When the pump and the filter element are repaired and replaced, the pump assembly 100 and the filter element assembly 300 are detached from the pump base assembly 200 and the filter element base assembly 400 respectively, and then the pump assembly 100 and the filter element assembly 300 are replaced with new ones.
Therefore, the utility model provides a quick installation and the dismantlement of pump subassembly 100 and filter element group spare 300 can be realized to the modularization purifier, greatly reduced installation and time and process of dismantling to reduce the cost of production and maintenance.
Preferably, as shown in fig. 3-4, the pump assembly 100 may have a pump mounting head. The pump mounting head of the pump assembly 100 refers to a portion of the pump assembly 100 connected to the pump mount assembly 200, and in the drawing, a lower end of the pump assembly 100, and the pump mounting head may be provided with a pump inlet joint (not shown due to an angle problem) and a pump outlet joint (not shown due to an angle problem). The pump mounting head may be configured to be connected to the pump base assembly 200, and when the pump assembly 100 is mounted to the pump base assembly 200 by the pump mounting head, the pump inlet connector and the pump outlet connector may be connected to a waterway within the pump base assembly 200, thereby further enabling quick assembly and disassembly of the pump assembly 100 and the pump base assembly 200.
The pump mount assembly 200 may be provided with a pump mount socket 210. The pump mounting head of the pump assembly 100 is removably mounted within the pump mount socket 210. The bottom of the pump mount socket 210 may be provided with a pump mount water inlet connector 221 and a pump mount water outlet connector 222. Pump mount water inlet fitting 221 is connected to a pump water inlet fitting of pump assembly 100. Pump base outlet fitting 222 is connected to a pump outlet fitting of pump assembly 100.
By connecting the pump mount socket 210 to the pump mounting 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 pump mount assembly 200. And, fixing through the pump mount slot 210 has the advantages of simple structure, low processing cost, and the like.
The outer wall of the pump mount assembly 200 may be provided with a pump mount connection water inlet 231 and a pump mount connection water outlet 232. Pump mount connection inlet 231 communicates within pump mount assembly 200 to pump mount inlet connector 221. Pump mount connection outlet 232 communicates with pump mount outlet fitting 222 within pump mount assembly 200. The pump base connecting water inlet 231 and the pump base connecting water outlet 232 are both connected to the waterway connecting assembly.
Like this, the business turn over water of pump seat subassembly 200 all is via filter core seat subassembly 400, can make the business turn over water outlet of purifier all set up in the one side at filter core seat subassembly 400 place for the business turn over water outlet overall arrangement of purifier is neater. Especially, when the water purifier is a shell water purifier or other components are arranged outside the pump base assembly 200 and the filter element base assembly 400, the water inlet and the water outlet of the water purifier are arranged on one side of the filter element base assembly 400, so that the shell of the water purifier or the other components can be arranged conveniently.
Preferably, as shown in fig. 1-4, the pump assembly 100 can include a housing 120 and a pump 130. A pump mounting head may be located on the housing 120. The housing 120 is fixed to the pump base assembly 200 by a mounting head. The pump 130 is enclosed within the housing 120. The housing 120 may take the shape of a bottle as shown, and in other embodiments not shown, the housing 120 may have other shapes as long as it can accommodate the pump 130.
Because the water path layout and the water making capability of different water purifiers are different, the type and the model of the adopted pump 130 are different, so that the appearance and the structure of the pump 130 are different. If a suitable pump block assembly 200 is designed for each type of pump 130, the manufacturing cost is increased because of the complicated structure of the pump block assembly 200 due to various interfaces and internal flow passages. While various types of pumps 130 can be packaged by properly designing the structure of the housing 120, the fixing manner between the pump 130 and the housing 120 can be more flexible, for example, by an accessory component (such as an elastic sleeve, etc.), so as to provide the possibility of standardizing the housing 120 and the pump holder assembly 200, that is, one or more types of pump holder assemblies 200 can be adapted to various types of pumps 130. Therefore, the structure can greatly reduce the number of moulds, the inventory occupation and the production cost.
Alternatively, the pump inlet and outlet of the pump 130 itself may be in direct communication with the pump mount assembly 200. The housing 120 may be provided with through holes through which the pump inlet and outlet ports of the pump 130 itself are connected to the pump mount inlet and outlet fittings 221 and 222 on the pump mount assembly 200. In this case, the pump inlet and the pump outlet after passing through the through hole form the aforementioned pump inlet and outlet connections.
