The casing seat 91 has an opening 911, an inflow portion 912 and an outflow portion 913 communicating with the inside, the drainage portion 92 and the driving portion 93 can be placed into the casing seat 91 through the opening 911, and the cover plate 94 is detachably combined with the casing seat 91 to close the opening 911. When the driving portion 93 operates, the drainage portion 92 can draw the working fluid from the inflow portion 912, and the drainage portion 92 can discharge the working fluid to the outflow portion 913. In addition, the liquid driving assembly 9 may further have a sensor 95 electrically connected to a power supply portion 96, the power supply portion 96 is further electrically connected to the driving portion 93, and the sensor 95 may be installed in the housing 91 and used for sensing whether the cover 94 closes the opening 911. Thus, if the sensing result of the sensor 95 is negative, the power supply of the power supply part 96 to the driving part 93 is cut off, so that the driving part 93 can automatically stop driving the working fluid to flow when the cover plate 94 is opened, and the effects of reducing the loss caused by the splashing of the working fluid, improving the operation convenience and the like are achieved; in addition, the influence of current or voltage surge can be avoided, and the hot plug function is supported under the condition that the electronic device continuously operates, so that the use convenience is improved.

However, in the above-mentioned liquid driving assembly 9, since the sensor 95 is triggered when the cover plate 94 is close to the closed position but not completely closed, the driving portion 93 does not start to operate after the cover plate 94 is closed accurately; similarly, the cover 94 will trigger the sensor 95 when it is slightly opened, and thus the power supply 96 will be cut off to the driving portion 93, which results in that the driving portion 93 will not stop operating before the cover is opened. Therefore, the liquid driving assembly 9 still has a small amount of working liquid splashing during use, and therefore, improvement is necessary.

Detailed Description

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below; in the drawings, the same reference numerals denote the same elements, and the description thereof will be omitted.

Please refer to fig. 2, which shows a first embodiment of the liquid driving assembly of the present invention, including a housing 1, a pump 2, a sealing cover 3, a pre-opening/closing assembly 4, and an electric control module 5, wherein the sealing cover 3 seals the pump 2 in the housing 1, and the pre-opening/closing assembly 4 is opened or closed to enable the electric control module 5 to switch the power supply state of the pump 2 accordingly.

Referring to fig. 2 and 4, the housing base 1 has an opening 11 and a chamber S therein. The chamber S can accommodate the pump 2, and the housing 1 has an inflow portion 12 and an outflow portion 13, the inflow portion 12 and the outflow portion 13 are respectively communicated with the chamber S, so that the pump 2 can draw a working fluid from the inflow portion 12 and pump the working fluid from the outflow portion 13. The present invention is not limited to the shape of the housing 1, for example, the housing 1 of the present embodiment may have a bottom plate 1a and a ring wall 1b, the ring wall 1b is connected to the bottom plate 1a to form the chamber S, and the opening 11 may be disposed opposite to the bottom plate 1 a. The inflow portion 12 and the outflow portion 13 can be disposed on the annular wall 1b of the housing base 1, and can be selectively disposed on the same side or different sides of the annular wall 1b according to the requirement of pipeline configuration. In addition, the inflow portion 12 and the outflow portion 13 of the present embodiment may be in a joint shape to connect the pipes, but the present invention is not limited to this shape. Additionally, the inner wall W of the housing base 1 may also form a plurality of shoulders 14 for positioning the components housed inside the housing base 1.

The pump 2 of the present embodiment may have a body 21 and an impeller 22, wherein the impeller 22 is connected to the body 21, and when the stator set in the body 21 is powered, the impeller 22 can be driven to rotate. In this embodiment, the pump 2 can abut against one of the shoulders 14 of the inner wall W of the housing base 1 from the lower edge of the body 21, so that the impeller 22 does not contact the inner wall W and the bottom surface of the housing base 1 when rotating below the body 21. In addition, referring to fig. 3, the body 21 may have a flow channel 211 communicating with the inflow portion 12 of the housing 1 for guiding the working fluid to the impeller 22, and a rotating space of the impeller 22 communicates with the outflow portion 13 of the housing 1, so that the working fluid can be driven by the impeller 22 and flow out of the housing 1 through the outflow portion 13.

