For a shell-less water purifier, the mount assembly 500 can be provided independently or connected to the cartridge mount. Mount assembly 500 may include a housing 600. The seat body 600 may be provided with a seat water inlet joint 621 and a seat water outlet joint 622. When the pump assembly 100 is mounted to the mount assembly 500, the mount inlet 621 may be connected with the housing inlet 211 and the mount outlet 622 may be connected with the housing outlet 212. The outer wall of the base body 600 is provided with a water inlet 631 and a water outlet 632. The water inlet 631 and the water outlet 632 may be provided at any suitable positions on the outer wall of the housing body 600. The water inlet 631 may communicate with the seat water inlet connector 621 inside the seat body 600. The water outlet 632 may communicate with the seat outlet connector 622 inside the seat body 600. In this way, the water inlet 631 and the water outlet 632 are formed in the outer wall of the seat body 600, so that the water path between the mounting seat assembly 500 and the outside is communicated.

By connecting the pump assembly 100 to the mount assembly 500, a completed waterway may be formed within the booster device. When the booster pump 300 is powered on, water may enter the booster pump 300 through the water inlet 631, the seat water inlet 621, the housing water inlet 211, and the pump water inlet 310 in sequence under the action of the booster pump 300. After being pressurized by the booster pump 300, the water flows out of the pressurizing device through the water outlet 320 of the pump, the water outlet connector 212 of the shell, the water outlet connector 622 of the seat and the water outlet 632 in sequence. In this way, the pressurising means may provide high pressure water to the reverse osmosis filter element downstream thereof.

By providing the pump assembly 100 and the mount assembly 500, quick mounting and dismounting of the booster pump 300 is achieved. During assembly, the pump assembly 100 is directly mounted on the mounting block assembly 500, and thus, the pump assembly is assembled on site even without leaving the factory, thereby providing a possibility of reducing the packaging and transportation costs. The pump assembly 100 is directly mounted on the mounting seat assembly 500, so that the booster pump 300 is fixed, and the water path communication with the reverse osmosis filter element can be realized. In service replacement, the pump assembly 100 is simply removed from the mount assembly 500 and replaced with a new pump assembly 100. Therefore, the utility model provides a pump assembly 100 can realize the quick installation and the dismantlement of booster pump, greatly reduced installation and time and the process of dismantling to reduce the cost of installation and dismantlement. Meanwhile, because of the difference of parameters such as flow in water purifiers of different models, the models of the booster pumps are different, so that the structures and positions of the booster pumps, the interfaces thereof and the like are different. By properly configuring the housing 200, different types of booster pumps can use housings 200 having the same interface size and external dimensions. Like this, in the purifier of difference, can be equipped with the same space and the same mount pad subassembly 500 for the booster pump to realize the standardization of booster pump, reduced mould quantity, reduce cost.

As shown in fig. 3-4, the holder body 600 may preferably have a slot 610. The socket 610 may be for receiving at least a portion of the head of the housing 200. The bottom of the socket 610 may be provided with a seat water inlet 621 and a seat water outlet 622. By connecting the socket 610 with the head, the degree of freedom of the pump assembly 100 can be restricted to some extent, thereby enabling the pump assembly 100 to be more firmly fixed to the housing 600. And, fix through slot 610 has simple structure, advantage such as the processing cost is low.

Preferably, the housing 200 may be provided with a locking portion. The locking portion may be used to lock the pump assembly 100 to the mount assembly 500. The locking portion may take any of a variety of configurations, or various types of locking portions known in the art or that may occur in the future.

In this embodiment, a lock engagement portion may be provided on the mount assembly 500. The locking mating portion may be used to mate with a locking portion to lock the pump assembly 100 to the mount assembly 500. The locking mating portion may take any of a variety of configurations, or any of a variety of types of locking mating portions known in the art or that may occur in the future, so long as they cooperate to lock the pump assembly 100 to the mount assembly 500. Through setting up locking portion and locking cooperation portion, can make pump assembly 100 lock to mount pad subassembly 500, ensure that pump assembly 100 can not break away from mount pad subassembly 500 in the use, improve supercharging's stability.

In a first preferred embodiment, as shown in fig. 3-4, the locking portion may include a locking projection 410 on an outer sidewall of the head portion. The locking lugs 410 may be provided at any suitable location on the outer side wall of the head. The number of locking projections 410 may be arbitrary. Preferably, the locking projections 410 are plural in number and uniformly distributed along the circumferential direction of the outer sidewall of the head.

