Description

Technical Field

[0001] The utility model relates to the technical field of pool equipment, in particular to a controller with a waterproof structure and pool equipment. Background Art

[0002] Due to the requirements of the working environment, pool equipment often needs to have a certain degree of waterproofness. In particular, the controller inside it for installing the control circuit is also required to have a certain waterproof performance. However, in order to achieve the waterproof effect of the controller, the existing controller structures of pool equipment, such as Figure 1 shown, generally preset a sealing ring on the rear shell of the controller. During installation, the end of the cover opening of the front cover is directly pressed and fixed on the sealing ring on the rear shell. The disadvantage of this structure is that the sealing ring is sandwiched between the front cover and the rear shell, leaving obvious gaps on the outer surface of the installed controller, thus affecting the aesthetics of the product. There is also a part of the controller structure of pool equipment, such as Figure 2 shown, generally adds a groove on the end face of the side wall of the front cover, and the sealing ring is pre-sleeved in the groove. During installation, the rear shell presses the sealing ring in the groove of the front cover end face. This structure makes the front cover form different thicknesses at the position where the sealing ring is installed, resulting in a sudden change in the local thickness of the front cover of the controller. This kind of structure will affect the injection molding effect of the shell. The forming effect of the front cover is usually very poor at the place where the thickness suddenly changes, and local depressions and deformations are likely to appear on the outer surface. Usually, a very thick layer of paint needs to be sprayed additionally after injection molding to repair the outer surface of the front cover. In this way, the manufacturing cost will increase, and the repair effect is not good, and the appearance defects of the product cannot be completely solved. Summary of the Utility Model

[0003] In order to solve the technical problems existing in the prior art to a certain extent as much as possible, the utility model provides a controller with a waterproof structure and pool equipment, which can not only ensure the waterproof performance of the pool equipment controller, but also be beneficial to ensuring the aesthetics of the outer surface of the pool equipment controller.

[0004] A controller with a waterproof structure of the utility model includes an installation base and a protective cover sleeved on the installation base. A circuit module fixed on the installation base is arranged in the inner cavity of the protective cover, and a sealing ring for sealing the inner cavity of the protective cover is arranged in the gap between the installation base and the protective cover;

[0005] A circular inner step is formed on the inner wall of the cover opening of the protective cover, and the installation base is sleeved in the circular inner step;

[0006] An inclined extrusion surface facing the outer wall of the installation base is formed at the corner of the circular inner step;

[0007] The sealing ring is hermetically squeezed between the outer wall of the mounting base and the inclined squeezing surface of the annular inner step within the cover opening of the protective cover.

[0008] For a controller with a waterproof structure according to the present invention, an annular outer step is integrally formed on the bottom outer wall of the mounting base;

[0009] The sealing ring is sleeved on the annular outer step;

[0010] The corner of the annular outer step faces the inclined squeezing surface of the annular inner step and jointly seals and squeezes the sealing ring with the inclined squeezing surface.

[0011] For a controller with a waterproof structure according to the present invention, the annular outer step is sleeved within the annular inner step and is flush with the step end surface of the annular inner step.

[0012] For a controller with a waterproof structure according to the present invention, the shape of the corner of the annular outer step is adapted to the outer wall of the sealing ring.

[0013] For a controller with a waterproof structure according to the present invention, the cross-section of the sealing ring is square, and the corner of the annular outer step is a right angle that fits the shape of the outer wall of the sealing ring.

[0014] For a controller with a waterproof structure according to the present invention, the cross-section of the sealing ring is circular, and the corner of the annular outer step is a rounded corner that fits the shape of the outer wall of the sealing ring.

[0015] For a controller with a waterproof structure according to the present invention, a gap is formed between the inner wall of the protective cover at the part adjacent to the inclined squeezing surface and the outer wall surface of the mounting base.

[0016] For a controller with a waterproof structure according to the present invention, a snap hole and an inverted buckle are respectively formed on the mounting base and the protective cover;

[0017] The snap hole is opened on the side wall of the mounting base, and the inverted buckle and the inclined squeezing surface are formed on the same side wall of the protective cover;

[0018] Wherein, when the mounting base is sleeved within the annular inner step, the snap hole and the inverted buckle are snap-connected to each other and the inverted buckle and the snap hole are in clearance fit with each other.

[0019] For a controller with a waterproof structure according to the present invention, when the mounting base is sleeved within the annular inner step, the inverted buckle and the step surface of the annular outer step jointly squeeze the sealing ring from opposite sides of the sealing ring.

[0020] The present utility model also provides a pool device, the structure of which includes a controller with a waterproof structure as described above.

