Description

Technical Field

[0001] This invention relates to the field of fluid transport, particularly to the field of household appliance technology, and especially to a pump device. Background Technology

[0002] Some household appliances, such as dishwashers, use pumps as power devices to deliver water to the washing chamber to circulate and clean dishes and utensils. During the washing process, food residue can easily enter the pump chamber, causing hygiene and health problems. One type of pump in related technology uses an ultraviolet lamp to irradiate the pump chamber. The ultraviolet lamp is located inside the pump chamber, which poses a safety hazard and increases the difficulty of sealing the pump chamber. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the problems in the prior art by providing a pump.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pump device includes a pump body and a drive unit, the drive unit being mounted on the pump body. The pump body has a receiving cavity. The pump device has a disinfection / sterilization lamp located outside the receiving cavity and facing the receiving cavity. The pump body has a light-transmitting part, through which the light from the disinfection / sterilization lamp can pass.

[0006] The pump device of the above technical solution, since the disinfection / germinating lamp is located outside the receiving cavity, the light-transmitting part of the pump body isolates the disinfection / germinating lamp from the receiving cavity, which can effectively reduce the safety problem of leakage of the disinfection / germinating lamp, and also effectively reduce the installation problem of the disinfection / germinating lamp and the sealing problem of the receiving cavity.

[0025] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Other technical solutions obtained by those skilled in the art without creative effort are all within the protection scope of the present invention. In addition, it should be understood that the following terms such as "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," which indicate orientation or positional relationship, are based only on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0026] like Figures 1-15 As shown, a pump device according to one embodiment includes a pump body 2 and a drive unit 1. The drive unit 1 is mounted on the pump body 2. The pump body 2 has a receiving cavity 200. The pump includes a blade 4 and a pump shaft 6. The blade 4 is fixed to the pump shaft 6. The pump device includes an inner cover 5. The inner cover 5 is integrally or sealedly connected to the inlet portion 3 of the pump device. The inner cover 5 has a crushing flow channel 500. The inlet portion 3 has an inlet flow channel 300. The crushing flow channel 500 communicates with the inlet flow channel 300. The inner diameter of the crushing flow channel 500 is smaller than the inner diameter of the receiving cavity 200. The blade 4 is located in the crushing flow channel 500.

[0027] In one embodiment, the pump device is used in a dishwasher as a power source to deliver cleaning water to the dishwasher's cleaning chamber for cyclic cleaning of dishes, utensils, etc. During the cyclic cleaning process, food and other impurities can easily enter the pump, causing blockages and other problems for the dishwasher. In this embodiment, the blade 4 is located in the crushing channel 500 of the inner cover 5. Fluid flows into the crushing channel 500 from the inlet channel 300. Because the inner diameter of the crushing channel 500 is smaller than the inner diameter of the receiving cavity 200, impurities entering the crushing channel 500 are less likely to bypass the blade 4, increasing the actual stirring capacity of the blade 4. The impurities carried by the fluid are more easily crushed in the crushing channel 500, thereby improving the pump device's ability to crush impurities.

[0028] In one embodiment, such as Figure 3 As shown, the inlet 3 of the pump device includes an inlet pipe. One end of the inlet pipe, which is connected to the pump body 2, is sealed and fitted onto the upper part of the inner cover 5. The lower part of the inner cover 5 extends into the receiving cavity 200. The crushing channel 500 of the inner cover 5 has a certain length, so that the fluid flows a certain distance along the length of the channel within the crushing channel 500. The blade 4 is located within the crushing channel 500, and the blade 4 is kept at a certain distance from the outlet of the crushing channel 500 to prevent impurities from shifting away from the blade 4 due to pressure release at the outlet of the crushing channel 500, thereby reducing the crushing effect of the blade 4.

[0029] In one embodiment, the inlet 3 is installed at the inlet of the pump device. The inlet 3 is made of a flexible rubber tube, which ensures the connection is sealed and is also very suitable for pump devices with a certain degree of vibration. The inner cover 5 is made of relatively rigid plastic or silicone material. The rubber tube is sleeved on the upper part of the inner cover 5. The inner cover 5 and the side wall of the inlet of the pump device clamp and hold the rubber tube, thereby simultaneously achieving the sealing and fixing of the rubber tube.