In this embodiment, the mount assembly 500 may further include a rotating member 710. The rotary member 710 may be rotatably disposed on the holder body 600 between a locking position and an unlocking position around the insertion groove 610. The rotating member 710 can be rotated between a locked position and an unlocked position by manual rotation. Alternatively, the rotating member 710 may be rotated between the locking position and the unlocking position by a motor or the like. The inner side wall of the rotating member 710 may be provided with a lock coupling protrusion 720. The lock mating protrusion 720 may be spaced apart from the bottom of the socket 610. The spaced apart spaces may be used to accommodate the locking lugs 410. When the rotational member 710 is in the unlocked position, the lock mating tab 720 may be offset from the lock tab 410 in a circumferential direction of the socket 610. In this way, the pump assembly 100 can be mounted to the housing 600 or pulled out from the housing 600 in the axial direction thereof. When the rotational member 710 is in the locked position, the lock mating protrusion 720 may be aligned with the lock protrusion 410 in a circumferential direction of the socket 610. The lock protrusion 410 may be caught in a space where the lock fitting protrusion 720 is spaced apart from the bottom of the socket 610. At this time, the locking mating protrusion 720 may be completely aligned with the locking protrusion 410, and the locking mating protrusion 720 may also be partially aligned with the locking protrusion 410, as long as the locking protrusion 410 can be caught in the spaced-apart space. In this way, the pump assembly 100 is prevented from being pulled out, thereby achieving locking of the pump assembly 100 to the housing 600.

By providing the locking protrusion 410 and the locking mating protrusion 720, the pump assembly 100 can be directly mounted on the housing 600, and the pump assembly 100 can be locked and unlocked by rotating the rotating member 710, so that the pump assembly 100 is prevented from being separated from the housing 600 during use, and the stability of the supercharging device is improved. Furthermore, due to the in-line mounting, water cannot flow in the waterway between the pump assembly 100 and the mount assembly 500.

Further, as shown in fig. 3-4, the locking projection 410 may have a locking flat 411 and an ejection ramp 412. The locking flat 411 and the push slope 412 may be located at both sides of the locking protrusion 410. The locking plane 411 may face the rear of the housing 200. The locking plane 411 may extend in a circumferential direction of the housing 200. The push slope 412 is inclined at a predetermined angle with respect to the circumferential direction of the housing 200. The predetermined angle can be selected by a person skilled in the art according to the actual situation.

In this embodiment, the lock engagement projection 720 may have a lock engagement flat 721 and a push engagement ramp 722. The lock engagement surface 721 may face the bottom of the socket 610. The lock engagement flat 721 may be perpendicular to the axial direction of the socket 610. The push engagement ramp 722 may face and be parallel to the push ramp 412. The push fit ramps 722 may face the opening of the slot 610. The opening of the slot 610 and the bottom of the slot 610 may be disposed opposite each other. The push engagement ramp 722 may be inclined at the predetermined angle in a direction from the locked position to the unlocked position (i.e., clockwise as shown by arrow a in fig. 3-4) toward a direction opposite to the mounting direction of the pump assembly 100 (i.e., an upward direction) such that the push engagement ramp 722 is disposed in parallel with the push ramp 412.

When the pump assembly 100 is not yet installed in the socket 610 of the mount assembly 500, the rotary member 710 is in the locked position, and as the pump assembly 100 is progressively installed in the axial direction into the socket 610, the ejection ramps 412 may compress the ejection mating ramps 722, thereby driving the rotary member 710 to rotate from the locked position to the unlocked position. When the rotational member 710 is in the unlocked position, the lock tabs 410 on the housing 200 can move past the lock mating tabs 720 into the space where the lock mating tabs 720 are spaced from the bottom of the socket 610. At this time, the rotating member 710 may be manually rotated or the rotating member 710 may be returned to the locking position by means of the returning member, whereby the pump assembly 100 may be locked to the housing 600.

Through the arrangement, when the pump assembly 100 is mounted in the slot 610, the rotating member 710 can rotate along with the slot, so that the operation steps can be reduced on the basis of realizing the locking of the pump assembly 100 to the seat body 600, and the man-machine interaction is better.

Preferably, as shown in fig. 3-4, the rotating member 710 may be ring-shaped. Preferably, the rotating member 710 may be coaxially disposed with the insertion groove 610. The lock fitting protrusions 720 may be distributed on the inner side wall of the rotational member 710. For the rotating member 710, the inner sidewall refers to its inner peripheral wall. Preferably, the number of the lock engagement projections 720 is plural and is uniformly distributed along the circumferential direction of the rotational member 710. Correspondingly, the number and the position of the locking protrusions 410 correspond to the locking fitting protrusions 720, that is, a plurality of locking protrusions 410 may be uniformly distributed on the outer circumferential wall of the head of the housing 200. With this arrangement, when the rotating member 710 is in the locked position, the head of the housing 200 is uniformly stressed and the pump assembly is securely locked.

