[0001] The utility model relates to the field of massage pool, especially a water inlet mesh cover for a pipeless water pump, the pipeless water pump and the massage pool. BACKGROUND

[0002] In modern life, people's pursuit of leisure and health is increasing, and soft massage pool body is favored by consumers because it can bring comfortable and relaxing experience. However, there are many problems in the technology of such products on the market at present.

[0003] Traditional soft massage pool body usually uses a pipeline pump to realize jet massage, which makes the whole massage system bulky, resulting in large product size, heavy weight, inconvenient transportation, installation and use, and high requirements for the carrying capacity of the placement site. Moreover, the pipeline pump and its supporting facilities are high in cost, which makes the product price high, limiting the market popularization.

[0004] With the development of technology, pipeless pumps have been applied to such pool bodies to solve the problem of bulky massage system. However, some problems and defects have also appeared in the use of pipeless pumps. The water inlet is usually arranged at the center of the surface of the pipeless pump, and the surface of the pipeless pump is opposite to the water storage cavity of the pipeless pump. During daily use, the debris such as hair in the pool can easily block the water inlet, causing the pump to be blocked and even damaged. This not only increases the maintenance cost and time cost of the user, but also affects the user's experience. SUMMARY

[0005] The utility model aims at solving the technical problem that foreign matter in the pool is easily sucked into the water pump through the water inlet. The utility model provides a water inlet mesh cover for a pipeless water pump, a pipeless water pump and a massage pool, which reduces the risk of water inlet blockage and pump operation blockage by arranging a plurality of first water inlets and a plurality of second water inlets on the first side wall and the bottom wall.

[0006] To solve the above technical problems, the embodiment of the utility model discloses a water inlet mesh cover for a pipeless water pump, which comprises:

[0007] a top wall, the top wall comprises a first through hole penetrating through the top wall along a first direction, and the first through hole is used for communicating with a water outlet channel of a water pump body outside;

[0008] a first side wall, the top wall and the first side wall are connected to form a water inlet cavity, the water inlet cavity is used for communicating with a water inlet channel outside, and the top wall faces the water inlet cavity along the first direction;

[0009] a first bottom wall, the first bottom wall is arranged opposite to the top wall along the first direction, and the first bottom wall is connected with the first side wall;

[0010] a plurality of first water inlets, along the circumference, the plurality of first water inlets are spaced apart on the first side wall and penetrate the first side wall, the plurality of first water inlets are used for communicating with the external water storage cavity;

[0011] a plurality of second water inlets, along the circumference, the plurality of second water inlets are spaced apart on the first bottom wall and penetrate the first bottom wall, the plurality of second water inlets are used for communicating with the external water storage cavity;

[0012] By the above technical scheme, the plurality of first water inlets are arranged on the first side wall, and the plurality of second water inlets are arranged on the first bottom wall, so that the water in the external water storage cavity can flow through the water inlet cavity, the external water inlet channel and the external water pump body in sequence through the plurality of first water inlets and the plurality of second water inlets.

[0013] Compared with the prior art, the water inlet is only arranged on the surface of the ductless pump, and once the water inlet is blocked by foreign matters (such as hair) in the water tank, the ductless pump cannot normally obtain sufficient water, thereby causing operation to be blocked, and even causing a risk of damage in a serious case.

[0014] Therefore, the technical scheme selects to arrange a plurality of water inlets on a plurality of surfaces, for example, if the plurality of first water inlets are blocked by foreign matters, at this time, the plurality of second water inlets can still ensure that the water in the water storage cavity enters the water inlet cavity, thereby reducing the risk that all water inlets are blocked, and effectively improving the stability and reliability of equipment operation.

[0015] In addition, if more water inlets are only attempted to be arranged on the top wall of the prior art to reduce the risk that the water inlets are blocked, although the blocking situation can be reduced to a certain extent, a new problem is caused. This causes the size of the ductless pump to be greatly increased, more space is occupied, and production cost is increased.

[0016] The technical scheme arranges a plurality of water inlets on a plurality of surfaces, so that the first side wall and the bottom wall jointly share the excessive number of water inlets on the top wall. Under the premise of ensuring that the water demand of the water pump operation can be met, the overall size of the mesh cover is reduced, thereby reducing the production cost.

[0019] A plurality of third water inlets are arranged on the second side wall and penetrate the second side wall, and the plurality of third water inlets are used for communicating with the external water storage cavity.

[0020] According to the technical scheme, the plurality of third water inlets are arranged on the second side wall, so that the water in the external water storage cavity can flow through the water inlet cavity, the external water inlet channel and the external water pump body in sequence through the plurality of third water inlets.

