-making water flowing and diffusing to all the ice grids is shortened, thereby reducing the influence of the liquid surface tension on the flow and diffusion of the ice-making water to all the ice grids, so that the water storage of each ice grid in the ice-making grid can be more uniform.

In addition, the water injection section of the water injection pipe of the present application is arranged in a non-planar manner with the ice-making grid, so that the ice grid facing the water injection hole is not in the same straight line, so that the water drop points formed by multiple water injection holes can be dispersedly arranged, so that after the ice-making water is injected into the ice-making grid, it can be more easily spread to all the ice grids.

[0060] The refrigerator 100 provided in the embodiment of the utility model can have various implementation forms. Figures 1 to 10 This is a specific implementation of the refrigerator 100 of the utility model. In this embodiment, the refrigerator 100 includes a cabinet 1A, a refrigeration system (not shown), an air supply system (not shown), and a door 3A.

[0061] The directions described in the text are based on the direction in which the user faces the refrigerator 100, wherein the left and right sides are distinguished by the direction in which the user faces the refrigerator 100, the side facing the user when the refrigerator 100 is in use is defined as the front side, and the side opposite thereto is defined as the rear side, and the upper and lower sides of the refrigerator 100 when generally working normally are defined to distinguish the up and down.

[0062] like Figure 1As shown, the box 1A is used to form the overall appearance of the refrigerator 100. The box 1A is roughly in the shape of a rectangular parallelepiped frame. The top of the box 1A and the bottom of the box 1A are opposite ends. From the top of the box 1A to the bottom of the box 1A is the height direction of the box 1A. The left side of the box 1A and the right side of the box 1A are opposite sides. From the left side of the box 1A to the right side of the box 1A is the width direction of the box 1A. The front side of the box 1A and the rear side of the box 1A are opposite sides. From the front side of the box 1A to the rear side of the box 1A is the thickness direction of the box 1A. The box 1A includes an inner liner and a box shell. The inner liner is arranged in the box shell, and an installation space is formed between the two, which is used to install other component structures of the refrigerator 100 and form a foam insulation layer. A refrigeration chamber 10A for placing goods is formed inside the inner tank. The refrigeration chamber 10A is provided with a chamber opening 10a, which is arranged toward the front side of the box body 1A. The refrigeration chamber 10A can be in a refrigerated temperature environment, a frozen temperature environment, or a normal temperature environment. A door body 3A is provided at the chamber opening 10a. The door body 3A is arranged in a straight plate shape at the front side of the box body 1A. The door body 3A can be connected to the box body 1A in an openable and closable manner to open or close the refrigeration chamber 10A.

[0063] The refrigeration system is used to provide cold air to the refrigeration chamber 10A; the refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a filter drier, a return air pipe, a throttling device, and a refrigerant. Each component is distributed at different positions of the cabinet 1A according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process, and an evaporation process. The compression process is: after the power cord of the refrigerator 100 is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a filter drier to remove moisture and impurities and then flows into the throttling device, and the throttling and pressure reduction are performed through the throttling device, and the refrigerant becomes a wet vapor at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat to gasify, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the change of the state of the refrigerant, and the heat in the refrigerator 100 is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator 100.

[0064] The air supply system is installed in the box 1A, and is used to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box 1A. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box 1A is also defined to form an air duct cavity, which is connected to the air supply duct and the refrigeration chamber 10A respectively, so that the air supply duct is connected to the refrigeration chamber 10A through the air duct cavity; it should be noted that the inner liner is provided with an air outlet, and the air outlet is used to connect the air duct cavity and the refrigeration chamber 10A. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber 10A to cool the refrigeration chamber 10A. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall on the side opposite to the opening 10a of the inner tank and the refrigeration chamber 10A or on the side adjacent to the opening 10a of the refrigeration chamber 10A of the inner tank; it should also be noted that the refrigeration system and the air supply system belong to common knowledge in the field and will not be described in detail here.

[0065] In the above refrigerator 100, reference Figures 1 to 10 The refrigeration chamber 10A is provided with an ice-making assembly 2A for preparing ice cubes. Generally speaking, the ice-making process of the ice-making assembly 2A is as follows: water is injected into the mold for holding liquid inside the ice-making assembly 2A, and cold energy is provided to the ice-making chamber so that the water in the mold freezes into ice cubes, and then the ice cubes are demolded from the mold and fall into the ice storage box for users to take.