In other embodiments not shown, the rotating member 710 may also be a non-annular structure, i.e., it is disposed around only a portion of the slot 610. For example, the rotating member 710 may also have any shape of a half-ring, a quarter-ring, an eighth-ring, etc.

Preferably, as shown in fig. 3-4, the mount assembly 500 may further include a lock sleeve 730. The lock sleeve 730 can be rotatably sleeved on the base body 600 around the slot 610. The lock sleeve 730 may be connected to the rotating member 710. The manner in which the sleeve 730 is coupled to the rotating member 710 may be arbitrary. In the embodiment shown in the figures, the inner side wall of the sleeve 730 may be provided with a projection 731. The outer side wall of the rotating member 710 may be provided with a groove 732. The coupling of the sleeve 730 to the rotating member 710 is achieved by snapping the projection 731 into the recess 732. In other embodiments not shown, the sleeve 730 may be connected to the rotational member 710 by welding, adhesive, or the like.

Through setting up lock sleeve 730, can effectively avoid falling into impurity such as dust on the rotating member 710, lead to the emergence of the circumstances such as rotatory card is dead, rotational speed unstability. Also, a user can be prevented from contacting the rotary member 710, and occurrence of a dangerous accident when the rotary member 710 rotates can be avoided. In addition, the lock sleeve 730 can surround the holder body 600 and the rotating member 710, so that the mount assembly 500 is neater in appearance.

Preferably, as shown in fig. 3 to 4, a guide member 651 may be provided on the outer circumferential wall of the holder body 600. The inner circumferential wall of the rotating member 710 may be provided with a guide groove 652. The guide groove 652 may extend in a circumferential direction of the insertion groove 610. The guide member 651 is slidably coupled to the guide groove 652.

By providing the guide member 651 and the guide groove 652, the rotary member 710 is not easily deviated from a desired trajectory during rotation, and the mount assembly 500 has good stability.

Preferably, as shown in fig. 3-4, the mount assembly 500 may further include a reset element 640. The restoring member 640 may be connected between the holder body 600 and the rotating member 710. Preferably, the restoring member 640 may be a spring.

As described above, during installation of the pump assembly 100, the lock engagement projection 720 on the rotating member 710 is pushed down the lock projection 410 on the housing 200 to the unlocked position, where the reset 640 can be in a compressed or extended large amount. When the pump assembly 100 is installed in place, i.e., the locking projections 410 move past the locking mating projections 720 and between the locking mating projections 720 and the bottom of the socket 610, the reset 640 may release its stored elastic potential energy to return the rotational member 710 to the locked position. At this time, the restoring member 640 may be in a naturally extended state, or compressed or stretched by a small amount.

By providing the reset member 640, the rotating member 710 can rotate to the locked position by itself when the pump assembly 100 is installed in place, thereby reducing the number of operation steps and providing better man-machine interaction.

In a second preferred embodiment, as shown in fig. 7, the locking portion may include a screw groove 420 located on an outer sidewall of the head portion of the pump assembly 100. The rotation catching groove 420 may extend in a circumferential direction of the head. One end of the rotary clamping groove 420 is closed and the other end is open. In the embodiment shown in the figures, the snap-on groove 420 may be formed by an L-shaped protrusion 430 provided on the head. In an embodiment not shown, card slot 420 may be formed in any other suitable manner. The lock mating portion may include a rotation detent protrusion 740.

The rotation-chucking protrusion 740 may extend in a circumferential direction of the socket 610. The rotation-locking protrusion 740 can be locked into the rotation-locking groove 420. Illustratively, two rotation-locking protrusions 740 may be disposed on an inner sidewall of the slot 610.

When the pump assembly 100 is installed, the L-shaped protrusion 430 on the pump assembly 100 can be aligned with the gap between the two rotation-locking protrusions 740, and when the pump assembly 100 is installed in place in the axial direction, the pump assembly 100 can be rotated such that the rotation-locking protrusions 740 enter the rotation-locking grooves 420 from the openings of the rotation-locking grooves 420, and the rotation-locking protrusions 740 are snapped into the rotation-locking grooves 420, thereby locking the pump assembly 100 to the mount assembly 500. When the pump assembly 100 is disassembled, rotating the pump assembly 100 can disengage the bayonet boss 740 from the bayonet slot 420, thereby allowing the pump assembly 100 to be unlocked from the mount assembly 500. The pump assembly 100 can then be pulled out in the axial direction.