Referring to fig. 2 and 4 again, the sealing cover 3 is combined with the housing base 1 and used for sealing the chamber S. At least one rubber ring R can be arranged between the sealing cover 3 and the inner wall W of the shell seat 1, and the sealing cover 3 presses against the rubber ring R to deform so as to tightly seal the inner wall W of the shell seat 1 and seal the containing chamber S. In this embodiment, the sealing cover 3 has a main body 31, and may further have an outer expanding portion 32 connected to the outer circumference of the main body 31. When the sealing cap 3 of the present embodiment is placed in the housing base 1, the bottom end of the main body 31 can press against the top end of the body 21 of the pump 2, so that the pump 2 can be stably positioned at a predetermined position in the housing base 1, and the outward expanding portion 32 abuts against the other shoulder 14 of the inner wall W of the housing base 1. Thus, the rubber ring R can be located between an outer ring peripheral surface 321 of the outer expanding portion 32 and the inner wall W of the housing base 1; alternatively, the flared ring portion 32 may have a ring bottom surface 322 abutting against the shoulder portion 14, and the rubber ring R may be optionally disposed between the ring bottom surface 322 of the flared ring portion 32 and the shoulder portion 14. Preferably, at least one rubber ring R is disposed at each of the two positions to further improve the liquid tightness between the sealing cover 3 and the housing base 1.

Referring to fig. 2 and 5, the sealing cover 3 of the present embodiment may further include a concave portion 33 and a handle 34, the concave portion 33 is located at the center of the top end of the main body 31, the handle 34 may be connected to the main body 31 and cross over the concave portion 33, so that a user can insert a finger into the concave portion 33 and hook the handle 34 to pull the sealing cover 3 out of the housing 1; or the handle 34 is lifted to put the sealing cover 3 into the interior of the housing base 1. Wherein, the top surface T of the handle 34 can be made to be slightly convex, such as convex arc shape, and the central position has a most convex part P; thus, when the pre-opening/closing assembly 4 is in the closed state, the most protruding portion P of the handle 34 can be pressed downward, so that the downward pressure can be uniformly applied to the sealing cover 3, thereby improving the uniformity of the sealing cover 3 sealing the chamber S.

The pre-opening/closing assembly 4 is adjacent to the opening 11 of the housing base 1, and can be in an opening state or a closing state relative to the opening 11. The pre-opening/closing element 4 of this embodiment may have a cover 41, the cover 41 is pivotally connected to the housing 1, and when the pre-opening/closing element 4 is in a closed state (as shown in fig. 5), the cover 41 may cover the opening 11 and press against the sealing cover 3. Wherein, in order to ensure that the outer cover 41 can be pressed against the casing base 1 and have the effect of enhancing leakage prevention, a rubber ring R can be further arranged between the outer cover 41 and the top surface of the casing base 1, the rubber ring R can be arranged around the opening 11, and the rubber ring R is deformed under pressure when the pre-opening and closing assembly 4 is in a closed state. In order to maintain the state of the cover 41 pressing against the sealing cover 3, the pre-opening/closing assembly 4 of the present embodiment may further have an elastic pressing component 42, and the elastic pressing component 42 may also be pivotally connected to the housing base 1; referring to fig. 4, when the pre-opening/closing assembly 4 is in a closed state, the elastic pressing member 42 can be pressed against the outer cover 41, so that the outer cover 41 keeps pressing against the sealing cover 3. It should be noted that in other embodiments, the pre-opening/closing element 4 may not be provided with the elastic buckling member 42 if the cover 41 is closed to maintain the pressing force against the sealing cover 3.