[0021] For a controller with a waterproof structure of the present utility model, firstly, a ring-shaped inner step is integrally formed on the inner wall of the cover opening of the protective cover of the controller. During installation, the mounting base of the controller is sleeved inside the ring-shaped inner step. Secondly, an inclined extrusion surface facing the outer wall of the mounting base is formed at the corner of the ring-shaped inner step. After installation, the sealing ring is hermetically squeezed between the outer wall of the mounting base and the inclined extrusion surface of the ring-shaped inner step inside the cover opening of the protective cover, thereby achieving the sealing effect of the controller. It can be understood that in this design scheme, in order to avoid a sudden change in the local thickness of the side wall of the protective cover, the ring-shaped inner step on the protective cover for pressing the sealing ring is structurally optimized, and the corner of the ring-shaped inner step is set as an inclined extrusion surface, making the corner position of the ring-shaped inner step transition more smoothly, avoiding a sudden change in thickness at the corner position of the ring-shaped inner step, so that the thickness of the side wall of the protective cover at the end of the cover opening can be as uniform as possible, preventing local depression and deformation on the surface of the controller housing after injection molding due to uneven thickness, thereby avoiding affecting the injection molding effect of the controller housing and being beneficial to ensuring the aesthetics of the surface of the pool device controller housing. In addition, after the controller is installed, its mounting base is sleeved inside the ring-shaped inner step of the protective cover, which is equivalent to completely inserting the mounting base of the controller into the inner cavity of the protective cover. The side surface of the mounting base of the controller can then be completely blocked by the protective cover, and at the same time, the sealing ring can also be blocked inside the inner cavity of the protective cover. Therefore, from the outside, only the surface of the protective cover of the controller can be seen. Thus, this structure can avoid obvious gaps remaining on the outer surface of the installed controller and avoid affecting the aesthetics of the product. Therefore, the technical solution of the present utility model can not only ensure the waterproof performance of the pool device controller, but also be beneficial to ensuring the aesthetics of the surface of the pool device controller housing.

[0041] As Figures 3 to 10 shown, a controller with a waterproof structure in this embodiment includes an installation base 1, a protective cover 2, and a circuit module 3 for installing electrical components. Both the installation base 1 and the protective cover 2 are plastic parts and can be integrally formed by the injection molding process of an injection mold. After the circuit module 3 is fixedly installed on the installation base 1, the protective cover 2 is sleeved with the installation base 1 so that the circuit module 3 can be accommodated in the inner cavity of the protective cover 2, and the inner cavity of the protective cover 2 is used to protect the circuit module 3. In addition, a sealing ring 4 is provided in the gap between the installation base 1 and the protective cover 2, and the inner cavity of the protective cover 2 is sealed by the sealing ring 4, so the sealing performance of the inner cavity of the protective cover 2 can be ensured, and it is ensured that the circuit module 3 in the inner cavity of the protective cover 2 is not easily damaged by water. In addition, in this embodiment, a ring-shaped inner step 21 is formed on the inner wall of the cover opening of the protective cover 2. When the protective cover 2 is sleeved with the installation base 1, the installation base 1 is sleeved in the ring-shaped inner step 21 of the protective cover 2. Regarding the structure of the ring-shaped inner step 21, an inclined extrusion surface 22 facing the outer wall of the installation base 1 is integrally formed at the corner of the ring-shaped inner step 21, and the sealing ring 4 is sealed and extruded between the outer wall of the installation base 1 and the inclined extrusion surface 22 of the ring-shaped inner step 21 in the cover opening of the protective cover 2.

[0042] In the structural solution of this embodiment, first, an annular inner step 21 is integrally formed on the inner wall of the cover opening of the protective cover 2 of the controller. During installation, the mounting base 1 of the controller is sleeved inside the annular inner step 21. Secondly, an inclined extrusion surface 22 facing the outer wall of the mounting base 1 is formed at the corner of the annular inner step 21. After the installation is completed, the sealing ring 4 is hermetically squeezed between the outer wall of the mounting base 1 and the inclined extrusion surface 22 of the annular inner step 21 inside the cover opening of the protective cover 2, thereby achieving the sealing effect of the controller. It can be understood that in this design solution, in order to avoid a sudden change in the local thickness of the side wall of the protective cover 2, the annular inner step 21 on the protective cover 2 for pressing the sealing ring 4 is structurally optimized. The corner of the annular inner step 21 is set as the inclined extrusion surface 22, so that the corner position of the annular inner step 21 has a smoother transition, avoiding a sudden change in thickness at the corner position of the annular inner step 21, making the thickness of the side wall of the protective cover 2 at the end of the cover opening as uniform as possible, preventing local depression and deformation on the surface of the controller housing after injection molding due to uneven thickness, and thus avoiding affecting the injection molding effect of the controller housing, which is beneficial to ensuring the aesthetics of the surface of the pool equipment controller housing. In addition, after the controller is installed, its mounting base 1 is sleeved inside the annular inner step 21 of the protective cover 2, which is equivalent to completely inserting the mounting base 1 of the controller into the inner cavity of the protective cover 2. The side surface of the mounting base 1 of the controller can be completely blocked by the protective cover 2, and at the same time, the sealing ring 4 can also be blocked inside the inner cavity of the protective cover 2. Therefore, from the outside, only the surface of the protective cover 2 of the controller can be seen. Therefore, this structure can avoid obvious gaps on the outer surface of the installed controller, avoiding affecting the aesthetics of the product. Therefore, the technical solution of the present utility model can not only ensure the waterproof performance of the pool equipment controller, but also be beneficial to ensuring the aesthetics of the surface of the pool equipment controller housing.