For example, the aforementioned pump inlet and outlet connections may be provided on the housing 120, the pump inlet of the pump 130 itself may be communicated with the pump inlet connection, and the pump outlet of the pump 130 itself may be communicated with the pump outlet connection. Alternatively, the pump inlet of the pump 130 itself and the pump inlet connection on the housing 120 may be communicated through a quick-connect. The quick connector is a connector which can realize the connection or disconnection of pipelines without tools. By providing a quick-connect, disassembly of the pump 130 from the housing 120 may be facilitated. Alternatively, the pump inlet of the pump 130 itself may be connected to the pump inlet connector of the housing 120 by welding, bonding, or any other means. The pump outlet of the pump 130 itself may be in communication with a pump outlet connection on the housing 120 in any of the manners described above. Wherein the pump inlet and outlet of the pump 130 itself may be connected to the pump inlet and outlet of the housing 120 in the same or different manners.
Since the interface locations and sizes of different models of pumps 130 may vary, the housing 120 and the pump block assembly 200 can be completely standardized by switching the housing 120 between the pumps 130 and the pump block assembly 200. If desired, the fixation between the different pumps 130 and the housing 120 inside the housing 120 may be by additional means, such as an elastic sleeve or the like, and the water connection may be by additional means, such as a hose or the like. Thus, the same type of housing 120 and pump base assembly 200 can be used for different water purifiers, thereby realizing the standardization of the water purifiers and being very convenient in future design and production.
As shown in fig. 8, the cartridge assembly 300 can include a filter flask 320 and a filter cartridge 330 housed within the filter flask 320. The housing 120 may employ a filter bottle 320. Alternatively, the housing 120 may be any suitable filter flask, such as a front filter element assembly filter flask, a rear filter element assembly filter flask, etc., in which the water inlet and outlet of the filter flask may serve as the water inlet and outlet of the housing 120; the filter cartridge 320 may also comprise a reverse osmosis cartridge assembly filter cartridge or other filter cartridge having more than two water ports, two of which may serve as water inlets to the housing 120 and the remaining water ports may be used to place the first electrical connector 110 or empty. Correspondingly, the pump block assembly 200 may also employ a cartridge block assembly 400.
Since the filter flask 320 and the housing 120 have the same structure, they can be manufactured using the same set of molds. Therefore, the number of moulds required for producing the filter flask 320 and the shell 120, the types of relevant parts such as relevant water way joints, water pipes and the like can be reduced, and the inventory occupation and the production cost are reduced; the pump and the filter element can adopt the same design and production scheme, and the design and production difficulty is reduced, so that the standardization of the booster pump and the filter element is realized. The filter bottle 320 can be various existing filter bottles, when the filter bottle is adopted as the shell 120, the shell 120 does not need to be designed, and related parts such as a special mold, related water path connectors, water pipes and the like do not need to be designed and produced for the shell 120, so that the cost can be further reduced, and the cost is greatly reduced; meanwhile, the process for manufacturing the filter bottle 320 is mature, the supply channel is wider, the market holding capacity is larger, the universality and the replaceability are stronger, and more importantly, the waste and overdue filter bottle 320 can be selected as the shell 120, so that the cost is further reduced, the waste is recycled, and the energy is saved and the environment is protected.
Preferably, the first electrical connector 110 may also be disposed on the housing 120. The power cord of the pump 130 is electrically connected to the first electrical connector 110. By powering the first electrical connector 110, the motor within the pump 130 can be activated, thereby activating the pump. The power cord of the pump 130 and the first electrical connector 110 may be electrically connected by any means such as a quick connector. The first electrical connector 110 may be a plug or a receptacle. The first electrical connector 110 allows for quick connection of the pump assembly 100 to an external power source and facilitates standardization of the housing 120.
Further, as shown in fig. 4, the first electrical connector 110 may be disposed on the pump mounting head. The bottom of the pump mount socket 210 may also be provided with a second electrical connector 240. The second electrical connector 240 may be removably electrically connected with the first electrical connector 110. The second electrical connector 240 and the first electrical connector 110 may employ a plug and socket, electrical contacts, etc. that are well known in the art and therefore will not be described in further detail herein. By properly arranging the structure of the pump base assembly 200, when the pump assembly 100 is mounted to the pump base assembly 200, the first electrical connector 110 can be connected with a power supply through the pump base assembly 200; conversely, when the pump assembly 100 is disassembled, removal of the pump assembly 100 can disconnect the first electrical connector 110 from the power source. Thereby, the time and procedures for mounting and dismounting the pump assembly 100 are further reduced, thereby reducing the cost of mounting and dismounting.