[0021] If the plurality of first water inlets or the plurality of second water inlets are blocked by foreign matters, the plurality of third water inlets can still ensure that the water in the water storage cavity enters the water inlet cavity, thereby reducing the risk that all the water inlets are blocked, and effectively improving the stability and reliability of equipment operation.

[0022] According to another specific embodiment of the utility model, the water inlet mesh cover for the pipeless water pump comprises a first opening, the first opening is arranged on the first bottom wall, and the first opening communicates with the water inlet cavity.

[0026] The embodiment of the utility model further discloses a pipeless water pump.

[0027] The water inlet mesh cover for the pipeless water pump in any one of the preceding embodiments;

[0028] The water pump body comprises:

[0029] The water inlet channel communicates with the water inlet cavity.

[0030] The water outlet channel is arranged on the water inlet channel in the spacing mode, and the water outlet channel is used for communicating with the external water storage cavity through the first through hole.

[0031] The working process of the water pump is as follows: water from the external water storage cavity enters the water inlet cavity through the plurality of first water inlets and the plurality of second water inlets of the water inlet mesh cover, then flows through the water inlet channel of the water pump body into the water pump body, and then returns to the external water storage cavity through the water outlet channel.

[0032] According to another specific embodiment of the present application, the water pump body comprises:

[0033] The second bottom wall is spaced apart from the first bottom wall of the water inlet mesh cover for the pipeless water pump along the first direction.

[0034] The third side wall is connected with the second bottom wall, and when the water inlet mesh cover for the pipeless water pump comprises the first side wall, the third side wall is spaced apart from the first side wall of the water inlet mesh cover for the pipeless water pump along the second direction; when the water inlet mesh cover for the pipeless water pump comprises the first side wall and the second side wall, the third side wall is spaced apart from the first side wall and the second side wall of the water inlet mesh cover for the pipeless water pump along the second direction, respectively.

[0035] The second protruding structure is protruded from the third side wall, and the second protruding structure extends along the second direction.

[0036] According to the above technical solution, the first bottom wall and the second bottom wall of the water inlet mesh cover are spaced apart, so that the plurality of second water inlets arranged on the first bottom wall can smoothly take in water from the external water storage cavity. If the first bottom wall and the second bottom wall are attached, the plurality of second water inlets will lose the function of taking in water, so that the pipeless water pump cannot normally obtain sufficient water, thereby causing the operation to be blocked.

[0037] The third side wall is spaced apart from the first side wall and the second side wall of the water inlet mesh cover, respectively, so that the plurality of first water inlets arranged on the first side wall and the plurality of third water inlets arranged on the second side wall can smoothly take in water from the external water storage cavity. If the first side wall and the third side wall are attached, the plurality of first water inlets will lose the function of taking in water. Similarly, if the second side wall and the third side wall are attached, the plurality of third water inlets will lose the function of taking in water, so that the pipeless water pump cannot normally obtain sufficient water, thereby causing the operation to be blocked.

[0040] an air inlet for communicating with air outside;

[0041] an air outlet spaced apart from the water outlet channel, the air outlet being configured to communicate with the water storage cavity outside through the first through hole.

[0042] According to the Bernoulli principle in fluid mechanics, the high-speed water flow discharged from the water outlet channel will form a negative pressure environment in the surrounding area, and the air outlet is spaced apart from the water outlet channel and is located in the negative pressure area, so that air enters the water storage cavity outside in the form of bubbles.

[0043] Compared with the existing technology, if the user's back or palm is close to the water outlet channel, and the air outlet is spaced apart from the water outlet channel, the bubbles produced by the air outlet at this time are easily sucked into the water inlet channel by the water inlet on the top wall, so that the pipeless pump cannot normally obtain sufficient water, thereby causing operation to be blocked.

[0044] Therefore, in combination with the foregoing, the first water inlet in the present technical solution is arranged on the first side wall, the second water inlet is arranged on the first bottom wall, the third water inlet is arranged on the second side wall, and the fourth water inlet is arranged on the outer edge of the top wall, all of which are far away from the water outlet channel, thereby reducing the risk of bubbles being sucked into the water inlet channel by the water inlet.

[0079] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0080] Reference Figures 1A to 3The embodiment of the present application provides a water inlet mesh cover 100 (hereinafter referred to as "water inlet mesh cover 100") for a pipeless water pump and a pipeless water pump 200. The pipeless water pump 200 comprises the water inlet mesh cover 100 and a water pump body 210. The water pump body 210 comprises a water inlet channel 211 and a water outlet channel 212. The water inlet channel 211 is arranged apart from the water outlet channel 212. The water outlet channel 212 is used for communicating with an external water storage cavity 311.

