[0001] The present application relates to the technical field of household appliances, in particular to a humidifier main machine and a humidifier. BACKGROUND

[0002] The fog-free humidifier is a kind of humidifier that can increase the humidity of air without generating visible water mist, which can reduce the deposition of water mist on furniture, reduce the breeding of bacteria, and also avoid the potential damage of water mist deposition to furniture and floor.

[0003] In the related art, the fog-free humidifier includes a humidifier main machine and a filter element assembly. The humidifier main machine has a fan assembly and a water storage tray arranged on the fan assembly. The water storage tray is an integral structure with the humidifier main machine. The water storage tray is provided with a water storage groove and an air outlet grille arranged around the outer circumferential side of the water storage groove. The filter element assembly is arranged on the water storage tray. When the fan assembly is running, the airflow blows through the wet filter element in the filter element assembly through the air outlet grille. In this way, the water can be naturally evaporated into the air, thereby achieving the purpose of humidifying the indoor air without fog.

[0004] However, in the related art, after the humidifier main machine stops running, water may remain in the water storage groove. Therefore, when the water in the water storage groove is poured out, the liquid may enter the interior of the humidifier main machine through the air outlet grille, thereby causing the risk of damage to the products inside the humidifier main machine. Utility model content

[0005] In view of the above problems, the embodiments of the present application provide a humidifier main machine and a humidifier, which aim to solve the problem that water easily enters the interior of the humidifier main machine when cleaning the residual water in the water storage tray, thereby improving the safety and reliability of the humidifier.

[0006] In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

[0016] In some embodiments, in the vertical direction, the connection position of the drainage groove and the cavity wall of the containing cavity is higher than the connection position of the drainage groove and the water outlet hole.

[0017] In this way, when the water is drained, the entire humidifier host can be tilted, so that the water drained out of the water outlet hole is guided to the cavity wall of the containing cavity through the drainage groove, and then drained out of the host shell along the cavity wall. In this way, no additional water drainage structure needs to be provided, and the method is simple, easy to implement, and low in cost.

[0018] In some embodiments, the drainage groove has an inclined angle between the extension direction and the horizontal direction.

[0020] In some embodiments, the inclined angle between the extension direction of the drainage groove and the horizontal direction is 15°-75°.

[0021] In this way, the water drainage efficiency can be improved, and the user's use experience is improved.

[0022] In some embodiments, the side wall of the main housing has an openable and closable water outlet connected with the drainage structure.

[0023] In this way, the water drained by the drainage structure can be directly discharged through the water outlet, improving the convenience of water drainage.

[0024] In some embodiments, a blocking member is further included, which is configured to open or close the water outlet.

[0025] In this way, the opening or closing of the water outlet can be effectively controlled, and the problem of accidental water leakage through the water outlet when water drainage is not needed can be prevented, thereby improving the safety and reliability of the humidifier main machine.

[0026] In some embodiments, the blocking member has a blocking portion, which can be inserted into the water outlet to close the water outlet, or removed from the water outlet to open the water outlet.

[0027] In this way, the blocking or opening of the water outlet is simple and effective, and the operation is simple and low in cost.

[0028] In some embodiments, a first sealing member is further included, which is configured to be arranged between the blocking portion and the hole wall of the water outlet to seal the gap between the blocking portion and the water outlet.

[0029] In this way, the sealing between the blocking member and the water outlet can be improved, and the problem of water leakage from the water outlet when the water outlet is closed can be avoided, thereby improving the safety and reliability of the humidifier main machine and the user's use experience.

[0030] In some embodiments, the blocking member further has a limiting portion connected with the blocking portion, and when the blocking portion is inserted into the water outlet, the limiting portion abuts against the outer side wall of the water storage tank.

[0031] In this way, the problem of damage or poor sealing caused by excessive insertion of the blocking portion into the water outlet can be avoided, thereby improving the reliability of the blocking portion when closing the water outlet.

[0032] In some embodiments, the blocking member further has a holding portion arranged on the side of the limiting portion away from the blocking portion.

[0033] In this way, the holding portion can provide a gripping point for the user to conveniently grip the blocking member, thereby improving the safety and comfort of the user when operating the blocking member, and improving the user's use experience.