[0066] The ice-making assembly 2A provided in this embodiment uses an open ice-making grid 1 to prepare ice cubes. Specifically, the ice-making assembly 2A includes an ice-making grid 1 and a water injection pipe 2, wherein the ice-making grid 1 has a plurality of ice grids 1a, the tops of the plurality of ice grids 1a all have openings 10a arranged in the same direction, and a water trough is provided between two adjacent ice grids 1a for the passage of water for ice making.

[0067] It can be understood that the ice-making grid 1 can be configured with a specific structure of the ice grid 1a according to the user's ice-making needs. For example, the water trough can be set only between some of the ice grids 1a, so that the water for ice-making flows along a specified path in the ice-making grid 1. Alternatively, multiple ice grids 1a can be configured in specific numbers according to the amount of ice made at a single time, and arranged in a rectangular array.

[0068] The water injection pipe 2 is disposed above the ice making tray 1. Furthermore, the water injection pipe 2 is connected to the water system of the refrigerator 100, and can draw ice making water from the water system of the refrigerator 100 and inject it into the ice making tray 1. Figure 2-10The water injection pipe 2 of this embodiment includes an input section 2a and a water injection section 2b, wherein the input section 2a is used to connect with the water system of the refrigerator 100 to introduce ice-making water and make the ice-making water flow along the length direction of the water injection pipe 2; the water injection section 2b is connected to the input section 2a, and the water injection section 2b is arranged at the tail of the input section 2a along the length direction of the water injection pipe 2, so that the ice-making water can enter the water injection section 2b in the forward direction along the flow direction.

[0069] The water injection section 2b is provided with a plurality of water injection holes 22b arranged toward the opening 10a, and the aperture of the water injection hole 22b is smaller than the inner diameter of the water injection pipe 2 at the input section 2a, and the plurality of water injection holes 22b are arranged in sequence on the flow path of the ice-making water along the flow direction of the ice-making water, and the plurality of water injection holes 22b are arranged on the same horizontal plane.

[0070] After the ice-making water enters the water injection pipe 2 from the input section 2a, it flows along the length direction of the water injection pipe 2 and enters the water injection section 2b from the input section 2a. Since the diameter of the water injection hole 22b is smaller than the inner diameter of the water injection pipe 2 at the input section 2a, the ice-making water will not flow out from the first water injection hole 22b near the end of the input section 2a, but will flow along the length direction of the water injection pipe 2, that is, its own flow direction, to the end of the water injection section 2b. In this way, the ice-making water will flow through all the water injection holes 22b in the water injection section 2b, and flow out from each water injection hole 22b and fall into the ice-making tray 1.

[0071] It is understandable that, since the water injection holes 22b are arranged on the flow path of the ice-making water, when the ice-making water flows in the water injection section 2b, the ice-making water can spread and cover all the water injection holes 22b. Since multiple water injection holes 22b are arranged on the same horizontal plane, based on the fluidity of the liquid and the effect of gravity, the ice-making water will not be concentrated at a certain water injection hole 22b, but will be dispersed to each water injection hole 22b, so that the ice-making water can flow out relatively evenly from multiple water injection holes 22b, forming multiple water drop points in the ice-making grid 1. In this way, the ice-making grid 1 can have a larger water drop point area, and the ice-making water flows and spreads from different water drop point areas to other ice grids 1a on the side, so that the flow distance of the ice-making water flowing and spreading to all ice grids 1a is shortened, thereby reducing the influence of the surface tension of the liquid on the flow and diffusion of the ice-making water to all ice grids 1a, so that the water storage of each ice grid 1a in the ice-making grid 1 can be more uniform.

[0072] It should be noted that, inside the water injection pipe 2, the multiple water injection holes 22b are arranged on the same horizontal plane in various structural forms, such as the area where the multiple water injection holes 22b are arranged can be a flat plane, or can be an area where a guide structure or a diversion structure is arranged between adjacent water injection holes 22b. The structure of the area where the water injection holes 22b are located can be configured according to the parameters of the ice making assembly 2A. For example, this embodiment provides another example of a refrigerator 100, referring to Figure 1-2 , Figure 5-6 The ice making device comprises a box body 1A, in which an ice making assembly 2A is arranged to prepare ice cubes from ice making water.