[0030] In another embodiment, such as Figure 4 As shown, the inner cover 5 and the inlet 3 are an integral part, that is, they also serve as the inlet pipe. In this case, the inlet pipe can appropriately extend into the flow inlet of the pump device, and this extended part can be considered as at least a portion of the inner cover 5. At this time, the inner cover 5 and the inlet 3, which are integral parts, are made of relatively rigid plastic or silicone material and are sealed to the pump body 2 by a sealing ring.

[0031] In one embodiment, at least a portion of the inner cover 5 is located in the receiving cavity 200, and the blade 4 is located in the portion of the inner cover 5 within the receiving cavity 200. The crushing channel of the inner cover 5 serves as a guide channel when the fluid enters the receiving cavity 200, maintaining the fluid flow along the axial direction of the pump shaft 6 within a certain range, so that the fluid flows perpendicular to the horizontal direction of the stirring plane of the blade 4, thereby increasing the crushing effect of the blade 4.

[0032] In another embodiment, the inner cover 5 is located outside the receiving cavity 200. For example, if the inner cover 5 is fitted onto the inlet 3 but does not extend into the receiving cavity 200, the blade 4 is also located outside the receiving cavity 200.

[0033] In one embodiment, the distance between the blade 4 and the inner wall of the inner cover 5 is no more than 1 cm, which reduces the amount of residue in the fluid that enters the receiving cavity 200 without being crushed by the blade 4, and also reduces the probability of larger pieces of residue, such as residue with an outer diameter greater than 1 cm, entering the receiving cavity 200.

[0034] In one embodiment, the pump device includes an impeller 7, which is fixed to a pump shaft 6. The pump device also includes a baffle ring 8, which is fixed to the impeller 7. At least a portion of the baffle ring 8 is located in the space between the impeller 7 and the inner cover 5. The opening corresponding to the inner ring of the baffle ring 8 is opposite to and communicates with the crushing channel 500. A first vortex channel 700 is provided between the baffle ring 8 and the impeller 7, and the first vortex channel 700 communicates with the crushing channel 500.

[0035] Pump shaft 6 drives impeller 7 to rotate, impeller 7 drives fluid vortex and swirls the fluid, thereby realizing the fluid conveying function of the pump device. Most of the fluid flows through inlet 3 into crushing channel 500, then through crushing channel 500 into first vortex channel 700, flows out of first vortex channel 700 and then out of pump device. Compared with the prior art, the pump device of this application has crushing channel 500, which can make the residue flow through crushing channel 500 more concentratedly, and increase the effect of blade 4 in crushing impurities.

[0036] The opening corresponding to the inner ring of the barrier ring 8 serves as the transition port between the crushing channel 500 and the first vortex channel 700, allowing the fluid to enter the first vortex channel 700 from the crushing channel 500 as much as possible. This ensures that most of the fluid flows stably from the crushing channel through the first vortex channel 700, reducing the amount of fluid that flows out of the crushing channel 500 and into the surrounding receiving cavity 200. This improves the fluid delivery effect of the pump device and increases the path of the fluid along the length of the crushing channel 500, preventing the fluid from flowing to the periphery too early and reducing the crushing effect of the blade 4.

[0037] Furthermore, such as Figure 3 , Figure 6 , Figure 7 As shown, the barrier ring 8 includes a base 801 and a flange 802, at least a portion of which is located around the outer periphery of the inner cover 5. The distance between the flange 802 and the outer wall of the inner cover 5 is minimized to further ensure that most of the fluid flows relatively stably from the crushed flow through the first vortex channel 700.

[0038] In one embodiment, such as Figure 8As shown, the impeller 7 includes a mounting shaft 702, a disc 71, and blades 701. The mounting shaft 702, disc 71, and blades 701 are integrated or fixed. The mounting shaft 702 is fixed to the pump shaft 6, the blades 4 are fixed to the mounting shaft 702, the blades 701 are spirally distributed on the disc 71, and the barrier ring 8 is fixed to the blades 701.

[0039] In one embodiment, the mounting shaft 702 has a mounting channel with an internal thread, and the pump shaft 6 has a corresponding external thread. The mounting shaft 702 is threadedly connected and fixed to the pump shaft 6.

[0040] In one embodiment, the impeller 7 is made of plastic, and the blade 4 can be fixed to the upper end of the mounting shaft 702 by laser welding. Using laser welding to fix the blade 4 to the mounting shaft 702 is more convenient than the installation method of fixing parts in the prior art, which can save materials and greatly reduce costs in mass production.