Referring to fig. 2 and 3, the present invention is not limited to the shape of the elastic pressing member 42; for example, the elastic buckling member 42 of the present embodiment may have a pivot section 42a connected to a fastening section 42b, and the pivot section 42a and the fastening section 42b may form an L-shaped structure together. The housing 1 may have two opposite pivoting portions 15, one of the two pivoting portions 15 is for pivoting the outer cover 41, the other pivoting portion 15 is for pivoting the pivoting section 42a of the elastic buckling member 42, and the housing 1 may further extend to form a protruding lug 16 outside the pivoting portion 15 for pivoting the outer cover 41. On the other hand, the elastic buckling member 42 can make a part of the pivot section 42a protrude to form a pressing portion 421, and the protruding direction of the pressing portion 421 is the same as the extending direction of the abutting section 42 b. Thus, when the pre-opening/closing assembly 4 is in an open state, the abutting section 42b of the elastic buckling member 42 and the pressing portion 421 can be in an upright state as shown in fig. 2; when the pre-opening/closing assembly 4 is closed, the abutting section 42b of the elastic pressing buckle 42 and the pressing portion 421 can be in a flat shape as shown in fig. 3, and the pressing portion 421 presses against a tongue portion 411 of the outer cover 41, and the abutting section 42b is substantially opposite to the outer side of the housing base 1 and elastically deformed to abut against the lower edge of the lug 16 of the housing base 1. Additionally, the elastic buckling member 42 may further form an outer extension 422 at the free end of the abutting section 42b for the user to press, and the embodiment selects to form the outer extension 422 as a hook, but not limited thereto.

Referring to fig. 2 and 5, the electronic control module 5 has a power supply portion 51 directly or indirectly electrically connected to a sensor 52 and the pump 2, the sensor 52 is used for sensing whether the pre-opening/closing element 4 is in an open state or a closed state, and when the pre-opening/closing element 4 is in the closed state, the power supply portion 51 supplies power to the pump 2; when the pre-open/close component 4 is in the open state, the power supply portion 51 cuts off the power of the pump 2. The power supply state of the power supply part 51 to the pump 2 is switched by the sensing result of the sensor 52, so that the damage of an electrical module of the electronic device caused by the generation of current or voltage surge when the electrical connection relationship between the pump 2 and the power supply part 51 is suddenly removed can be avoided.

For example, but not limiting of, when the power supply part 51 is selected to be provided to the cover 41, the transmission of power needs to be re-transmitted to the pump 2 through the sealing cover 3; for example, the power supply portion 51 may be, for example, a plurality of contacts disposed on the inner surface of the cover 41, the plurality of contacts may be electrically connected to an external power source, the top surface of the sealing cover 3 is further provided with an electrical transmission port 35, and when the cover 41 is closed, the power supply portion 51 may be connected to and electrically connect the electrical transmission port 35. In addition, since the sealing cover 3 and the pump 2 of the present embodiment are two separable components, a structure that needs to transmit power between the sealing cover 3 and the pump 2 is also applicable, for example, the power can be transmitted by using the aforementioned contact conduction method, or the power can be transmitted by using the plugging connection method of the male and female connectors, and the invention is not limited thereto.

The sensor 52 may be, for example, a micro Switch (Limit Switch), a Photo Interrupter (Photo Interrupter), or a Proximity Switch (Proximity Switch). In this embodiment, the sensor 52 can be selectively installed on the top edge of the annular wall 1b of the housing base 1, and the sensor 52 can be triggered by the outer cover 41 to sense the opening or closing of the outer cover 41, so that the power supply portion 51 powers off or supplies power to the pump 2.

Referring to fig. 3 and 5, when the pre-open/close assembly 4 is in a closed state, the power supply portion 51 supplies power to the pump 2, and the operation of the pump 2 enables the working fluid to flow into the accommodating chamber S from the inflow portion 12 and then flow out of the housing base 1 through the outflow portion 13, so that the working fluid continuously and circularly flows.

Referring to fig. 3, when the pump 2 needs to be replaced due to a failure (e.g. failure or too loud operation noise), a user can press the outer extension 422 of the elastic pressing buckle 42 to elastically deform the abutting section 42b of the elastic pressing buckle 42 to disengage from the lower edge of the lug 16 of the housing 1. Then, as shown in fig. 2, the elastic pressing buckle 42 is pivoted to make the abutting section 42b of the elastic pressing buckle 42 and the pressing portion 421 form an upright shape; thus, the pressing portion 421 of the elastic pressing member 42 will no longer press against the tongue portion 411 of the outer cover 41, so that the outer cover 41 can pivot relative to the housing 1 without being limited by the elastic pressing member 42.