Preferably, as shown in fig. 8, the pump assembly 100 may further include one or more of an elastic sleeve 140, a first damper elastic member 151, and a second damper elastic member 152. The elastic sleeve 140 may be fitted over the outer sidewall of the pump 130. The elastic sleeve 140 may be clamped between an outer sidewall of the pump 130 and an inner sidewall of the housing 120. The first shock-absorbing elastic member 151 may be sandwiched between the pump 130 and the pump mounting head in the axial direction of the housing 120. The second shock-absorbing elastic member 152 may be clamped between the pump 130 and an inner wall of the rear portion of the housing 120 in the axial direction of the housing 120. The tail and the pump mounting head may be provided at both end portions of the housing 120 in the axial direction, respectively.
The elastomeric sleeve 140 may also secure the pump 130 within the housing 120. By changing the overall dimensions of the elastic sleeve 140, different types of pumps 130 can use the same type of housing 120, thereby reducing the number of dies and the processing cost.
The first and second shock-absorbing elastic members 151 and 152 may have the same or different structures. Preferably, the first and second shock-absorbing elastic members 151 and 152 may be springs. As is known in the art, the pump 130 vibrates when operating, and generates a loud noise when the pump 130 impacts the housing 120. The first and second shock-absorbing elastic members 151 and 152 may form an elastic buffer between the pump 130 and the housing 120, to reduce impact due to vibration, thereby reducing noise of the pump 130. Also, the first and second shock-absorbing elastic members 151 and 152 may also fix the pump 130 within the housing 120. Meanwhile, by changing the outer dimensions of the first and second shock-absorbing elastic members 151 and 152, the same type of housing 120 can be used for different types of pumps 130.
Preferably, the pump block assembly 200 is removably connected to the cartridge block assembly 400. The manner in which the pump block assembly 200 is removably coupled to the cartridge block assembly 400 may be arbitrary, such as by a threaded connection, snap fit, etc. Based on this, water route coupling assembling includes first water receiving mouth and second water receiving mouth. The first water receiving port may be disposed on the pump base assembly 200. The second water receiving port may be provided on the cartridge holder assembly 400. The first water receiving port and the second water receiving port are respectively provided with a rotary clamping joint and a rotary clamping seat. The first water receiving port is communicated with the second water receiving port by connecting the rotary clamping joint into the rotary clamping seat in a rotary clamping manner.
By connecting the pump base assembly 200 to the filter element base assembly 400, only one of the pump base assembly 200 or the filter element base assembly 400 needs to be fixed, and the other of the pump base assembly 200 or the filter element base assembly 400 can be fixed therewith, so that the fixing cost of the modular water purifier is low; when one of the pump block assembly 200 and the filter element seat assembly 400 needs to be replaced and maintained, the pump block assembly 200 and the filter element seat assembly 400 can be detached, only the parts needed by maintenance are replaced, and the replacement and maintenance cost is reduced.
Preferably, the pump block assembly 200 may be hinged to the cartridge block assembly 400 by a hinge 250. Hinge 250 may take the form of any type of hinge, whether existing or that may be present in the future, that is capable of performing the functions described above. By providing the hinge 250, the modular water purifier can be fixed by fixing only one of the pump base assembly 200 or the filter element base assembly 400. Meanwhile, for the occasion with limited installation space, the pump base assembly 200 and the cartridge base assembly 400 can be rotated relatively by the hinge 250 to adapt to the occasion.
Further, as shown in fig. 1-4, hinge 250 may include a first hinge axis 251, a second hinge axis 252, and a pin axis 253. The first hinge shaft 251 may be connected to a lower portion of a side of the pump holder assembly 200. The first hinge shaft 251 may have a first shaft hole. The second hinge shaft 252 may be connected to a lower portion of a side surface of the cartridge holder assembly 400. The second hinge shaft 252 may have a second shaft hole. The pin 253 may pass through the first shaft hole and the second shaft hole. The first hinge axis 251 is pivotable with respect to the second hinge axis 252. The hinge 250, which is connected to the pump block assembly 200 and the lower side of the cartridge block assembly 400, reduces interference with each other when the two are pivoted relative to each other, making it possible to pivot the two between 0 and 180 degrees. Moreover, the hinge 250 has the advantages of simple structure, flexible pivoting and the like.