[0041] In another embodiment, the impeller 7 includes blades 701 and a mounting shaft 702. The blades 701 are integrally formed with or fixed to the sidewall of the mounting shaft 702. The blades 701 are spirally distributed along the axial sidewall of the mounting shaft 702, and the barrier ring 8 is fixed to the blades 701. In this embodiment, the blades 701 can be integrally formed with the mounting shaft 702.

[0042] In one embodiment, such as Figure 5 As shown, the pump body 2 includes an inner ring wall 220, and a second vortex flow channel 210 is provided between the inner ring wall 220 and the side wall portion 202 of the pump body 2. The second vortex flow channel 210 is connected to the first vortex flow channel 700. The pump includes an outlet portion 230 located in the side wall portion 202 of the pump body 2. The inner diameter of the second vortex flow channel 210 gradually increases along the direction facing the outlet portion 230.

[0043] Under the centrifugal force generated by the rotation of impeller 7, the fluid flows from the first vortex channel 700 to the second vortex channel 210, and then flows out of the pump device.

[0044] In one embodiment, the drive unit 1 includes a motor component mounted to the pump body 2, and the pump device also includes a water distribution plate 9. The stator coil 10 assembly of the motor component is sealed and isolated from the receiving cavity 200 of the pump device through the water distribution plate 9, so that the fluid does not come into contact with the coil assembly. At least a portion of the rotor 11 of the motor component is located in the inner cavity of the water distribution plate 9, and the pump shaft 6 is connected to the rotor 11.

[0045] In one embodiment, such as Figure 3 , Figure 8As shown, the disc 71 has a through-hole 703, which is located on the side of the first vortex channel 700 near the mounting shaft 702. A small amount of fluid flows along the gap between the inner ring wall 220 and the impeller 7 to the water distribution plate 9, which can cool the high-speed rotating rotor 11 and pump shaft 6. The through-hole 703 can realize the circulation of this part of the cooling fluid to a certain extent. As the impeller 7 drives the fluid to rotate, a negative pressure is generated at the center of the disc 71. The fluid between the impeller 7 and the water distribution plate 9 is blocked by the disc 71 and is hardly subjected to centrifugal force, but is attracted by the negative pressure at the center of the disc 71. Thus, a small amount of fluid flows along the gap between the inner ring wall 220 and the impeller 7 to the water distribution plate 9, and then enters the first vortex channel 700 through the through-hole 703, realizing the cooling circulation of the fluid. The pump device can be placed vertically or horizontally along its pump shaft 6. When placed horizontally, the fluid has to overcome less gravity as it enters the first vortex channel 700 from the flow hole 703, making it easier to achieve circulating cooling.

[0046] In one embodiment, the barrier ring 8 is welded and fixed to the blade 701 of the impeller 7. The barrier ring 8 has at least two sets of through holes 803, which correspond to the blade 701 of the impeller 7. The side of the through hole 803 facing away from the blade 701 has a groove 8031.

[0047] Furthermore, the barrier ring 8 and the blades 701 of the impeller 7 are laser-welded. The position corresponding to the through hole 803 is the laser welding point. During the laser welding process, the impeller 7 at the welding point melts and enters the through hole 803. After cooling, the barrier ring 8 and the blades 701 are fixed. Figure 5 , Figure 6 As shown, after laser welding, the impeller 7 and the barrier ring 8 form a first weld point 7011 at the through hole 803, thus fixing the impeller 7 and the barrier ring 8. The groove 8031 ​​allows the molten impeller 7 at the weld point to fill the inverted T-shaped space, further increasing the reliability of fixing the barrier ring 8 to the blades 701 of the impeller 7.

[0048] In one embodiment, the through-holes 803 correspond one-to-one with the blades 701. Each set of through-holes 803 includes at least two through-holes 8030, and the through-holes 8030 are distributed along the helical direction of their corresponding blades 701. During laser welding, the impeller 7 at the weld point melts and enters the through-holes 8030, where it cools to fix the barrier ring 8 and the blades 701. The through-holes 803 include at least two through-holes 8030, making the laser-welded impeller 7 and barrier ring 8 structure more stable.

[0049] In another embodiment, any set of through holes 803 includes a filling port 8030 that extends along the helical direction of the blade 701, i.e., the filling port 8030 forms a shape similar to the helix of the blade 701.