Referring to fig. 6, during the process of opening the cover 41, the sensor 52 can be triggered, so that the power supply portion 51 cuts off the power of the pump 2, and the pump 2 stops driving the working fluid. Therefore, the sealing cover 3 still maintains the sealing of the chamber S after the pump 2 stops operating, so that the working fluid does not spill during the process of switching the pre-opening/closing assembly 4 from the closed state to the open state. Then, the user can take out the sealing cover 3 and the pump 2 to be replaced from the housing 1, and then put in and assemble a new pump 2.

Referring to fig. 5, after a new pump 2 is installed in the chamber S of the housing base 1, the sealing cover 3 is assembled to the predetermined position in the housing base 1 to seal the chamber S again; at this time, the pre-open/close component 4 is still in the open state, so the power supply portion 51 does not supply power to the pump 2. Until the cover 41 pivots to close or completely close with respect to the housing base 1 again, the sensor 52 can be triggered again, so that the power supply portion 51 starts to supply power to the pump 2 to drive the working fluid. Therefore, the sealing cover 3 seals the chamber S before the pump 2 starts to operate, so that the problem of loss caused by working fluid splashing can be avoided in the process of replacing the pump 2.

Referring to fig. 7 and 8, a second embodiment of the liquid driving assembly of the present invention is shown, which is substantially the same as the first embodiment, and mainly differs therefrom in that: the embodiment chooses to make the sensor 52 triggered by the elastic buckling member 42, not by the cover 41.

In detail, in the present embodiment, the sensor 52 can be selectively disposed on the lug 16 of the housing base 1, so that the sensor 52 can be triggered when the abutting section 42b of the elastic buckling member 42 abuts on the lug 16 or leaves the lug 16, that is, the sensor 52 is triggered only in the first or last step of replacing the pump 2, so that the effect of powering off the pump 2 in advance or powering on the pump 2 after being delayed is more obvious; meanwhile, it can also be used to check if the elastic buckling member 42 is installed and fixed, if the elastic buckling member 42 is not installed and fixed, the pump 2 cannot be powered. In other embodiments, the sensor 52 can be triggered by other parts of the elastic buckling member 42, and those skilled in the art can modify the sensor according to the usage requirement, and the invention is not limited to the form disclosed in the drawings. On the other hand, the present embodiment can also select to integrally connect or combine the sealing cover 3 and the pump 2, so that the pump 2 can be taken out together when the sealing cover 3 is taken out, and it is more convenient to set a fixed electrical connection relationship between the sealing cover 3 and the pump 2, so as to reduce the probability of electrical connection errors.

Referring to fig. 9 and 10, a third embodiment of the liquid driving assembly of the present invention is shown, which is substantially the same as the first embodiment, and mainly differs therefrom in that: in the present embodiment, the power supply portion 51 is selectively provided in the housing 1.

In detail, the power supply portion 51 may be disposed on the annular wall 1b of the housing base 1, for example, mounted together with the sensor 52 at the top edge of the annular wall 1 b. The electronic control module 5 may further have a first electrical connection port 53 located on the inner wall W of the housing 1 and electrically connected to the power supply portion 51; the pump 2 can have a second electrical connection port 23, and after the pump 2 is placed inside the housing base 1, the second electrical connection port 23 can be connected and conducted with the first electrical connection port 53, so that the power supply portion 51 can indirectly supply power to the pump 2 through the first electrical connection port 53 and the second electrical connection port 23.

In this embodiment, the pump 2 may further have a housing 24, the housing 24 may be integrally connected to the body 31 of the sealing cover 3, and the body 21 and the impeller 22 are accommodated in the housing 24. The casing 24 may further have two flow channels 241, one end of each flow channel 241 is connected to the space inside the casing 24 for the rotation of the impeller 22, and the other end is connected to the outside of the casing 24; after the pump 2 is placed in the housing 1, the two flow channels 241 are respectively connected to the inlet portion 12 and the outlet portion 13 of the housing 1. In addition, the second electrical connection port 23 can be selectively disposed on the outer surface of the housing 24 so as to be connected and conducted with the first electrical connection port 53.

On the other hand, the cover 41 of the present embodiment can press the sealing cover 3 when covering, and the tongue 411 of the cover 41 can trigger the sensor 52, so the middle portion of the cover 41 can be hollowed out to save material and reduce the weight of the whole liquid driving assembly.