[0073] The ice making assembly 2A includes an ice making grid 1 and a water injection pipe 2, wherein the ice making grid 1 has a plurality of ice grids 1a, the tops of the plurality of ice grids 1a all have openings 10a arranged in the same direction, and all the ice grids 1a are provided with water channels for the passage of ice making water.

[0074] The water injection pipe 2 is disposed above the ice making tray 1. Furthermore, the water injection pipe 2 is connected to the water system of the refrigerator 100, and can draw ice making water from the water system of the refrigerator 100 and inject it into the ice making tray 1. Furthermore, the water injection pipe 2 includes an input section 2a and a water injection section 2b, wherein:

[0075] The input section 2a is used to connect with the water system of the refrigerator 100 to introduce ice-making water and make the ice-making water flow along the length direction of the water injection pipe 2; the water injection section 2b is connected to the input section 2a, and the water injection section 2b is arranged at the tail of the input section 2a along the length direction of the water injection pipe 2, so that the ice-making water can enter the water injection section 2b in the flow direction. In addition, the water injection section 2b is provided with a water injection surface 20b located on the flow path of the ice-making water, and the water injection surface 20b is a horizontal surface extending along the flow direction of the ice-making water, and a plurality of water injection holes 22b arranged in sequence are provided on the water injection surface 20b, and the aperture of the water injection hole 22b is smaller than the inner diameter of the water injection pipe 2 at the input section 2a.

[0076] It can be understood that the refrigerator 100 of this example and the refrigerator 100 of the aforementioned example also have multiple water injection holes 22b arranged on the same horizontal plane, so the refrigerators 100 of the two examples can both achieve the effect of making the water storage of each ice tray 1a in the ice tray 1 more uniform.

[0077] It is understandable that the hole area size of each water injection hole 22b will affect the flow rate of ice-making water in each water injection hole 22b. If the hole area of ​​the water injection hole 22b close to the input section 2a is too large, when the flow rate of ice-making water is insufficient, ice-making water may flow out from these water injection holes 22b, resulting in insufficient flow rate of the water injection holes 22b far from the input section 2a. Therefore, the hole area size of the water injection hole 22b can be limited so that the ice-making water can flow out evenly from each water injection hole 22b.

[0078] As an example of this embodiment, refer to Figure 5-6 , the hole areas of the multiple water injection holes 22b are equal, and the sum of the hole areas of the multiple water injection holes 22b is smaller than the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a. In this way, the hole area of ​​a single water injection hole 22b will be much smaller than the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a, and the flow rate of a single water injection hole 22b is also much smaller than the flow rate of the water injection pipe 2. Therefore, when the ice-making water flows from the input section 2a to the injection section, the ice-making water will not be completely discharged from the water injection holes 22b close to the input section 2a, so the ice-making water can flow in the forward direction along the flow direction to the tail of the injection section, thereby covering all the water injection holes 22b. Of course, in other implementation examples, the sum of the hole areas of the multiple water injection holes 22b can also be equal to the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a. In this way, the hole area of ​​a single water injection hole 22b can be much smaller than the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a, and the flow rate of a single water injection hole 22b is much smaller than the flow rate of the water injection pipe 2, so that the water used for ice making can also flow in the forward direction along the flow direction to the tail of the injection section and cover all the water injection holes 22b.

[0079] In other implementation examples, the hole area of ​​the water injection hole 22b can also be gradually increased along the flow direction of the ice-making water, that is, from the input section 2a to the injection section, the hole area of ​​the water injection hole 22b is gradually increased, so that the hole area of ​​the water injection hole 22b close to the input section 2a is smaller than the hole area of ​​the water injection hole 22b far from the input section 2a, so that the flow rate of the water injection hole 22b close to the input section 2a will be smaller than the flow rate of the water injection hole 22b far from the input section 2a. In this case, the area of ​​multiple water injection holes 22b is limited, such as the sum of the hole areas of multiple water injection holes 22b is less than or equal to the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a, and the flow rate of a single water injection hole 22b is much smaller than the flow rate of the water injection pipe 2, so that the ice-making water can also flow in the forward direction along the flow direction to the tail of the injection section, covering all the water injection holes 22b, which is not illustrated here.