Further, as shown in fig. 1-4, the axis of the first shaft bore may be perpendicular to the axial direction of the pump assembly 100. The axis of the second shaft bore may be perpendicular to the axial direction of the filter element assembly 300. Thus, the pump assembly 100 and the filter element assembly 300 can respectively pivot in a plane perpendicular to the axes of the first shaft hole and the second shaft hole by taking the axes of the first shaft hole and the second shaft hole as centers, and the pivoted water purifier is regular in structure and further can adapt to more installation occasions.
Preferably, as shown in connection with fig. 1 to 4, the waterway connection assembly may include a first waterway connection pipe 510 and a second waterway connection pipe 520. The first and second waterway connection pipes 510 and 520 may be respectively located at both sides of the hinge 250. First and second waterway connection pipes 510 and 520 are communicated between the pump block assembly 200 and the cartridge block assembly 400. Specifically, the pump mount assembly 200 may be provided with a pump mount connection water inlet 231 and a pump mount connection water outlet 232. The pump mount connection inlet 231 and the pump mount connection outlet 232 may be respectively located at both sides of the hinge 250. A cartridge seat connection inlet 432 and a cartridge seat connection outlet 431 may be provided on cartridge seat assembly 400. The cartridge seat connection inlet 432 and the cartridge seat connection outlet 431 may be respectively located at both sides of the hinge 250. The pump base connection inlet 231 and the cartridge base connection outlet 431 may be located at one side of the hinge 250. The pump base connection outlet 232 and cartridge base connection inlet 432 may be located on the other side of the hinge 250. The first waterway connection pipe 510 may communicate the pump seat connection inlet 231 and the cartridge seat connection outlet 431. The second waterway connection pipe 520 may communicate the pump seat connection outlet 232 and the cartridge seat connection inlet 432. First waterway connection pipe 510 and second waterway connection pipe 520 may be flexible pipes, and may be prevented from being restricted by the waterway connection assembly when pump base assembly 200 is moved with respect to cartridge base assembly 400. The first and second waterway connection pipes 510 and 520 may be used for an inlet pipe and an outlet pipe of the pump 130, respectively. With first waterway connection pipe 510 and second waterway connection pipe 520 respectively disposed at both sides of hinge 250, it is more advantageous to dispose pump base assembly 200 and cartridge base assembly 400 in a pivotable connection, and thus, waterway connection assembly's structure is simple and installation is convenient.
Preferably, as shown in fig. 4-5, the pump assembly 100 may have a pump mounting head. The pump mount assembly 200 may have a pump mount socket 210. The pump mount socket 210 may receive at least a portion of a pump mounting head. The pump mounting head may be provided with a pump locking portion on a side wall thereof. The pump mount assembly 200 may be provided with a pump lock engagement portion located on an outer side surface of the pump mount socket 210. The pump locking portion and the pump locking mating portion may cooperate to lock the pump assembly 100 to the pump mount assembly 200. The pump locking portion and the pump locking fitting portion may have various structures as long as both locking and unlocking are possible. Several preferred modes thereof will be described in detail later. Through setting up pump locking portion and pump locking cooperation portion, can make pump assembly 100 lock to pump base subassembly 200, ensure that pump assembly 100 can not break away from pump base subassembly 200 in the use, improve the stability of modularization purifier.
In a preferred embodiment, as shown in fig. 4, the pump locking part 160 may be a pump locking projection provided on an outer sidewall of the pump mounting head. The pump locking projections may be provided at any suitable location on the outer side wall of the mounting head. The number of pump locking tabs on the outer sidewall of the pump mounting head may be arbitrary. Preferably, the number of the pump locking projections is plural and is uniformly distributed along the circumferential direction of the outer sidewall of the pump mounting head.