[0081] The water inlet mesh cover 100 comprises a top wall 110, a first side wall 120, a first bottom wall 130 and a water inlet portion 150. The top wall 110 comprises a first through hole 111 penetrating through the top wall 110 along a first direction X. The first through hole 111 is circular. The first through hole 111 communicates with the water outlet channel 212. Along the first direction X, the water inlet channel 211 is arranged apart from the top wall 110.

[0082] The top wall 110 is connected with the first side wall 120 to form a water inlet cavity 160. The water inlet cavity 160 communicates with the water inlet channel 211. Along the first direction X, the top wall 110 faces the water inlet cavity 160. Along the first direction X, the first bottom wall 130 is arranged opposite to the top wall 110. The first bottom wall 130 is connected with the first side wall 120.

[0083] The water inlet portion 150 comprises a plurality of first water inlet openings 151 and a plurality of second water inlet openings 152. Along a circumferential direction R, the plurality of first water inlet openings 151 are arranged apart on the first side wall 120 and penetrate through the first side wall 120. The plurality of second water inlet openings 152 are arranged apart on the first bottom wall 130 and penetrate through the first bottom wall 130. The plurality of first water inlet openings 151 and the plurality of second water inlet openings 152 are used for communicating with the external water storage cavity 311.

[0084] It should be noted that the water inlet mesh cover 100 can comprise the plurality of first water inlet openings 151 and the plurality of second water inlet openings 152, or can only comprise the plurality of first water inlet openings 151, or can only comprise the plurality of second water inlet openings 152.

[0085] By arranging the plurality of first water inlet openings 151 on the first side wall 120 and the plurality of second water inlet openings 152 on the first bottom wall 130, water in the external water storage cavity 311 can flow through the water inlet cavity 160, the water inlet channel 211 and the water pump body 210 in sequence through the plurality of first water inlet openings 151 and the plurality of second water inlet openings 152.

[0086] Compared with the prior art, the water inlet opening is only single arranged on the surface of the pipeless pump. Once the foreign matter (such as hair) in the water tank blocks the water inlet opening, the pipeless pump cannot normally obtain sufficient water, thereby causing operation to be blocked, and even causing a risk of damage in a serious case.

[0087] Therefore, the technical scheme selects to arrange multiple water inlets on multiple surfaces. For example, if the multiple first water inlets 151 are blocked by foreign matters, the multiple second water inlets 152 can still ensure that the water in the water storage cavity 311 enters the water inlet cavity 160, thereby reducing the risk that all water inlets are blocked and effectively improving the stability and reliability of the equipment operation.

[0088] In addition, if more water inlets are added to the top wall of the prior art to reduce the risk of water inlet blockage, although the blockage situation can be reduced to a certain extent, new problems will be caused. Doing so will greatly increase the size of the pipeless pump, not only occupying more space, but also increasing the production cost.

[0089] The technical scheme arranges multiple water inlets on multiple surfaces, so that the first side wall 120 and the first bottom wall 130 jointly share the excessive number of water inlets on the top wall 110. Under the premise of ensuring that the water demand of the water pump operation can be met, the overall size of the mesh cover is reduced, thereby reducing the production cost.

[0090] The working process of the water pump is as follows: water from the external water storage cavity 311 enters the water inlet cavity 160 through the multiple first water inlets 151 and the multiple second water inlets 152 of the water inlet mesh cover 100, then flows through the water inlet passage 211 of the water pump body 210 into the water pump body 210, and then returns to the external water storage cavity 311 through the water outlet passage 212.

[0091] It should be noted that the shape of the first water inlet 151 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the shape of the first water inlet 151 can be circular, triangular, etc. The shape of the second water inlet 152 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the shape of the second water inlet 152 can be circular, triangular, etc. The shape of the first through hole 111 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the shape of the first through hole 111 can be rectangular, triangular, etc.

[0092] In some possible implementation manners, with reference to Figures 3 to 5B The water inlet mesh cover 100 includes a second side wall 140, which is spaced apart from the first side wall 120 along a second direction Y to form a cavity 190, and the cavity 190 is in communication with the water inlet cavity 160. One end of the second side wall 140 is connected with the top wall 110, and the other end of the second side wall 140 is connected with the first bottom wall 130, and the second direction Y is perpendicular to the first direction X.

[0093] The water inlet part 150 includes a plurality of rectangular third water inlets 153, which are arranged on the second side wall 140 in a circumferential direction R and penetrate the second side wall 140, and are used for communicating with the external water storage cavity 311.