[0034] In some embodiments, the blocking member is movably connected with the water storage disc to move between a first position and a second position to open or close the water outlet.

[0035] In this way, the convenience of opening and closing the blocking member is improved, and the blocking member is prevented from being lost after being removed from the water outlet.

[0036] In some embodiments, at least one of the blocking member and the water storage tray is provided with a rotating shaft, and the blocking member and the water storage tray are rotationally connected through the rotating shaft.

[0037] In this way, the blocking member can be switched between the first position and the second position by rotating around the rotating shaft, and the operation is smooth and accurate, and the stability of switching the blocking member between the first position and the second position is improved.

[0038] In some embodiments, the humidifier main machine further comprises a second sealing member arranged between the water storage tray and the cavity wall of the containing cavity, and the second sealing member is configured to seal the gap between the side wall of the water storage tray and the containing cavity.

[0039] In this way, the sealing performance of the water storage tray and the cavity wall of the containing cavity after being connected is improved, and the problem of water entering the humidifier main machine is avoided, thereby improving the safety and reliability of the humidifier main machine.

[0065] To make the objectives, technical solutions, and superiorities of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0066] The embodiments of the present application provide a humidifier 10, which can be a mist-free humidifier 10. The mist-free humidifier 10 generally comprises a humidifier main machine 100, a filter core assembly 200, and a water tank assembly 300. The filter core assembly 200 is arranged between the humidifier main machine 100 and the water tank assembly 300. The water tank in the water tank assembly 300 is used to provide a water source for the filter core assembly 200 to humidify the filter core in the filter core assembly 200. The humidifier main machine 100 comprises a motor and a fan. The motor is used to drive the fan to operate. In this way, the fan can drive air to flow and make the flowing air flow pass through the humidified filter core in the filter core assembly 200, so that the moisture on the filter core is naturally evaporated into the air, thereby increasing the humidity of the air in a way of not producing visible water mist, reducing the deposition of visible water mist on furniture, reducing the breeding of bacteria, and also avoiding the potential damage of water mist deposition to furniture and floor.

[0067] The water tank in the water tank assembly 300 is used to store the humidification water of the humidifier 10. The humidification water in the water tank can be pure water, or can also be a water solution with additives such as mixed spices, bactericides, essential oils, etc. The embodiments of the present application do not make specific limitations on this, and the liquid used for humidifying the filter core will be collectively referred to as water below, and will not be specifically described.

[0068] In some embodiments, please refer to Figure 1As shown, the water tank assembly 300 is arranged above the humidifier main machine 100, the filter core assembly 200 is arranged between the humidifier main machine 100 and the water tank assembly 300, the humidifier main machine 100 comprises a main machine shell 110, a fan assembly and a water storage tray 120, the main machine shell 110 has a containing cavity 111, the fan assembly is arranged in the containing cavity 111, the water storage tray 120 is horizontally arranged in the containing cavity 111 and above the fan assembly, the water storage tray 120 has a water storage groove 121 and an air outlet grille 122 arranged around the water storage groove 121, the filter core assembly 200 is arranged on the water storage tray 120, the water tank comprises a water tank, the bottom of the water tank is provided with a lower water hole which can be opened and closed, when the lower water hole is opened, the water in the water tank can humidify the filter core in the filter core assembly 200 through the lower water hole, the main machine shell 110 is provided with an air inlet hole 112 on the side wall close to the bottom, in this way, when the motor drives the fan to run, the airflow entering the containing cavity 111 through the air inlet hole 112 is blown to the humidified filter core along the air duct through the air outlet grille 122 under the drive of the fan, so that the moisture on the filter core is naturally evaporated into the air, thereby achieving the purpose of humidifying the air.

[0069] Since the mist-free humidifier 10 needs the airflow to pass through the humidified filter core, so that the moisture on the filter core is naturally evaporated when the airflow flows through, therefore, the water storage tray 120 below the filter core will remain a certain amount of water when the whole humidifier 10 stops running, and the water storage tray 120 is usually an integral structure with the humidifier main machine 100, therefore, when cleaning the water in the water storage tray 120, the humidifier main machine 100 is usually held as a whole and poured outwards, but when pouring water, the water will pass through the air outlet grille 122, so that the water will enter the inside of the humidifier main machine 100, causing the motor, fan and other devices in the humidifier main machine 100 to be short-circuited by water, and there is also a problem that the other devices in the humidifier main machine 100 are damaged or affected in performance by water, thereby affecting the performance and safety of the whole humidifier 10.