The pump mount assembly may include a pump mount body 281 and a pump rotating member 282. The pump mount socket 210 may be provided on the pump mount body 281. The pump rotating member 282 may be rotatably disposed on the pump holder body 281 around the pump holder insertion groove 210 between a pump locking position and a pump unlocking position. The pump rotating member 282 is rotatable by manual force between a pump locking position and a pump unlocking position. Alternatively, the pump rotating member 282 may be rotated by a motor or the like between the pump locking position and the pump unlocking position. The pump lock fitting portion 270 may be a pump lock fitting projection provided on an inner sidewall of the pump rotating member 282. The pump lock mating portion 270 is disposed spaced apart from the bottom of the pump mount socket 210. The spaced apart spaces may be used to accommodate the pump locking portion 160. When the pump rotating member 282 is in the pump unlocking position, the pump lock fitting portion 270 may be misaligned with the pump lock portion 160 in the circumferential direction of the pump holder insertion groove 210. In this way, the pump assembly 100 can be inserted into or pulled out of the pump holder body 281 in the axial direction thereof. When the pump rotating member 282 is in the pump locking position, the pump lock fitting 270 may be aligned with the pump locking portion 160 in the circumferential direction of the pump holder insertion groove 210, and the pump locking portion 160 may be caught in the spaced space. At this time, the pump locking mating part 270 may be completely aligned with the pump locking part 160, and the pump locking mating part 270 may also be partially aligned with the pump locking part 160 as long as the pump locking part 160 can be caught in the spaced space. In this way, the pump assembly 100 is prevented from being pulled out, thereby achieving locking of the pump assembly 100 to the pump holder body 281.
With this arrangement, the pump assembly 100 can be directly inserted into the pump seat 281, and the pump assembly 100 can be locked and unlocked by rotating the pump rotating member 282, so that the pump assembly 100 is prevented from being separated from the pump seat 281 during use, and the stability of the modular water purifier is improved. Furthermore, due to the direct-insertion installation, water cannot flow in the waterway between the pump assembly 100 and the pump base assembly 200.
Preferably, as shown in fig. 3-4, the pump base assembly 200 may further include a pump lock sleeve 290. The pump lock sleeve 290 may be rotatably mounted on the pump mount body 281 around the pump mount slot 210. The pump sleeve 290 may be connected to the pump rotating member 282. The manner in which the pump locking sleeve 290 is connected to the pump rotating member 282 may be arbitrary. In the embodiment shown in the figures, the inner side wall of the pump sleeve 290 may be provided with a projection 291. The outer side wall of the pump rotating member 282 may be provided with a groove 292. The connection of the pump lock sleeve 290 to the pump rotating member 282 is achieved by snapping the projection 291 into the groove 292. In other embodiments not shown, the pump lock sleeve 290 may be connected to the pump rotating member 282 by welding, adhesive, or the like.
By providing the pump locking sleeve 290, it is possible to effectively prevent impurities such as dust from falling into the pump rotating member 282, which may cause the occurrence of the conditions such as the occurrence of the rotation jamming and the occurrence of the unstable rotation speed. Further, the user can be prevented from touching the pump rotating member 282, and the occurrence of a dangerous accident when the pump rotating member 282 rotates can be avoided. In addition, the pump lock sleeve 290 can also surround the pump holder body 281 and the pump rotating member 282, so that the pump holder assembly 200 is more neat in appearance.
Preferably, as shown in fig. 3-4, pump mount assembly 200 may further include a pump return 283. The pump return 283 may be connected between the pump housing 281 and the pump rotating member 282. The pump return 283 may be used to return the pump rotating member 282 from the pump unlocked position to the pump locked position. Preferably, the pump return 283 may be a spring.
As described above, during installation of the pump assembly 100, the pump rotating member 282 is moved to the pump unlocked position, where the pump reset 283 may be in a compressed or extended large amount. When the pump assembly 100 is installed in place, i.e., the pump latch 160 moves past the pump latch mating portion 270 and between the pump latch mating portion 270 and the bottom of the pump holder slot 210, the pump return 283 may release its stored elastic potential energy to return the pump rotating member 282 to the pump locking position. At this time, the pump return 283 may be in a naturally extended state, or compressed or stretched by a small amount.
By providing the pump reset member 283, the pump rotating member 282 can be automatically rotated to the pump locking position when the pump assembly 100 is installed in place, thereby reducing the number of operation steps and providing better man-machine interaction.