[0043] In one embodiment, further, an annular outer step 11 is integrally formed on the bottom outer wall of the mounting base 1. During assembly, the sealing ring 4 is pre-sleeved on the annular outer step 11. The corner of the annular outer step 11 of the mounting base 1 is a right-angle corner, and this right-angle corner faces the inclined extrusion surface 22 of the annular inner step 21 of the protective cover 2, and the corner of the annular outer step 11 and the inclined extrusion surface 22 of the annular inner step 21 jointly seal and squeeze the sealing ring 4. The technical effect of this structure is that the annular outer step 11 can be used to clamp the sealing ring 4. Under the support of the annular outer step 11, it is convenient to install and fix the sealing ring 4 on the mounting base 1. Finally, it can ensure that the inclined extrusion surface 22 of the annular inner step 21 of the protective cover 2 can stably seal and press the sealing ring 4, ensuring the waterproof sealing of the controller.

[0044] In one embodiment, preferably, the annular outer step 11 is sleeved inside the annular inner step 21. After the two are sleeved with each other, the step end faces of the annular outer step 11 and the annular inner step 21 are flush with each other, so as to ensure that the bottom of the mounting base 1 does not protrude from the cover opening of the protective cover 2 after the controller is installed.

[0045] In one embodiment, the corner shape of the annular outer step 11 is adapted to the outer wall of the sealing ring 4. Specifically, in this embodiment, the cross-section of the sealing ring 4 is square, and the corner of the annular outer step 11 is a right angle, so as to fit the shape of the outer wall of the sealing ring 4. Therefore, when the sealing ring 4 is sleeved on the annular outer step 11, the annular outer step 11 can fit more closely to the outer wall surface of the sealing ring 4, which is beneficial to improving the sealing performance of the sealing ring 4 between the mounting base 1 and the protective cover 2. Optionally, as an alternative to the above, the cross-section of the sealing ring 4 in this embodiment can also be set as circular. Correspondingly, the corner shape of the annular outer step 11 can be set as a rounded corner to fit the shape of the outer wall of the sealing ring 4.

[0046] As a preferred solution of this embodiment, a gap 5 is formed between the inner wall of the protective cover 2 at the part adjacent to the inclined extrusion surface 22 and the outer wall surface of the mounting base 1. In this embodiment, the gap 5 is formed on the upper and lower sides of the inclined extrusion surface 22. Therefore, when the inclined extrusion surface 22 extrudes the sealing ring 4, the deformed sealing ring 4 under pressure can be respectively squeezed into the gaps 5 on the upper and lower sides. This structure is beneficial to further improving the waterproof sealing effect between the mounting base 1 and the protective cover 2.

[0047] In one embodiment, in combination with Figure 11 As shown, a horizontally extending buckling hole 12 is integrally formed on the side wall of the mounting base 1. Correspondingly, an inverted buckle 23 is integrally formed on the inner wall of the protective cover 2, and the inverted buckle 23 and the inclined extrusion surface 22 are formed on the same side wall of the protective cover 2. When the mounting base 1 is sleeved inside the annular inner step 21, the buckling hole 12 and the inverted buckle 23 are buckled with each other, so that the mutual connection between the mounting base 1 and the protective cover 2 can be realized simply and efficiently. In addition, the buckling hole 12 and the inverted buckle 23 are in clearance fit with each other.

[0048] As a preferred solution of this embodiment, in combination with Figure 11As shown, when the mounting base 1 is sleeved in the annular inner step 21, the undercut 23 and the step surface of the annular outer step 11 jointly squeeze the sealing ring 4 from the opposite sides of the sealing ring 4. That is to say, after the mounting base 1 of the controller is connected to the protective cover 2, the sealing ring 4 is squeezed in the left and right directions by the side surface of the annular outer step 11 and the inclined squeezing surface 22 of the annular inner step 21. In addition, in the up and down directions, the sealing ring 4 can also be squeezed by the undercut 23 and the step surface of the annular outer step 11. Therefore, the sealing ring 4 installed between the mounting base 1 of the controller and the protective cover 2 can be squeezed more fully. This structure can also help to further enhance the waterproof sealing effect between the mounting base 1 and the protective cover 2.

[0049] Based on the above, this embodiment also implements a swimming pool equipment, whose structure includes the controller with waterproof structure of the utility model, thereby effectively improving the local waterproof sealing of the swimming pool equipment and avoiding appearance defects of the controller shell of the swimming pool equipment.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