[0070] For the above problems, please refer to Figures 2 to 7As shown, the embodiment of the present application provides a humidifier host 100, which comprises a host shell 110, a water storage disc 120 and a drainage structure 130. The host shell 110 has a containing cavity 111. The water storage disc 120 is horizontally arranged in the containing cavity 111 and is sealingly connected with the cavity wall of the containing cavity 111. The water storage disc 120 has a water storage groove 121 and an air outlet grille 122. The air outlet grille 122 is arranged around the outer circumferential side of the water storage groove 121. The side wall of the water storage groove 121 has an openable water outlet hole 123. The drainage structure 130 is connected with the water outlet hole 123. The drainage structure 130 is configured to drain the water discharged from the water outlet hole 123 to the outside of the host shell 110. In this way, when it is necessary to clean the residual water in the water storage groove 121, the water outlet hole 123 can be directly opened. The water in the water storage groove 121 is drained to the outside of the host shell 110 through the water outlet hole 123 and the drainage structure 130. In this way, the problem that the water is likely to enter the inside of the humidifier host 100 through the air outlet grille 122 when the water is poured through the water storage groove 121 can be avoided. Thus, the safety and reliability of the humidifier host 100 are improved. In addition, the drainage mode is simple and convenient.

[0071] As can be seen from the above scheme, by arranging the openable water outlet hole 123 on the side wall of the water storage groove 121 and the drainage structure 130 connected with the water outlet hole 123, when it is necessary to drain water, the water outlet hole 123 is opened. The water outlet hole 123 is drained to the outside of the host shell 110 through the drainage structure 130, without passing through the air outlet grille 122. Thus, the problem that the water enters the inside of the humidifier host 100 through the air outlet grille 122 can be avoided. In addition, the water storage disc 120 is sealingly connected with the cavity wall of the containing cavity 111. Thus, when the water discharged from the water outlet hole 123 is drained to the outside of the host shell 110 through the drainage structure 130, the water is prevented from entering the inside of the humidifier host 100 through the gap between the water storage disc 120 and the cavity wall of the containing cavity 111. Thus, the safety and reliability of the humidifier host 100 are improved. In addition, the drainage mode is simple and convenient.

[0072] In some embodiments, as shown in Figures 3 to 7 , the drainage structure 130 is connected between the water outlet hole 123 and the cavity wall of the containing cavity 111, so as to drain the water discharged from the water outlet hole 123 and drain it through the cavity wall of the containing cavity 111. Thus, when the water is drained, the water does not need to pass through the air outlet grille 122. Thus, the problem that the water enters the inside of the humidifier host 100 through the air outlet grille 122 can be avoided. Thus, the use safety of the humidifier host 100 is improved.

[0073] For example, Figure 3 , Figure 5 and Figure 7As shown, the drainage structure 130 has a drainage groove 131, which is connected between the water outlet 123 and the cavity wall of the receiving cavity 111. It can be understood that the drainage groove 131 can effectively guide the flow of water discharged from the water outlet 123, thereby improving the smoothness and reliability of drainage.

[0074] To improve the traffic-driving effect of the traffic-driving structure 130, such as Figures 3 to 7 As shown, the connection position between the drainage channel 131 and the cavity wall of the receiving cavity 111 is higher than the connection position between the drainage channel 131 and the water outlet 123. When draining water, the entire humidifier main unit 100 can be tilted so that the water discharged through the water outlet 123 is guided through the drainage channel 131 to the cavity wall of the receiving cavity 111, and then discharged along the cavity wall to the outside of the main unit housing 110. In this way, no additional drainage structure is required, the method is simple, easy to implement, and low in cost.

[0075] To further enhance the traffic generation effect of traffic generation structure 130, please continue to refer to... Figures 3 to 7 As shown, the extension direction of the drainage channel 131 has an inclined angle with the horizontal direction. When draining water, the entire humidifier main unit 100 can be tilted. In this way, the drainage channel 131 can efficiently and smoothly drain the water discharged from the water outlet 123, thereby improving the drainage efficiency.