[0050] In one embodiment, the blade 4 is welded and fixed to the mounting shaft 702. The mounting shaft 702 has a mounting groove 7020 corresponding to the blade 4. The blade 4 has a through material hole 400. A portion of the blade 4 is located in the mounting groove 7020 and the material hole 400 is opposite to the bottom of the mounting groove 7020.

[0051] Furthermore, the blade 4 includes a central portion 41 and blade portions 42 located on both sides of the central portion 41. At least a portion of the central portion 41 is located in the mounting groove 7020. A feed hole 400 is formed in the central portion 41. The blade 4 is laser-welded to the mounting shaft 702. The location of the feed hole 400 serves as the welding point. The feed hole 400 is positioned as close as possible to the center of the blade 4, so that the blade portions 42 on both sides of the blade 4 are subjected to relatively balanced forces after laser welding. Figure 5 , Figure 6 As shown, after the blade 4 is laser welded to the mounting shaft 702, a second weld point 7021 is formed at the through hole portion 803, thereby fixing the blade 4 to the mounting shaft 702. The blade 4 portion can consist of two, three, four, or more blades, which are evenly distributed around the outer periphery of the middle portion 41.

[0052] In one embodiment, such as Figure 9 As shown, the blade section 42 includes a horizontal blade 421 and a bent blade 422. The bent blade 422 is integral with the horizontal blade 421, and the bent blade 422 bends from the horizontal blade 421 toward the inlet 3 of the pump device. The horizontal blade 421, in conjunction with the bent blade 422, increases the working space of the blade section 42, thereby increasing the crushing capacity of the blade 4. Furthermore, the bending height is no more than 0.5 cm to avoid the formation of vortices at this point, which would cause residue to move toward the inner wall of the inner casing 5 and affect the actual crushing effect of the blade 4. Of course, in another embodiment, the blade section 42 may not use the bent blade 422 described above.

[0053] In one embodiment, such as Figures 10-12 As shown, the pump device is used in a dishwasher. The pump device includes a disinfection / sterilization lamp 2022, which faces the receiving cavity 200. The light-transmitting part 201 of the pump body 2 is made of a light-transmitting material. The disinfection / sterilization lamp 2022 is located outside the receiving cavity 200, and the light from the disinfection / sterilization lamp 2022 can penetrate the light-transmitting part 201.

[0054] In one embodiment, the light-transmitting portion 201 is at least a part of the side wall portion 202 of the pump body 2. The pump body 20 includes a mounting base 2021, and the disinfection / sterilization lamp 2022 is fixed to the mounting base 2021. The mounting base 2021 and the light-transmitting portion 201 are integrally formed.

[0055] like Figure 5 , Figure 6 As shown, in a further embodiment, the light-transmitting part 201 is the side wall part 202 of the pump body 2, and the pump body 2 is integrally formed. Furthermore, the material of the light-transmitting part 201 is glass, plastic, or quartz. The light-transmitting part 101 can be penetrated by light with wavelengths in the range of 400nm-10nm. The mounting base 2021 is integrally formed with the light-transmitting part 201, making manufacturing very convenient and facilitating mass production. Especially when the light-transmitting part 201 is made of glass or quartz, the integral forming of the pump body 2 can effectively reduce the installation connection between the light-transmitting part 201 and the mounting base 2021, thereby effectively solving the problem of fragile glass or quartz installation.

[0056] In another embodiment, such as Figure 15 As shown, the light-transmitting part 201 is part of the side wall part 202 of the pump body 2. The pump body 20 includes a mounting base 2021, and the disinfection / sterilization lamp 2022 is fixed to the mounting base 2021. The mounting base 2021 is integrally formed with another part of the side wall part 202. At least a portion of the light-transmitting part 201 is located within the area enclosed by the mounting base 2021. The disinfection / sterilization lamp 2022 faces the portion of the light-transmitting part 201 located within the area enclosed by the mounting base 2021.

[0057] In one embodiment, the disinfection / sterilization lamp 2022 can be an ultraviolet disinfection lamp. The disinfection / sterilization lamp 2022 is installed on the pump body 2 and irradiates the receiving cavity 200 of the pump device through the light-transmitting part 201. It can treat the receiving cavity 200 to kill bacteria, viruses and other microorganisms. Especially when the pump is used in household products such as dishwashers, since food residues are prone to breed bacteria and other microorganisms, the safety of pump use is improved by setting disinfection irradiation and other methods.