[0080] refer to Figure 2-3 In the ice making tray 1 of this embodiment, a plurality of ice trays 1a are arranged in a rectangular array, forming a layout design of two columns and six rows. Of course, in other examples, the ice tray 1a can also be configured as other layout designs of multiple rows and multiple columns or other array layout designs, such as three rows and four columns, four rows and two columns, or a circular array, etc., according to the demand for single ice making.

[0081] Generally speaking, the ice making tray 1 is placed horizontally so that the ice making water can be relatively stable in each ice tray 1a to prevent the ice making water from spilling out of the ice tray 1a. In this way, the water injection section 2b of the water injection pipe 2 will be arranged in parallel with the ice making tray 1, and in order to form multiple scattered water drop points in the ice making tray 1, as an example of this embodiment, the water injection section 2b can be arranged in a different plane from the ice making tray 1, so that the ice tray 1a facing the water injection hole 22b is not in the same straight line, that is, the water drop points formed by the water injection hole 22b are not in the same row or column. When ice-making water is injected into the ice-making grid 1 from each water injection hole 22b, the ice-making water can be dispersedly injected into ice grids 1a in different vertical columns or horizontal rows of the ice-making grid 1. Since the ice-making water is dispersed in different areas of the ice-making grid 1, the ice-making water can be more easily diffused from these ice grids 1a to the remaining ice grids 1a, thereby preventing the ice-making water from accumulating in a certain row of ice grids 1a or a certain column of ice grids 1a to form sticky ice cubes.

[0082] It is understandable that the diffusion rate of ice-making water in the water injection section 2b will affect the flow rate of each water injection hole 22b, especially the flow rate of the water injection hole 22b located at the end of the water injection section 2b. Since multiple water injection holes 22b are arranged in the water injection section 2b in a structural form arranged on the same horizontal plane, the flow and diffusion of ice-making water in the water injection section 2b depends to a large extent on its own fluidity and the flow rate when entering the water injection section 2b. Therefore, in order to speed up the diffusion efficiency of ice-making water in the water injection section 2b, reference is made to Figure 4 As an example of this embodiment, the input section 2a includes a first end 20a and a second end 21a, wherein the first end 20a is far away from the water injection section 2b, and the first end 20a is the starting point for the ice-making water to enter the water injection pipe 2; the second end 21a is connected to the water injection section 2b, and the second end 21a is the end point for the ice-making water to leave the input section 2a; and the input section 2a is inclined to the ice-making grid 1, so that the input section 2a gradually approaches the ice-making grid 1 from the first end 20a to the second end 21a, so that when the ice-making water flows in the input section 2a, it can obtain a certain flow rate based on its own gravity and rush into the water injection section 2b, so that the ice-making water can quickly diffuse to each water injection hole 22b in the water injection section 2b.

[0083] In order to prevent ice-making water from accumulating inside the water injection pipe 2, a diversion structure can be provided in the water injection section 2b to make the ice-making water converge to the water injection hole 22b. Figure 5-10 As an example of this embodiment, the water injection section 2b further includes a guide surface 21b, which extends along the arrangement direction of the water injection holes 22b, and the guide surface 21b is configured to guide the ice-making water to converge to the water injection holes 22b.

[0084] It is understandable that when the water injection pipe 2 adopts a different structural design, the guide surface 21b can adopt a corresponding design. For example, when the outer contour of the water injection pipe 2 at the water injection section 2b is a square, a layout surface 23b is provided at the bottom of the water injection section 2b, and the layout surface 23b is a plane, and the water injection holes 22b are all provided at the bottom of the water injection pipe 2, and a plurality of water injection holes 22b are arranged on the layout surface 23b.

[0085] The guide surface 21b is a plane and is arranged at the bottom of the water injection pipe 2. The guide surfaces 21b are arranged on both sides of the layout surface 23b and are arranged obliquely to the layout surface 23b. One end of each guide surface 21b is connected to the corresponding side wall of the water injection pipe 2, and the other end is connected to the layout surface 23b, so that the ice making water is gathered to the water injection hole 22b.