[0076] For ease of description, such as Figure 5 As shown, the angle of inclination between the extension direction of the drainage channel 131 and the horizontal direction is represented by α, where the value of α is between 0 and 75°.

[0077] For example, the angle between the extension direction of the drainage channel 131 and the horizontal direction is 15° to 75°, that is, α is between 15° and 75°. For example, the angle of α can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 60°, 70°, 75°, etc., so as to guide the water discharged from the water outlet 123, which can improve drainage efficiency and thus improve the user experience.

[0078] In some other embodiments, the drainage structure 130 may also be a drainage pipe (not shown in the figure), one end of which is connected to the water outlet 123, and the other end of which can be directly led out to the outside of the main unit housing 110 to achieve the purpose of draining the residual water in the water storage tank 121.

[0079] In some embodiments, the side wall of the main machine shell 110 is provided with an openable and closable drain port, and the drain port is connected with the drainage structure 130, that is, one end of the drainage pipe is connected with the water outlet hole 123, and the other end is connected with the drain port. In this way, when the water outlet hole 123 is opened for drainage, the drained water is guided to the drain port through the drainage structure 130, and then drained to the outside of the main machine shell 110 through the drain port, so as to further improve the convenience of drainage.

[0080] In some embodiments, the side wall of the main machine shell 110 is provided with an openable and closable drain port, and the drain port is connected with the drainage structure 130, that is, one end of the drainage pipe is connected with the water outlet hole 123, and the other end is connected with the drain port. In this way, when the water outlet hole 123 is opened for drainage, the drained water is guided to the drain port through the drainage structure 130, and then drained to the outside of the main machine shell 110 through the drain port, so as to further improve the convenience of drainage.

[0081] In some embodiments, please refer to Figures 4 to 8 The humidifier main machine 100 further comprises a blocking piece 140, which is configured to open or close the water outlet hole 123, that is, the blocking piece 140 can block the water outlet hole 123 or move away from the water outlet hole 123. When the blocking piece 140 blocks the water outlet hole 123, the water outlet hole 123 is closed. When the blocking piece 140 moves away from the water outlet hole 123, the water outlet hole 123 is opened. In this way, the opening or closing of the water outlet hole 123 can be effectively controlled, and the problem of accidental leakage of water through the water outlet hole 123 when drainage is not needed can be prevented, thereby improving the safety and reliability of the humidifier main machine 100.

[0082] In some embodiments, please refer to Figure 4 and Figure 5 The blocking piece 140 blocks the water outlet hole 123, and the water outlet hole 123 is closed at this time. In Figure 6 and Figure 7 The blocking piece 140 moves away from the water outlet hole 123, and the water outlet hole 123 is opened at this time. The water drained from the water outlet hole 123 flows through the drainage groove 131 and slightly inclines the entire humidifier main machine 100 downward, so that the water in the drainage groove 131 flows along the drainage groove 131 to the cavity wall of the containing cavity 111 and flows out to the outside of the main machine shell 110 along the cavity wall. Since the water is drained through the water outlet hole 123 along the drainage groove 131 and the cavity wall of the containing cavity 111, the water will not be drained through the air outlet grille 122, thereby avoiding the risk of water entering the interior of the humidifier main machine 100 through the air outlet grille 122. In addition, the water storage tray 120 is sealingly connected with the cavity wall of the containing cavity 111, so that the water flowing through the cavity wall of the containing cavity 111 will not enter the interior of the humidifier main machine 100 along the cavity wall, thereby improving the safety and reliability of the humidifier main machine 100.

[0083] Please continue to refer to Figure 5 , Figure 7 andFigure 8 As shown, the blocking member 140 has a blocking portion 141, which can be inserted into the water outlet hole 123 to close the water outlet hole 123, or removed from the water outlet hole 123 to open the water outlet hole 123, so that the blocking portion 141 can block or open the water outlet hole 123 by plugging, which is simple, effective and low in cost.

[0084] For example, the blocking portion 141 can be a columnar structure, for example, the blocking portion 141 can be a cylindrical structure with a circular, elliptical, square, polygonal or any other shape cross section, which is not limited herein.