Through setting up the knob 740 and the knob groove 420, can lock pump package 100 to mount pad subassembly 500 convenient and fast, can ensure that pump package 100 can not break away from pedestal 600 in the use, improve supercharging device's stability. In addition, the rotation clamping protrusion 740 and the rotation clamping groove 420 have simple structures and are easy to realize.

In the third preferred embodiment, as shown in fig. 8, the housing water inlet joint 211 and the housing water outlet joint 212 are each a rigid water pipe extending in the axial direction of the housing 200. The rigid water tube may extend from the head in a direction away from the housing 200. Correspondingly, the seat water inlet 621 and the seat water outlet 622 may also be rigid water pipes. The mount assembly 500 may also include a first quick connector 751 and a second quick connector 752. In a state where the pump assembly 100 is mounted to the mounting base assembly 500, the first quick connector 751 can be sleeved on the housing water inlet connector 211 and the base water inlet connector 621 for connecting the housing water inlet connector 211 and the base water inlet connector 621. The second quick connector 752 can be sleeved on the housing outlet connector 212 and the base outlet connector 622 for connecting the housing outlet connector 212 and the base outlet connector 622.

With this arrangement, the pump assembly 100 can be locked to the mount assembly 500, ensuring that the pump assembly 100 does not disengage from the mount assembly 500 during use, improving the stability of the booster device. In addition, the scheme has the advantages of simple structure, easiness in implementation and the like.

In a fourth preferred embodiment, as shown in fig. 9, the locking portion of the pump assembly 100 may include external threads provided on a head portion thereof, and the locking mating portion of the mount assembly 500 may further include external threads provided on an outer circumferential surface thereof. The pump assembly 100 and the mount assembly 500 may be connected by a threaded sleeve 900, and the threaded sleeve 900 may be internally threaded. The pump assembly 100 and the mount assembly 500 are locked by screwing the pump assembly 100 and the mount assembly 500 to the threaded sleeve 900.

The differences between the second to fourth embodiments and the first embodiment are described above, the same reference numerals are used for the same or similar components of the second to fourth embodiments as the first embodiment, and the detailed description of the same or similar components is omitted here for the sake of brevity.

Preferably, as shown in fig. 3-4, a water stop valve may be disposed on the seat inlet 621 and/or the seat outlet 622. The stop valve may be any of a variety of types known in the art or that may occur in the future. In the embodiment shown in the figures, a fourth water stop valve 780 may be provided on the seat outlet fitting 622. The fourth water stop valve 780 may include a fourth valve spool 781 and a fourth elastic member 782. A portion of the fourth valve spool 781 may protrude out of the seat outlet joint 622. With the pump assembly 100 mounted to the mount assembly 500, the fourth valve spool 781 may be pushed back in a direction within the seat outlet 622. At this time, the fourth elastic member 782 is compressed, and the fourth water stop valve 780 is turned on.

When the pump assembly 100 is not mounted to the mount assembly 500, the fourth resilient member 782 may be in a naturally extended state, or compressed a small amount. At this point the fourth water stop valve 780 is closed and water cannot flow out of the seat outlet fitting 622 out of the mount assembly 500. When the pump assembly 100 is mounted to the mount assembly 500, the pump assembly 100 compresses the fourth valve spool 781 such that the fourth valve spool 781 is pushed back in a direction into the seat outlet fitting 622. At this point, the fourth water stop valve 780 is open, and water can enter the mount assembly 500 through the mount outlet 622, forming a complete waterway.

Similar to the third water stop valve 770 and the fourth water stop valve 780, a water stop valve may be provided on the housing water inlet joint 211 and/or the housing water outlet joint 212. For example, a first water stop valve (not shown) may be disposed on the housing water inlet joint 211.

When the pump assembly 100 is not mounted to the mount assembly 500, the first resilient member may be in a naturally extended state, or compressed a small amount. At this point the first stop valve is closed and water cannot flow out of the pump assembly 100 through the housing inlet fitting 211. When the pump assembly 100 is mounted to the mount assembly 500, for example, a third spool on the mount assembly 500 will compress the first spool, causing the first spool to be pushed back in the direction of the housing water inlet 211. At this time, the first water stop valve is turned on, and water can enter the booster pump 300 through the shell water inlet joint 211 to form a complete water path. The first and second stop valves may be the same or different. A second water stop valve (not shown) may be provided on the housing outlet fitting 212. The third water stop valve 770, the fourth water stop valve 780, the first water stop valve and the second water stop valve may be the same or different.

By arranging the water stop valve on the shell water inlet joint 211 and/or the shell water outlet joint 212, after the pump assembly 100 is disassembled, water in the pump assembly 100 cannot flow out, and waste of water resources is avoided. Also, the trouble of cleaning the outflow water can be avoided.