[0086] After the ice-making water enters the water injection section 2b, since the water injection hole 22b is sandwiched by the guide surfaces 21b on both sides, no matter the amount of ice-making water is sufficient or insufficient, the ice-making water entering the water injection section 2b can always be gathered in the area where the layout surface 23b is located, so that the ice-making water can always accumulate at the water injection hole 22b, ensuring that the ice-making water can be discharged from the water injection hole 22b to the water injection pipe 2.

[0087] Under the constraint of the water injection hole 22b, the discharge amount and injection amount of ice-making water may be different, and the injection amount of ice-making water input into the water injection section 2b may be greater than the discharge amount of ice-making water discharged from the water injection hole 22b. In this case, it is possible to consider expanding the pipe volume of the water injection pipe 2 in the water injection section 2b so that the water injection pipe 2 can store more ice-making water in the water injection section 2b. Figure 7-8 As an example of this embodiment, the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a is smaller than the hole area of ​​the cross section of the water injection pipe 2 at the water injection section 2b, and the input section 2a is coaxially arranged with the water injection section 2b. In addition, a plurality of water injection holes 22b are arranged on the same straight line, and the water injection holes 22b are arranged in the middle of the water injection section 2b.

[0088] Since the hole area of ​​the cross section of the water injection pipe 2 at the input section 2a is smaller than the hole area of ​​the cross section of the water injection pipe 2 at the water injection section 2b, correspondingly, the pipe volume of the water injection section 2b at the input section 2a will be smaller than the pipe volume of the water injection pipe 2 at the water injection section 2b. In this way, the water injection section 2b can accommodate more water for ice making, and the water injection holes 22b are arranged in the middle of the water injection section 2b, and multiple water injection holes 22b are arranged on the same straight line, which can ensure that the ice making water can flow to each water injection hole 22b, avoiding insufficient water in the water injection holes 22b at the tail of the water injection section 2b.

[0089] In summary, the refrigerator 100 provided in the present embodiment is provided with a water injection pipe 2 of an ice-making assembly 2A, so that the input section 2a and the water injection section 2b of the water injection pipe 2 can be connected in the forward direction along the flow direction of the ice-making water, so that the ice-making water can maintain a forward flow in the water injection pipe 2, ensuring the smooth flow of the ice-making water. Moreover, the water injection pipe 2 of the present application is provided with a plurality of water injection holes 22b facing the opening 10a of the ice tray 1a in the water injection section 2b, and the apertures of these water injection holes 22b are smaller than the inner diameter of the water injection pipe 2 in the input section 2a. In this way, after the ice-making water flows from the input section 2a to the water injection section 2b, since the flow area of ​​the water injection holes 22b is smaller than the flow area of ​​the input section 2a, the ice-making water does not Instead of being completely discharged from the first water injection hole 22b closest to the input section 2a, the water will flow toward the tail of the water injection section 2b, so that the ice-making water can flow through all the water injection holes 22b of the water injection section 2b, and be dispersedly injected into the ice-making grid 1 from multiple water injection holes 22b, so that multiple ice grids 1a can store ice-making water at the same time, thereby expanding the water drop point area in the ice-making grid 1, and the ice-making water flows and diffuses from different water drop point areas to other ice grids 1a on the side, so that the flow distance of the ice-making water flowing and diffusing to all the ice grids 1a is shortened, thereby reducing the influence of the liquid surface tension on the flow and diffusion of the ice-making water to all the ice grids 1a, so that the water storage of each ice grid 1a in the ice-making grid 1 can be more uniform.

[0090] Moreover, the water injection pipe 2 of this embodiment is provided with a guide surface 21b, and the guide surface 21b is used to guide the ice-making water to converge to the water injection hole 22b, so as to avoid the ice-making water from accumulating in the water injection pipe 2, and also enable the ice-making water to better converge to the water injection hole 22b, so that the ice-making water can be discharged from the water injection hole 22b in time. In addition, the water injection section 2b of the water injection pipe 2 of this embodiment is arranged on the opposite side of the ice-making grid 1, so that the ice grid 1a facing the water injection hole 22b is not on the same straight line, so that the water drop points formed by the multiple water injection holes 22b can be dispersedly arranged, so that after the ice-making water is injected into the ice-making grid 1, it can more easily spread to all the ice grids 1a.

[0091] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