[0085] For example, in Figure 8 , the blocking portion 141 is a cylindrical structure with a circular cross section, and the water outlet hole 123 is a circular hole matched with the blocking portion 141, so that the blocking portion 141 can be inserted into the water outlet hole 123 to block the water outlet hole 123 (as shown in Figure 5 ), or removed from the water outlet hole 123 to open the water outlet hole 123 (as shown in Figure 7 ).

[0086] When the blocking portion 141 is inserted into the water outlet hole 123, in order to improve the sealing between the blocking portion 141 and the water outlet hole 123, and avoid the problem of water leakage when the water outlet hole 123 is closed, in the embodiments of the present application, a first sealing member 150 is further included, which is configured to be arranged between the blocking portion 141 and the hole wall of the water outlet hole 123 to seal the gap between the blocking portion 141 and the water outlet hole 123, so as to improve the sealing between the blocking member 140 and the water outlet hole 123, avoid the problem of water leakage when the water outlet hole 123 is closed, and thus improve the safety and reliability of the humidifier main machine 100 and the user's experience.

[0087] For example, the first sealing member 150 includes but is not limited to a sealing ring, as shown in Figures 4 to 8 , the first sealing member 150 is a first sealing ring, which is sleeved on the blocking portion 141, and the mounting mode between the first sealing member 150 and the blocking portion 141 is simple and easy to operate.

[0088] In order to avoid the first sealing member 150 moving on the blocking portion 141 when the blocking member 140 is plugged in or pulled out, in some embodiments, please refer to 8, the sidewall surface of the blocking portion 141 has a limiting groove 1411 extending in the circumferential direction, and the first sealing member 150 is located in the limiting groove 1411, so as to limit the first sealing member 150 in the plugging direction of the blocking portion 141, avoid the first sealing member 150 moving relative to the blocking portion 141, and thus improve the reliability of the relative position between the first sealing member 150 and the blocking portion 141.

[0089] In addition, in order to avoid the transition insertion of the plugging part 141 when being inserted into the water outlet hole 123, in the embodiment of the present application, please continue to refer to Figures 4 to 8 As shown in the figure, the plugging member 140 further has a limiting part 142 connected with the plugging part 141, when the plugging part 141 is arranged in the water outlet hole 123, the limiting part 142 abuts against the outer side wall of the water storage tank 121, which can avoid the problem of damage or poor sealing caused by the transition insertion of the plugging part 141 into the water outlet hole 123, thereby improving the reliability of the plugging part 141 closing the water outlet hole 123.

[0090] For example, as shown in the figure, Figure 8 As shown in the figure, the limiting part 142 can be a limiting plate, the projection area of the limiting plate in the plug-in direction of the plugging member 140 is greater than the area of the water outlet hole 123, so that when the plugging part 141 is inserted into the water outlet hole 123, at least part of the structure of the limiting plate abuts against the outer side wall of the water storage tank 121 to limit the insertion depth of the plugging part 141, so as to avoid the influence of the transition insertion of the plugging part 141 into the water outlet hole 123 on the plugging effect.

[0091] In some embodiments, please continue to refer to Figures 4 to 8 As shown in the figure, the plugging member 140 further has a holding part 143 arranged on the side of the limiting part 142 away from the plugging part 141, so that the holding part 143 can provide a gripping point for the user to conveniently grip the plugging member 140, thereby improving the safety and comfort of the user when operating the plugging member 140, and thus improving the user's experience.

[0092] The holding part 143 includes but is not limited to a convex structure for easy holding, as long as it is convenient for the user to hold, which is not limited here.

[0093] For example, the holding part 143 can further be provided with a holding recess matched with the human finger.

[0094] In addition, in order to avoid the problem of being not easy to store after the plugging member 140 opens the water outlet hole 123 and thus being lost, in the embodiment of the present application, the plugging member 140 is movably connected with the water storage disc 120, so that the plugging member 140 moves between the first position and the second position to open or close the water outlet hole 123, for example, the plugging member 140 moves to the first position to close the water outlet hole 123, and moves to the second position to open the water outlet hole 123, but the plugging member 140 is always connected with the water storage disc 120, so that the problem of the plugging member 140 being lost due to falling is avoided, so as to facilitate the storage of the plugging member 140 after opening the water outlet hole 123, and improve the convenience of opening and closing of the plugging member 140.