[0094] It should be noted that the water inlet mesh cover 100 can include the plurality of first water inlets 151, the plurality of second water inlets 152, and the plurality of third water inlets 153, or can include only the plurality of first water inlets 151, or only the plurality of second water inlets 152, or only the plurality of third water inlets 153, or can include the plurality of first water inlets 151 and the plurality of second water inlets 152, or include the plurality of first water inlets 151 and the plurality of third water inlets 153, or include the plurality of second water inlets 152 and the plurality of third water inlets 153.

[0095] By arranging the plurality of third water inlets 153 on the second side wall 140, water in the external water storage cavity 311 can flow through the plurality of third water inlets 153, the water inlet cavity 160, the water inlet channel 211, and the water pump body 210 in sequence.

[0096] If the plurality of first water inlets 151 or the plurality of second water inlets 152 are blocked by foreign matter, the plurality of third water inlets 153 can still ensure that water in the water storage cavity 311 enters the water inlet cavity 160, thereby reducing the risk of all water inlets being completely blocked and effectively improving the stability and reliability of the equipment operation.

[0097] The working process of the water pump is as follows: water from the external water storage cavity 311 enters the water inlet cavity 160 through the plurality of first water inlets 151, the plurality of second water inlets 152, and the plurality of third water inlets 153 of the water inlet mesh cover 100, then flows through the water inlet channel 211 of the water pump body 210 into the water pump body 210, and then returns to the external water storage cavity 311 through the water outlet channel 212.

[0098] It should be noted that the shape of the third water inlet 153 is not limited in the embodiments of the present application, for example, in other possible embodiments, the shape of the third water inlet 153 can be circular, triangular, etc.

[0099] In some possible embodiments, referring to Figure 5B The water inlet mesh cover 100 includes a circular first opening 170 arranged on the first bottom wall 130, which communicates with the water inlet cavity 160.

[0100] It should be noted that the shape of the first opening 170 is not limited in the embodiments of the present application, for example, in other possible embodiments, the shape of the first opening 170 can be rectangular, triangular, etc.

[0101] In some possible embodiments, referring to Figure 3 , Figure 5A and Figure 5B , the water inlet part 150 includes a plurality of fourth water inlet openings 154 in a circular shape, which are arranged at the top wall 110 in a circumferential direction R and penetrate the top wall 110, and are used for communicating with the external water storage cavity 311. A part of the plurality of fourth water inlet openings 154 communicate with the water inlet cavity 160. As can be seen from the drawings, a part of the plurality of fourth water inlet openings 154 directly communicate with the water inlet cavity 160, and another part of the plurality of fourth water inlet openings 154 communicate with the water inlet cavity 160 through the cavity 190 and the plurality of third water inlet openings 153.

[0102] It should be noted that the shape of the fourth water inlet opening 154 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the shape of the fourth water inlet opening 154 can be rectangular, triangular, etc.

[0103] In some possible embodiments, referring to Figure 5B and Figure 6 , the water inlet mesh cover 100 includes a first protruding structure 180, which is protruded from the first bottom wall 130 and extends along the first direction X, and is connected with the water pump body 210.

[0104] In some possible embodiments, referring to Figure 5A , the water inlet mesh cover 100 is circular, or square, or polygonal, or arc-shaped.

[0105] In some possible embodiments, referring to Figure 4A , Figure 4B and Figure 6 , the water pump body 210 includes a second bottom wall 213, a third side wall 214 and a second protruding structure 215. The first bottom wall 130 of the water inlet mesh cover 100 is arranged in a spaced manner with the second bottom wall 213 along the first direction X, and the third side wall 214 is connected with the second bottom wall 213.

[0106] The third side wall 214 is arranged in a spaced manner with the first side wall 120 and the second side wall 140 of the water inlet mesh cover 100 along the second direction Y, respectively. The second protruding structure 215 is protruded from the third side wall 214 and extends along the second direction Y, and the first protruding structure 180 of the water inlet mesh cover 100 is buckled with the second protruding structure 215.

[0107] With the above technical solution, the first bottom wall 130 of the water inlet mesh cover 100 is spaced apart from the second bottom wall 213, so that the plurality of second water inlets 152 arranged on the first bottom wall 130 can smoothly take in water from the external water storage cavity 311. If the first bottom wall 130 is attached to the second bottom wall 213, the plurality of second water inlets 152 will lose the function of taking in water, so that the pipeless water pump 200 cannot normally obtain sufficient water, thereby causing the operation to be blocked.