Further, as shown in fig. 4, the pump locking portion 160 and the pump locking mating portion 270 may each be a wedge-shaped protrusion. When the pump set 100 has not been inserted into the pump mount socket 210 on the pump mount assembly 200, the pump rotary member 282 is in the pump locking position, and as the pump set 100 is progressively inserted into the pump mount socket 210 in the axial direction, the pump locking portion 160 may press the pump locking mating portion 270, thereby driving the pump rotary member 282 to rotate from the pump locking position to the pump unlocking position. When the pump rotating member 282 is in the pump unlocked position, the pump lock 160 on the pump assembly 100 can move past the pump lock mating portion 270 into the space where the pump lock mating portion 270 is spaced from the bottom of the pump holder slot 210. At this time, the pump rotating member 282 may be manually rotated or returned to the pump locking position by means of the pump returning member 283, whereby the pump assembly 100 may be locked to the pump seat 281.
With this arrangement, when the pump assembly 100 is inserted into the pump mount slot 210, the pump rotation member 282 can rotate therewith, so as to reduce the number of operation steps and improve the man-machine interaction effect on the basis of locking the pump assembly 100 to the pump mount body 281.
In a second preferred embodiment, as shown in fig. 5, the pump locking part 160' may include a screw groove on an outer sidewall of the mounting head of the pump assembly 100. The spin chuck groove may extend in a circumferential direction of the pump mounting head. One end of the rotary clamping groove is closed and the other end is open. The spin slot may be formed by an L-shaped protrusion 293 provided on the pump mounting head. The pump locking mating portion 270' may be a snap-on projection provided on an inner sidewall of the pump mount slot 210. The rotary clamping bulge can be clamped into the rotary clamping groove. Illustratively, two rotation locking protrusions may be disposed on the inner sidewall of the pump holder slot 210.
When the pump assembly 100 is installed, the L-shaped protrusion 293 on the pump assembly 100 can be aligned with the gap between the two rotation-locking protrusions, and after the pump assembly 100 is inserted into place along the axial direction, the pump assembly 100 can be rotated to allow the rotation-locking protrusions to enter the rotation-locking grooves from the openings of the rotation-locking grooves, and the rotation-locking protrusions are locked to the rotation-locking grooves, so that the pump assembly 100 can be locked to the pump base assembly 200. When pump assembly 100 is disassembled, rotating pump assembly 100 can disengage the bayonet projections from the bayonet slots, thereby allowing pump assembly 100 to be unlocked from pump mount assembly 200. The pump assembly 100 can then be pulled out in the axial direction.
Through setting up the protruding and card slot of revolving clip, can lock pump assembly 100 to pump base subassembly 200 convenient and fast ground, can ensure that pump assembly 100 can not break away from pump base 281 in the use, improves the stability of modularization purifier. And the rotary clamping protrusion and the rotary clamping groove are simple in structure and easy to realize.
In a third preferred embodiment, shown in FIG. 6, both the pump inlet and outlet connections are rigid water tubes that extend in the axial direction of the housing 120. The rigid water tube may extend from the mounting head in a direction away from the housing 120. Correspondingly, the pump mount inlet 221 and outlet 222 may also be rigid water pipes. The pump block assembly 200 may also include a first quick connector 295 and a second quick connector 296. In a state where the pump assembly 100 is mounted to the pump mount assembly 200, the first quick connector 295 may be sleeved on the pump inlet connector and the pump mount inlet connector 221, and the pump inlet connector and the pump mount inlet connector 221 may be connected. The second quick connector 296 can be sleeved on the pump-out water connector and the pump base water connector 222, and the pump-out water connector and the pump base water connector 222 can be connected.
Through the arrangement, the pump assembly 100 can be locked to the pump base assembly 200, the pump assembly 100 is ensured not to be separated from the pump base assembly 200 in the using process, and the stability of the modular water purifier is improved. 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. 7, the pump locking part 160 "of the pump assembly 100 may include external threads provided on the mounting head thereof, and the pump locking fitting part 270" of the pump holder assembly 200 may further include external threads provided on the outer circumferential surface thereof. Pump assembly 100 and pump base assembly 200 may be connected by a threaded sleeve 294, and threaded sleeve 900 may be internally threaded. The pump assembly 100 and the pump holder assembly 200 are locked by screwing the pump assembly 100 and the pump holder assembly 200 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, the cartridge assembly 300 can have a cartridge mounting head. The mounting head of the cartridge assembly 300 refers to the portion of the cartridge assembly 300 that is attached to the cartridge holder assembly 400, shown as the lower end of the cartridge assembly 300.