[0095] In some embodiments, please refer to Figures 8 to 10As shown in the figures, the at least one of the blocking member 140 and the water storage tray 120 is provided with a rotating shaft 144, and the blocking member 140 and the water storage tray 120 are rotationally connected through the rotating shaft 144. The blocking member 140 can be switched between the first position and the second position by rotating around the rotating shaft 144, which is smooth, accurate, and improves the stability of the switching of the blocking member 140 between the first position and the second position.

[0096] For example, in Figure 8 and Figure 10 , the side wall of the blocking member 140 is provided with the rotating shaft 144, and the groove wall of the drainage groove 131 in the water storage tray 120 is provided with a mounting hole 132 matched with the rotating shaft 144, and the rotating shaft 144 is rotationally mounted in the mounting hole 132. In this way, the blocking member 140 can rotate around the axis of the rotating shaft 144, so that the blocking member 140 can be switched between the first position and the second position. For example, when the blocking member 140 is rotated to the first position, the blocking part 141 in the blocking member 140 is inserted into the water outlet hole 123 (as shown in Figure 5 ), so as to close the water outlet hole 123. When it is needed to drain water, the blocking member 140 can be turned over so that the blocking part 141 is pulled out of the water outlet hole 123, so that the water in the water storage groove 121 is drained through the water outlet hole and the drainage groove 131. After the drainage is completed, the blocking member 140 is turned over and inserted into the water outlet hole 123, so that the water storage tray 120 can normally store water. The drainage is convenient, fast, safe and reliable.

[0097] It should be noted that the first position refers to the position of the blocking member when the water outlet hole is closed, and the second position refers to any position that the blocking member can reach after the water outlet hole is opened.

[0098] In some embodiments, please refer to Figure 3 and Figure 10 , the humidifier main machine 100 further comprises a second sealing member 160, which is arranged between the water storage tray 120 and the cavity wall of the containing cavity 111. The second sealing member 160 is configured to seal the gap between the side wall of the water storage tray 120 and the cavity wall of the containing cavity 111, so as to improve the sealing performance of the water storage tray 120 after being connected with the cavity wall of the containing cavity 111, avoid the problem that water enters the inside of the humidifier main machine 100 along the cavity wall of the containing cavity 111, and thus improve the safety and reliability of the humidifier main machine 100.

[0099] Among them, the second sealing member 160 includes but is not limited to a second sealing ring. For example, as shown in Figure 3 , the second sealing member 160 is a second sealing ring, which is sleeved on the outer circumferential side of the water storage tray 120, so as to seal the gap between the cavity wall of the containing cavity 111 and the side wall of the water storage tray 120 through the second sealing ring.

[0100] In order to improve the reliability of the relative position between the second sealing ring and the water storage disc 120, in the embodiment of the present application, as shown in Figure 9 the outer side wall of the water storage disc 120 is provided with a mounting groove 124 extending in the circumferential direction, and the second sealing ring is arranged in the mounting groove 124 (as shown in Figure 5 and Figure 7 ), so that the second sealing ring is prevented from moving relative to the side wall of the water storage disc 120, thereby improving the stability and reliability of the relative position between the second sealing ring and the water storage disc 120.

[0101] The material of the first sealing ring and the second sealing ring can be plastic, rubber or the like with good sealing performance, which is not specifically limited herein.

[0102] In some embodiments, the drainage structure 130 and the water storage disc 120 can be formed as an integral structure by an integral molding process such as injection molding or casting, so that the installation process can be reduced and the process cost can be reduced.

[0103] In summary, in the humidifier main machine provided by the embodiment of the present application, by arranging a drainage structure and a closable water outlet hole on the side wall of the water storage tank, when it is necessary to clean the residual water in the water storage tank, the water outlet hole can be directly opened, the water in the water storage tank is drained through the water outlet hole and the drainage structure and discharged to the outside of the main machine shell, so that the problem that the water easily enters the inside of the humidifier main machine when the water is poured through the air outlet grille can be avoided, thereby improving the safety and reliability of the humidifier main machine, and the drainage method is simple and convenient.