[0108] The third side wall 214 is spaced apart from the first side wall 120 and the second side wall 140 of the water inlet mesh cover 100, respectively, so that the plurality of first water inlets 151 arranged on the first side wall 120 and the plurality of third water inlets 153 arranged on the second side wall 140 can smoothly take in water from the external water storage cavity 311. If the first side wall 120 is attached to the third side wall 214, the plurality of first water inlets 151 will lose the function of taking in water. Similarly, if the second side wall 140 is attached to the third side wall 214, the plurality of third water inlets 153 will lose the function of taking in water, so that the pipeless water pump 200 cannot normally obtain sufficient water, thereby causing the operation to be blocked.

[0109] In some possible embodiments, with reference to Figure 4A and Figure 4B , the first side wall 120 of the water inlet mesh cover 100 comprises a first threaded hole 121, and the first threaded hole 121 is spaced apart from the plurality of first water inlets 151. The second protruding structure 215 comprises a second threaded hole 2151, and the second threaded hole 2151 is connected to the first threaded hole 121 through a threaded connection or a screw connection.

[0110] It should be noted that the connection mode of the water inlet mesh cover 100 and the water pump body 210 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the water inlet mesh cover 100 and the water pump body 210 can be connected through a high-frequency connection, or through a hot pressing connection or a mechanical clamping connection.

[0111] In some possible embodiments, with reference to Figure 3 , Figure 4A and Figure 4B , the water pump body 210 comprises an air suction device 216, and the air suction device 216 comprises an air inlet 2161 and an air outlet 2162. The air inlet 2161 is used to communicate with the external air, and the air outlet 2162 is spaced apart from the water outlet channel 212 and communicates with the external water storage cavity 311 through the first through hole 111.

[0112] According to the Bernoulli principle in fluid mechanics, the high-speed water flow discharged from the water outlet channel 212 can form a negative pressure environment in the surrounding area, and the air outlet 2162 is arranged in the negative pressure area, so that air enters the water storage cavity 311 in the form of bubbles.

[0113] Compared with the pipeline-free water pump in the prior art, if the back of the user or the palm is close to the water outlet channel, and the air outlet is arranged away from the water outlet channel, then the bubbles produced by the air outlet are easily sucked into the water inlet channel through the water inlet, so that the pipeline-free pump cannot normally obtain sufficient water, thereby causing operation to be blocked.

[0114] Therefore, in combination with the foregoing, the first water inlet 151 is arranged on the first side wall 120, the second water inlet 152 is arranged on the first bottom wall 130, the third water inlet 153 is arranged on the second side wall 140, and the fourth water inlet 154 is arranged on the outer edge of the top wall 110, which are all far away from the water outlet channel 212, thereby reducing the risk of bubbles being sucked into the water inlet channel 211.

[0115] In some possible implementation manners, referring to Figure 4B , the water pump body 210 includes a connecting pipe 217 and a check valve 218, one end of the connecting pipe 217 is connected with the air inlet 2161, and the other end of the connecting pipe 217 is connected with the check valve 218.

[0120] In some possible embodiments, referring to Figure 3 And Figure 8 The soft pool body 310 comprises an outer side wall 315 made of soft material. The channel 314 penetrates the outer side wall 315, and the channel 314 comprises a channel wall 3141 connected with the inner side wall 312 and the outer side wall 315 to form an air chamber 316, and the water pump body 210 is arranged in the air chamber 316.

[0121] It should be noted that the soft pool body 310 in the figure is a double-layer or multi-layer structure, that is, the soft pool body 310 comprises the inner side wall 312 and the outer side wall 315. However, in other possible embodiments, the soft pool body 310 can only comprise the inner side wall 312 or only comprise the outer side wall 315, that is, the soft pool body 310 can also be a single-layer structure, and the embodiments of the present application do not make specific limitations.

[0122] In some possible embodiments, referring to Figure 3 And Figure 8 The soft pool body 310 comprises an outer side wall 315, the inner side wall 312 and the outer side wall 315 are sequentially connected with the bottom wall 313 to form an air chamber 316, and the water pump body 210 is arranged in the air chamber 316.

[0123] It should be noted that although the water pump body 210 is arranged in the air chamber 316, the air inlet 2161 needs to be exposed to the air outside to suck the air outside into the air suction device 216.

[0124] In some possible embodiments, referring to Figure 3 And Figure 6 The massage pool comprises an electric control box 320, and the water pump body 210 is connected with the electric control box 320. In other possible embodiments, the water pump body 210 can also be directly connected with the power supply outside.