[0058] In one embodiment, the disinfection / sterilization lamp 2022 works in conjunction with the blade 4. The blade 4 crushes the residue, reducing the residue retention or even clogging the gaps in the pump, thus reducing the growth of bacteria and other microorganisms. The disinfection irradiation further disinfects and sterilizes the fluid flowing through the containment cavity 200, further reducing the growth of bacteria and other microorganisms.

[0059] In one embodiment, in the direction of the central axis of the pump body 2, the blade 4 is closer to the inlet 3 of the pump device than the disinfection / sterilization lamp 2022. In this way, the residue is first crushed by the blade 4 and then disinfected by the disinfection / sterilization lamp 2022. The blade 4 works in conjunction with disinfection irradiation, and the residue crushed by the blade 4 is more easily irradiated by the disinfection / sterilization lamp 2022, reducing the difficulty of irradiating the interior of larger pieces of residue or reducing the influence of irradiation shadows.

[0060] Furthermore, the disinfection / sterilization lamp 2022 is installed in the light-transmitting part 201 of the pump body 2 and located outside the receiving cavity 200. Compared with the technology of extending the disinfection / sterilization lamp 2022 into the receiving cavity 200, it can effectively solve the sealing problem, improve the actual performance of the pump device, reduce the probability of leakage under high pressure, and also reduce sealing costs on another level.

[0061] In another embodiment, the pump device includes a housing, a pump body 2 and at least a portion of a drive unit 1 located within the space enclosed by the housing, and a disinfection / sterilization lamp 2022 fixed to the housing; specifically, in a dishwasher, at least a portion of the pump body 2 and the drive unit 1 is installed in a mounting cavity of the dishwasher, the housing is the cavity wall corresponding to the mounting cavity, and the disinfection / sterilization lamp 2022 is fixed to the cavity wall and faces the receiving cavity 200.

[0062] In one embodiment, the mounting base 2021 has a mounting groove 20210, and at least a portion of the disinfection / sterilization lamp 2022 is located in the mounting groove 20210.

[0063] The disinfection / sterilization lamp 2022 is mounted to the light-transmitting part 201 via the mounting base 2021. Since the disinfection / sterilization lamp 2022 is mounted on the outside of the pump body 2, the mounting base 2021 is also conveniently located outside the light-transmitting part 201. In other embodiments, the mounting base 2021 can also be fixed to the light-transmitting part 201 by welding or other techniques. Furthermore, the disinfection / sterilization lamp 2022 can emit ultraviolet light with a wavelength in the range of 400nm-10nm. This ultraviolet light passes through the light-transmitting part 201 and irradiates the receiving cavity 200, thereby achieving a disinfection / sterilization effect on the receiving cavity 200.

[0064] In one embodiment, such as Figure 11 As shown, the pump assembly includes a mounting cover 2024, a mounting base 2021, and a mounting cover 2024. One of the mounting base 2024 and the mounting cover 2024 has a snap fastener 20211, and the other has a slot 20241 that matches the snap fastener 20211. The mounting cover 2024 and the mounting base 2021 are fixedly mounted.

[0065] The disinfection / sterilization lamp 2022 is installed in the mounting slot 20210, and the mounting cover 2024 and the mounting base 2021 are engaged to prevent the disinfection lamp from falling out of the mounting slot 20210. In a further embodiment, the mounting cover 2024 has a through opening 24242, which is smaller than the outer diameter of the disinfection / sterilization lamp 2022 for wire routing; in yet another embodiment, the opening 24242 of the mounting cover 2024 may not be smaller than the outer diameter of the disinfection / sterilization lamp 2022, in which case sealant 2023 can be poured through the opening 24242 after the wire is led out.

[0066] In one embodiment, the pump device includes a sealant 2023, a portion of which is located in the mounting groove 20210 and another portion of which is located in the opening 24242. The sealant 2023 has a wire hole 20231. The pump device has a connecting wire 14, which is connected to a disinfection / sterilization lamp 2022. A portion of the connecting wire 14 is located in the wire hole 20231.

[0067] Understandably, the sealant 2023 is located outside the light-transmitting part 201 and is not subjected to high fluid pressure, making it relatively easy to meet the installation requirements. The sealant 2023 is mainly used to stabilize and prevent external dust, water droplets, and other contaminants from polluting the disinfection / germinating lamp 2022, thereby reducing the probability that the disinfection / germinating lamp 2022 will be affected by adverse external factors and its performance will be reduced.

[0068] The sealant 2023 also acts as a buffer. During the actual use of the pump device, there is a certain amount of vibration. Since the disinfection / germination lamp 2022 is installed in the light-transmitting part 201, it also vibrates. The sealant 2023 fills the mounting groove 20210 and covers the disinfection / germination lamp 2022, which can reduce the vibration of the disinfection / germination lamp 2022 to a certain extent and increase the installation stability of the disinfection / germination lamp 2022.

[0069] In another embodiment, such as Figure 12 As shown, the pump device includes an abutment portion 2025 that is fixed or integral with the mounting cover 2024. The pump device has a wire hole 20231 that passes through the abutment portion 2025 and the mounting cover 2024. At least a portion of the abutment portion 2025 is located in the mounting groove 20210 and abuts against the disinfection / sterilization lamp 2022. The abutment portion 2025 can be integrally formed with the mounting cover 2024, or the abutment portion 2025 can be made of a relatively flexible material such as rubber or plastic and fixed to the mounting base 2021 by means of adhesive bonding or other methods.

[0070] In one embodiment, there are at least two disinfection / sterilization lamps 2022, with each mounting base 2021 corresponding to one of the disinfection / sterilization lamps 2022. The at least two disinfection / sterilization lamps 2022 are evenly distributed in the light-transmitting part 201, and the at least two disinfection / sterilization lamps 2022 are connected in series or in parallel.

[0071] At least two disinfection / sterilization lamps 2022 are evenly distributed in the light-transmitting part 201 to reduce the lamp dead zone and make the receiving cavity 200 as illuminated as possible.

[0072] In one embodiment, the outer surface of the bottom wall corresponding to the mounting base 2021 is flat, and the disinfection / germinating lamp 2022 fits against the bottom wall corresponding to the mounting base 2021. The mounting base 2021 can be integrally formed with the light-transmitting part 201. During the forming process, the outer surface of the bottom wall corresponding to the mounting base 2021 can be made flat by using a mold. In this way, the disinfection / germinating lamp 2022 can illuminate the receiving cavity 200 as perpendicularly as possible, reducing the amount of light that fails to illuminate the receiving cavity 200 due to refraction and other factors, thereby increasing the working efficiency of the disinfection / germinating lamp 2022.

[0073] In one embodiment, the pump device includes a heating plate 21, which is mounted on the pump body 2. The heating plate has an inlet, and a portion of the inlet 3 is installed at the inlet. In this case, the pump with heating function provides power to the conveyed fluid and heats the fluid flowing through its pump chamber, allowing appliances such as dishwashers to operate more efficiently at a certain temperature. Further, in one embodiment, the heating plate is located at the end of the pump body 2, and the fluid flows through the heating plate and into the pump's receiving cavity 200, and then flows out.

[0074] In one embodiment, such as Figure 13 , Figure 14 As shown, the pump device includes a protective cover 12, which is installed with the heating plate 13. The protective cover 12 covers at least a portion of the heating plate 13. The protective cover 12 has a first opening 122 at its center for the inlet portion to extend out, and a second opening 123 at its side for the electrical contact portion 132 of the heating plate 13 to extend out. The protective cover 12 provides a certain degree of protection for the heating plate 13, reducing the impact of external dust and other impurities on the heating plate 13 and preventing collisions.

[0075] Furthermore, the heating plate 13 has a first bend buckle 131 installed on the edge portion 21 of the pump body 2, and the protective cover 12 has a second bend buckle 121 installed on the first bend buckle 131. The first bend buckle 131 fastens at least a portion of the edge portion 21 of the pump body 2, and the second bend buckle 121 fastens at least a portion of the first bend buckle 131. The edge portion 21 of the pump body 2, the first bend buckle 131, and the second bend buckle 121 are sequentially snapped together, which is very convenient and they are basically located at the same stress position. The second bend buckle 121 fastening the first bend buckle 131 can further make the first bend buckle 131 firmly fasten the edge portion 21 of the pump body 2, resulting in a stable structure.

[0076] The above are merely typical specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technical solutions, concepts, and designs obtained by those skilled in the art within the technical scope disclosed in the present invention by making equivalent substitutions or changes to the technical solutions and inventive concepts of the present invention should be covered within the scope of protection of the present invention.
